This study was conducted in cooperation with the U. S. Department of 
Transportation, Federal Highway Administration, and 33 other agencies. 



This report is an analysis of depth-duration-frequency of precipi- 
tation in California and contains the annual series extreme values 
from about 30 rain gage networks in California. A statistical 
analysis of each record is available, giving 12 return periods 
ranging from 2 to 10,000 years and durations of 5 minutes to 60 days, 
including annual total precipitation. Methods of interstation inter- 
polation are given. Hourly precipitation records of the National 
Weather Service were reevaluated to develop 5-, 10-, 15-, and 30- 
minute extreme data. 

This volume reports precipitation, depth-duration-frequency data and 
analysis from 600 recording rain gages with durations ranging from 
5 minutes to 24 hours. 

The data contained in this report are intended for use in runoff 
computation using procedures such as the rational method or the 
unit hydrograph method. 

A cooperative computer data bank has been developed to store data on 
rainfall extremes and to periodically analyze data, as well as to 
maintain a continuous file for future use by cooperators.

FOREWORD 



Most civil engineering works must be evaluated with 
regard to the flood hazards they must withstand. The depth, 
duration, and frequency of rainfall are among the design deter- 
minants needed to establish the correct size of culverts, spill- 
ways, and other hydraulic structures. 

This report, presented in three volumes, is an update 
of earlier data compilations on this subject prepared by the 
Department of Water Resources. It presents a comprehensive 
collection of data on precipitation frequency in California. Its 
chief value lies in the listing of extreme annual rainfall for 
storm durations ranging from five minutes to 24 hours. These 
data were derived from observations of about 600 recording rain 
gages situated throughout the State. A statistical analysis of 
the record of each gage is included, along with a procedure for 
interpolating design rainfall between rain gages. 

Data can be analyzed by many different procedures. 
The analysis presented here is only one of a large number of 
interpretations that could be made of extreme annual data. In 
the long run, the engineer who uses these data is responsible 
for fitting the information to his/her particular needs. The 
data are expected to be of considerable value to flood control 
officials, highway designers, and others involved in consideration 
of drainage problems.

INTRODUCTION 



Bulletin No. 195 comprises three separately bound 
volumes that complement one another but are also useful as 
independent documents. Volume I contains short-duration pre- 
cipitation data. Volume II contains long-duration precipitation 
data. Voliime III contains intensity-duration-frequency curves. 

Volume I . The data are arranged by county and by drain- 
age areas within each county. The drainage areas are the major 
drainage provinces and hydrologic units shown on Plate 1. Two 
indexes list recording rain gage stations and the pages on which 
they appear. Index 1 is an alphabetic list of all gages appear- 
ing in Volume I. Index 2 lists these stations by drainage 
province and hydrographic unit. Specific storm durations 
reported in Volume I are 5, 10, 15, and 30 minutes; 1, 2, 3, 6, 
12, and 24 hours; and total annual precipitation. Specific 
return periods in Volume I are 2, 5, 10, 20, 25, 40, 50, 100, 
200, 1,000, and 10,000 years, and probable maximum precipitation. 

Plate 2 shows the location of each recording rain gage. 
Plate 3 depicts mean annual precipitation (MAP) . Plate 4 shows 
the mean annual one-hour storm. Plate 5 shows the regional 
coefficient of variation. Plate 6 shows the generalized slope 
of intensity-duration-frequency (IDF) curves. Plates 7 through 
12 show the percentage of MAP for one-hour storms with return 
periods of 10, 25, 50, 100 and 1,000 years, and the probable 
maximum precipitation (PMP) . 

Volume II . This volume contains tabulations of daily 
rainfall depth-duration-frequency for periods of 1, 2, 3, 4, 5, 
6, 8, 10, 15, 20, 30, and 60 days, and of total annual precipi- 
tation for all California stations for which 20 or more years 
of daily rainfall records were analyzed. The tables are arranged 
by drainage area. These records are those from which regional 
skewness and regional coefficients of variation were derived. 
(These factors are discussed later in this volume.) 

Volume III . This volume contains intensity-duration- 
frequency curves for stations with data for precipitation periods 
of 5 minutes to 24 hours. These stations are listed alphabeti- 
cally by county and by drainage area within each county. This 
volume is intended for use with the rational formula (Q = CiA) 
to compute runoff from small watersheds. 

Rainfall Extremes in California 

California's climate varies from the relatively humid 
North Coastal Hydrographic Area to the arid Salton Sea Basin, 
which includes the driest region on the North American continent.

OM3M M NOIlVildlOBMd 



Rainfall along the north coast of the State averages over 3,302 
millimetres (130 inches) a year at many locations, while mean annual 
rainfall at Glamas, east of the Salton Sea, is less than 25 milli- 
metres (one inch) a year. Rainfall extremes at other locations in 
California are also notable. The highest seasonal rainfall of record 
occurred in 1973-74, when 4,493 millimetres (176.88 inches) fell at 
Blue Creek Mountain in the North Coastal Area. In contrast, no rain 
fell for 767 consecutive days at Bagdad in the south eastern desert 
area from October 1912 to November 1914.^ 



The State's heaviest observed rainfall for one minute 
occurred in 1926 when 26 millimetres (1.03 inches) fell at Opids 
Camp in the San Gabriel Mountains. The heaviest one-day rainfall 
occurred in the same area in 1943, when 663 millimetres (26.12 
inches) fell at Hoegees. The greatest 30-day rainfall occurred 
at Honeydew in the North Coastal Area in 1955, when 2,106 milli- 
metres (82.90 inches) fell. The depth-duration relationship of 
California's greatest rains is shown on Figure 1. 

Most of California's rain is carried into the State by 
frontal storms that occur sporadically through the fall, winter, 
and spring. However, the desert zone in southeastern California 
receives its most intense rainfall from summer thunderstorms. 

More than 50 percent of these 
storms occur in July, August, 
— I or September (Figure 2) . Sum- 

mer storms carry large amounts 
of moisture derived from the 
extremely warm air mass from 
the Gulf of California, which 
in the summer is capable of hold- 
ing large quantities of water. ^ 

Uses of the Data 

Short-duration rainfall is a 
basic factor in determining the 
most appropriate size of drainage 
facilities. Many earlier reports 
on design rainfall have not devel- 
oped sufficient data on the spe- 
cific durations needed or suimna- 
rized all the available records.^''

having five or more years of record.* The information is intended 
for design engineers who need to determine the correct size of 
drainage structures. As an example, dam designers can use it to 
determine the hydraulic safety of dam spillways. The fact that 70 
percent of the 1,200 dams in California under the jurisdiction of 
the Department of Water Resources are situated in areas character- 
ized by watersheds with concentration times of one hour or less 
stresses the need for data on the frequency of short-duration 
precipitation . 

The mean annual precipitation is used as an indicator 
of short-duration precipitation. There is a considerable varia- 
tion in the relationship between short-duration rainfall and the 
yearly total rainfall for individual years. However, the over- 
all trend lines are similar for the extreme annual 5-minute, 60- 
minute, and 24 -hour rainfall and the total rainfall for the water 
year. The similarity in short-duration rainfall events and the 
concurrent year's total rainfall, shown on Figure 3 for Colby's 
in Los Angeles County, suggests that the use of mean annual pre- 
cipitation as a basis for estimating short-duration rainfall 
elsewhere in California is also reasonable. 

This assumption was tested in northern California as 
well. The correlation coefficient for the linear regression 
between calculated rainfall depths for various durations and 
return periods and mean annual precipitation is shown on the 
tabulation for stations in Contra Costa County on the following 
page. These positive correlation coefficients demonstrate that 
there is a strong correlation between design storms computed by 
the procedures used here and the mean annual precipitation for the 
range of durations and return periods used in this study. 

The usefulness of time-related data, such as this study 
presents, is limited by the length of the observation interval. 
The record from a rain gage read only once a year, for instance, 
cannot tell the observer how much rain fell in any one month or 
week, nor can a monthly observation provide rainfall data by the 
day, hour, or minute. Devices that record rainfall for the 
shorter periods of time are important for accurate rainfall data 
analysis. 

One of the drawbacks of a study of this type is that 
data storage capacity limits the total information which can be 
collected and analyzed economically. Restricting the data to an 



Recording rain gage networks that do not appear in this report were the 
Lake Tahoe gages of the University of Nevada's Desert Research Institute 
and about half the gages of the Pacific Gas and Electric Company's Lake 
Almanor weather modification project and numerous gages operated by the 
Joint Federal-State Flood Operations Center for flood forecasting, as well 
as numerous gages of the Los Angeles County Flood Control District.

annual series of extremes, as has been done in this study, has 
simplified the maintenance of the data file. Only the greatest 
depth of rain for each year for the specific durations under study 
contributes to the depth-duration-frequency tables in this report. 
(Precipitation data in this report include rainfall and snowfall 
but not dew or frost. Sometimes "rainfall" is used when the 
meaning includes "rain and snow".) 

Data Banks 

A permanent data bank containing the data appearing in 
this report has been established in the Stephen P. Teale Consoli- 
dated Data Center. Short-duration data, reported in this volume 
and in Volume III, are filed on a nine-channel magnetic tape as 
"RAIN". Maintenance is by an "Edit Update" program supported by 
the California Department of Transportation (Caltrans) and 
developed in the Office of Computer Systems of that agency. Roy 
Chalmers, Headquarters Hydraulics Engineer, Division of Project 
Development, is Caltrans' representative for individuals who need 
more specific information on the system. 

Another permanent data bank containing long-duration 
data (for 1 to 60 days), reported in Bulletin No. 195 as Volume II 
is filed in the Computer Systems Office of the Department of Water 
Resources on a seven-channel magnetic tape. The procedure for 
editing and manufacturing the daily rainfall frequency data file 
is Computer Process 842. Data are retrieved and analyzed by Com- 
puter Process 84 3, either by watershed or by county.

These data banks could easily hold the records for all 
6,000 rain gages in California with a minimum of cost for data 
storage and analysis. They will accommodate a variable format for 
storms of any specified duration. The standard durations used 
here are recommended for those data sets from which extreme annual 
storms of other durations have not already been extracted. 

The data banks are a truly cooperative enterprise between 
the Department of Water Resources and the agencies listed under 
"Acknowledgments" , which have contributed the data reported in 
Bulletin No. 195. The information filed in these banks is avail- 
able to all cooperators in this study. 

It is essential that the work done in this study be 
updated periodically to surmount the limitations of previous 
studies, as well as to offset the data deficiencies in this 
report caused by the brevity of some records. The most impor- 
tant of these earlier publications is Technical Paper No. 40^ 
published in 1961 by the U. S. Weather Bureau. This report sum- 
marized data for storm durations of 1 hour to 24 hours and return 
periods up to 100 years. The work has been widely used in Cali- 
fornia, even though its usefulness has been lessened because it 
depicts rain frequency for the State on a map drawn to a scale 
of 1:10,000,000. The basic data in the report are worthwhile, 
however, and they have accordingly been incorporated into the 
present study. In 1973, the National Weather Service developed 
a new rain frequency atlas for California'* that overcame the 
previous lack of graphic detail with maps drawn to a scale of 
1:1,000,000. This atlas provided data for 6-hour and 24-hour 
storm durations and return periods up to 100 years. Other related 
reports are listed as "Additional References".

RECORDING RAIN GAGES 



Data from three types of recording rain gages have 
been used in this report: weighing gages, Fischer-Porter punched 
tape gages, and tipping bucket gages. 

Weighing Gages 

Weighing gages, which were installed in great numbers 
in California in the early 1940s, record inches of rainfall on a 
chart fixed to a rotating drum. Most of the charts record as much 
as 304.8 millimetres (12 inches) of rain. The recording pen logs 
up to 152.4 millimetres (6 inches) and then reverses to log 
another 152.4 millimetres. On some, the vertical scale is 
increased so that 63.5 millimetres (2.5 inches) on the chart 
represents one inch of rain. 

Speeds at which the drums revolve vary considerably. 
Most of them record a 24-hour period in one complete revolution, 
with one hour shown as 12.2 millimetres (0.48 inches) and one 
day as 294.6 millimetres (11.6 inches) (horizontal). Some charts 
record four- or seven-day periods in one revolution. The briefer 
the period of time that a gage chart records in one revolution, 
the more accurately the record of short-duration extremes of 
precipitation can be obtained. The time resolution of a daily 
chart exceeds that of a four-day chart, for example. For 
intervals up to ten minutes, ^ maximum rainfall intensities 
obtained from weighing gages with a six-hour rotation of the drum 
(49.77 millimetres per hour) (1.92 inches per hour) were found 
to be significantly greater than those obtained from gages with 
a 24-hour rotation. 

For this study, data for durations as short as five- 
minutes were extracted from daily charts; 15-minute values, from 
four-day charts; and 30-minute values, from weekly charts. 

Fischer-Porter Gages 

Fischer -Porter punched tape recording rain gages first 
came into wide use in the late 1960s. These gages generally 
record rainfall in tenths of inches, with 15-minute rainfall 
totals. They function quite well where telemetry is important. 
But the one-tenth depth and 15-minute intervals are not adequate 
for the needs of drainage climatology on small watersheds. In 
this report, the extreme values obtained from these gages are 
reported to hundredths of an inch to bring their records into 
conformity with the computer analysis of the weighing gage records. 
Records from Fischer-Porter gages are indicated by the zero that 
always appears in the hundredths column in the maximum annual pre- 
cipitation tables in this volume.

Tipping Bucket Gages 

Tipping bucket rain gages are coming into wide use 
because these instruments can be equipped with long-term event 
recorders that operate unattended for months and lend themselves 
readily to telemetry. California's oldest recording rain gage 
records are from tipping bucket gages. The main Weather Service 
offices in California were equipped with tipping bucket gages in 
the early 1900s, but this type gage has been coming into wide 
use only in recent years. 

Limitations of Recording Rain Gages 

Those applying the data contained in this report are 
cautioned about the inherent and unavoidable shortcomings of 
records taken from recording rain gages. Rodda^ states: "Rain 
gages, as usually installed, regularly underregister the quantity 
of rain..." "...all rainfall... measurements are necessarily 
relative and they are at best precise rather than accurate." 
Studies by the Illinois State Water Survey^ indicated that the 
Weather Bureau's recording gages catch 2.5 to 6 percent less 
rain than their nonrecording gages. 

Precipitation gages generally undermeasure because of 
instrumentation limitations and aerodynamic problems. (Jones^ and 
Renard and Osborn^); therefore, the extreme rainfall data from 
recording rain gage charts is generally underestimated. Under- 
estimation of rainfall is caused by poor time resolution and 
errors in selecting the largest storm, as well as the poor aero- 
dynamic characteristics of rain gages. 

Gages placed at sites that receive heavy snowfall are 
occasionally covered with a cap of snow that prevents them from 
functioning. Snow also greatly reduces estimates of precipita- 
tion intensity by adhering to the sides of weighing gages, thus 
delaying the operation of the weighing mechanism until the snow 
melts. The loss of record caused by snow is overcome when heating 
devices are attached to gages located in snowy regions. 

Wind is another problem because it also causes gages to 
underregister. The aerodynamics of wind on falling rain and the 
interception of wind-driven rain by rain gages have been under 
study for many years. Koschmieder° reports that wind blowing at 
the rate of 24 railes per hour on an unprotected gage reduces by 
half the catch of a ground level gage. 

Snow and wind are frequently responsible for interrup- 
tions in rainfall records. About 10 percent of the recording 
rain gages reported by the National Weather Service^ show loss of 
record in midwinter, whereas only two percent show a midsummer 
loss. Furthermore, the gage observer may often be unaware of 
the loss of record from interference by wind or snow.

It has not been possible in this study to adjust the 
data for overcapping by snow and wind. Therefore, the user of 
these data should probably select a longer return period as a 
safety factor. In this study, rain gage catch has been assumed 
to be actual rainfall .

ANALYSIS OF THE DATA 



Basic Statistics 

A few of the equations of statistics are basic to 
this study, and_it is useful to state them here. The equa- 
tions of mean (M) , standard deviation (S) , coefficient of 
skew (g) , coefficient of kurtosis (k) , and coefficient of 
variation (CV) are shown here.

Where X = the magnitude of an event

N = the number of events 

The mean expresses the central tendency of the data set. 
The standard deviation measures the deviation from the mean. The 
skew shows the lack of symmetry, or lopsidedness, that occurs in 
a rainfall data set due to bounding by a lower limit at one end 
and by virtually no upper rainfall limit at the other. Kurtosis 
is used here to test for appropriateness of various frequency 
distributions. The coefficient of variation measures the varia- 
tion of the data set. 

A number of probability distributions have been found 
to be adequate for hydrologic frequency analysis; these include 
the normal, exponential, Gumbel, log-normal, log Pearson's Type III, 
Pearson's Type III (Gamma), and Weibull distributions.^" For each 
distribution, there exists a unique relationship between the coeffi- 
cients of skewness and kurtosis. The Pearson's Type III distribu- 
tion was found to be the best model for precipitation frequencies 
for storm durations of 5 minutes to 30 days based on the skew- 
kurtosis criteria shown on Figure 7, and the Weibull distribution 
was found to be better for 6 0-day durations and annual total 
precipitation, as well as for extreme annual runoff data.

The precipitation depth-duration-frequency tables in 
Volumes I and II were prepared with the use of the Department's 
Computer Program No. 3024. This program uses the general equation 
for hydroloqic frequency analysis from Chow's Handbook of Applied 
Hydrology : ^ ^ 

P. . = P.+K.S. 
Di 131 

where j refers to return period in years 

i refers to specific storm duration in minutes, 
hours, or days 

P.. = precipitation in inches for return period 
^ j and duration i 

P. = mean maximum annual storm for duration i 

1 

K. = frequency factor (in standard deviations) for 
•^ return period of j years (see Table 1) 

S . = standard deviation of maximum annual storm 
^ for duration i 

The frequency factor (K) used here is from the Pearson's 
Type III distribution^* and is related to the return period, as 
shown on Table 1. As an example of the significance of skewness 
in hydrologic frequency analysis, a 1,000-year storm is defined 
as the mean plus 3.67 standard deviations for a skewness of 0.4 
and the mean plus 5.91 standard deviations for a skewness of 2.0. 

Regional coefficients of skewness (Sk) are used because 
skewness is quite sensitive to large storm events in small statis- 
tical samples, such as these rainfall records. To illustrate the 
sensitivity of skewness, the largest daily rainfall from 79 daily 
rainfall records, each having 70 or more years of record, was 
normalized in terms of standard deviations in excess of the mean. 
The coefficient of determination between the normalized maximum 
daily rainfall and the coefficient of skewness was 0.74, indica- 
ting that 74 percent of the variation in the coefficient of skew- 
ness is related to the size of the largest daily event in the 
rainfall record. 

Regional Coefficients 

Regions in California having similar coefficients of 
skewness and variation were selected. Averages of the coefficients 
of individual stations were developed within each region. These 
station values are weighted by the length of record at each 
station. 



-15- 



The coefficients of skewness and variation were found 
to be similar for storm durations ranging from 5 minutes to 60 
days, as shown on Figure 4. In this report, the working values 
of these coefficients for durations of 5 minutes to 12 hours 
have been adopted. These are the same as the one-calendar-day 
values from the daily records summarized in Volume I. Daily, 
rather than hourly, records are used for developing these regional 
values because so much more data are available for the daily 
recording stations. Two values of coefficients are used here: 
one for durations of a day or less, and one for the annual total 
rainfall (Figures 5 and 6) . Within each region, the annual totals 
of skew and variation are plotted for each region below the values 
for one day and less. It is anticipated that future refinements 
of this study will include the development of more objective 
procedures for establishing regional coefficients of skewness and 
variation. 

Frequency Distributions 

The criterion for the selection of a frequency distri- 
bution to represent extreme annual precipitation for this report 
is illustrated by the skew-kurtosis relationship shown on 
Figure 7.^° This figure shows curves representing log-normal, 
Weibull, and Pearson's Type III distributions, as well as points 
representing normal and Gumbel distributions. The data points 
represent weighted averages of skew and kurtosis from 512 sta- 
tions with 21,934 station-years of record at daily rainfall 
measuring stations. The Pearson's Type III distribution is the 
clear choice for all storms lasting up to 30 days. The Weibull 
distribution is the best choice for 60-day storm durations and 
for yearly total rainfall. However, the Pearson Type III dis- 
tribution is used throughout this study. Previous work^ ° summa- 
rized on Figure 7 indicates that the Type III is the appropriate 
choice for short-duration precipitation extremes as well. 

Fixed-Interval Corrections 

Empirical values of the ratio of the true to fixed- 
interval average maximum precipitation were described in the 
U. S. Weather Bureau's Rainfall Frequency Atlas^ as: 

Clock-Hour vs. 60-Minute and Observational-Day 
vs. 144 0-Minute Rainfall — In order to exploit the 
clock-hour and observation-day data, it was necessary 
to determine their relationship to the 60-minute 
and 144 0-minute periods containing the maximum rain- 
fall. It was found that 1.13 times a rainfall value 
for a particular return period based on a series of 
annual maximum clock-hour rainfalls was equivalent 
to the amount for the same return period obtained 
from a series of 60-minute rainfalls. By coincidence, 
it was found that the same factor can be used to trans- 
form observational-day amounts to corresponding 1440- 
minute return-period amounts. ..."

Weiss^3 in 1964 published a theoretical derivation of 
the ratio of true to fixed-interval maximum precipitation (F) 
based on a probability model. As described, the ratio applies 
only to the averages of extreme events, rather than to individual 
yearly data. Values of (F) , as calculated by Weiss, are quoted 
here for various numbers of consecutive time intervals (n) : 



n

12 


24 


F 


1.143 


1.044 


1.022 


1.011 


1.005 



Weiss describes these ratios as independent of the time interval 
under study and as equally valid when used to describe hourly, 
daily, or monthly extreme data. 

The values of clock-hour correction (which have been 
used in this study) are shown in the following tabulation:

The interval can be in any uniform time increments. These clock- i 
hour corrections are also used as calendar-day corrections when a 
uniform once-a-day observation time is used. The same concept 
can be applied to any discrete fixed beginning and ending time 
interval, whether it is minute, hour, day, or month. These fixed 
interval corrections are too high for daily rainfall data in the 
desert areas, but no better ones are currently available. This 
is an area which still needs further investigation. 

Partial Euration Series and Annual Series 

Two methods exist for extracting the extreme values of 
time series data. In one of these, the partial duration series, 
the highest values of the total series are selected, regardless of 
the time at which they occur. In the second, the annual series, 
the highest value for each year is selected. When analyzed, the 
results from an annual series affect only relatively short return 
periods. The two series merge into one for return periods of 
more than ten years. Mathematically, the annual series is a 
complete series and the partial duration series is only the upper 
part of a total series. Hence, the partial direction series is 
difficult to use. 

The partial duration series is that portion of the 
extreme values which exceed a given base level, no matter when 
they occur. With this series, an analysis may include one year 



-20- 



in which several large rain events occurred and other years in 
which no storms as large as the base level occurred. The partial 
duration series is used for studying storms which have return 
periods of less than five years; longer return periods show little 
substantial difference. 

Partial duration series analysis requires the data 
analyst to use foresight in selecting a base level of storm events 
for a predetermined number of data points. 

The annual series consists of the largest annual value 
for each year, with only one value per year. Langbein^** has com- 
pared the results of the annual series to the partial duration 
series, as shown by the following conversion factors: 



Return Period in Years

Partial Duration 
Series 


1.16 


1.58 


2.54 


5.52 


10.5 


100.5 



It is easier perhaps to convert partial-duration series 
to annual series by using the following factors from Technical 
Paper No. 40 (Hershf ield) ^ . 



Return period 



Conversion factor

5-year

The annual series provides one great advantage over 
the partial duration series: ease of data file management. When 
the files of extreme data are updated, one year's record can be 
added to the data file for each year without regard to prior 
data files. 

Depth-Duration-Frequency Tables 

The observed maximum annual rainfall for each duration 
is tabulated for each year on the short-duration stations used 
in Volume I . The data were not listed for the long-duration 
stations of Volume II, but the data can be supplied to those 
users who choose to analyze the data for themselves. 

The depth-duration-frequency tables included in this 
report in Volvimes I and II have several parts. The first part. 



-21- 



including station number, name, elevation, location, and county 
code, is explained in "Key to Station Descriptions" in this report 

The second part of the tables is a matrix of columns of 
storm events ranging from 5 minutes up to 24 hours as well as the 
annual total, and return periods ranging from 2 to 10,000 years, 
with a probable maximum precipitation (PMP) estimated as the mean 
plus 15 standard deviations. ^^ The calendar, fiscal, or water 
year total precipitation is coded as C YR , F YR , or W__YR. 

The third part of the table contains the mean, which 
is the arithmetic average; the clock-hour correction, ^ ^ where 
appropriate; the calculated skew; the regional skew; and the 
actual skew, which is used on the computations for the duration- 
return period matrix. 

The fourth part of the table contains the slope of the 
log-intensity/log-time plot, and the one-hour intercept of the 
log-mean-intensity/log-time curve, as determined by a least square 
fit for those durations of 5 minutes to 3 hours. The coefficient 
of determination is for this least square fit. The one-hour inter- 
cept is also expressed as a fraction of the mean annual precipita- 
tion, as well as units of inches. The ratio of the average 
calculated coefficient of variation for durations of 5 minutes 
to 3 hours over the regional coefficient of variation is coded as 
Average Calc CV/Used CV . 

The fifth part of the table contains the kurtosis, which 
is the fourth moment function. The number of data points used 
in the computations for each column is coded as N. The year in 
which the highest rainfall of record occurred is coded as Record 
Year . The highest precipitation for each duration is indicated 
in the row labeled Record Maximum . Normalized Max is the record 
maximum in units of standard deviations in excess of the mean 
for each duration. The calculated coefficient of variation is 
coded as Calc. Coef. of Var . The regional coefficient of varia- 
tion is coded as Regn. Coef. Var . The coefficient of variation 
used in this report is coded as Used Coef. Var . 

The sixth part of the table contains dimensionless 
ratios of precipitation for return periods of 10 to 10,000 years, 
expressed as percentages of the mean annual precipitation, and 
coded as RP 10/A, etc. Mean/A refers to the mean event for each 
duration as a fraction of the mean annual precipitation. PMP is 
also expressed PMP/A (probable maximum precipitation expressed 
as a fraction of the mean annual rainfall (A) ) , so that the mean 
annual precipitation can easily be used as an interstation inter- 
polating device, as well as for comparing adjacent records for 
consistency. 

The data user is expected to be concerned mainly with 
the first two parts; the remainder of each table is printed in 
the interest of continued procedures development. 

-22- 



The last line of the depth-duration-frequency table 
states: "Where N is small (<25), results are not dependable." 
"Small" in this application means records of 25 years or less. 
From sampling theory^ ^ is derived the statement: errors are pro- 
portional to one over the square root of the sample size. 

Quality control on the precipitation depth-duration- 
frequency tables of this report is monitored by the coefficient 
of determination and ratio of the average calculated coefficient 
of variation to the used coefficient of variation. A coefficient 
of determination of 0.998 is considered a good fit of a straight 
line to the log-average-intensity/log-time curve. A value of 
0.98 or less suggests that a straight line is not the best model 
for this data set, or that the data are inadequate, especially in 
the shorter durations where chart resolution is poor or the 
effects of snow or wind are severest. The coefficient of deter- 
mination varies from zero for no correlation to 1.000 for a 
perfect correlation. 

The ratio of the average- calculated coefficient of 
variation to the use coefficient of variation varies from about 
0.5 to 2.0; for the ideal situation, it would be 1.00. This 
ratio is only for durations of 5 minutes to 3 hours. The 
coefficient of variation is subject to errors arising from inade- 
quate sampling of annual extreme values. Values of this ratio 
smaller than 1.00 represent instances in which the use of the 
calculated coefficient of variation would result in a smaller 
design storm. 

Safety Factors in Hydrology 

Engineers are accustomed to using safety factors in 
the design of structures. In designing storm protection works, 
such factors include "spillway design floods", project design 
floods", "1,000-year storms", "probable maximum precipitation", 
and other basis for rationalizing the use of very rare storm 
events. The fact that design storms are occasionally exceeded 
points out the need for an assessment of the risks of failure 
associated with selected return periods. 

Frequency analysis defines the event which can be 
expected once every "Y" years on the average. This does not 
imply that a "Y-year event" will occur regularly every "Y" years. 
Return periods, as well as flood magnitudes, are subject to 
analysis. For example, there is a two percent chance that a 50- 
year event will occur in any one year. 

The 10,000-year event with a skew of 1.3 is defined as 
the mean plus 6.64 standard deviations, as shown on Table 1. The 
10,000-year return periods based on 10 to 30 years of record will 
be considered of low statistical reliability. However, the use 
of a 10,000-year return period in hydro logic studies has consider- 
able utility and compensates for the low statistical reliability.

Since some dams have lives exceeding 100 years, and 
since a low level of risk, such as one-in-a-hundred chance of 
failure, is desirable, the joint probabilities of the two events 
can be calculated by multiplying, in this case, a one-in-a- 
hundred risk with a 100-year project life for a design return 
period of 10,000 years. 

The permissible level of risk during the project life 
can be considered when a return period is selected. A structure 
with a one-year useful life, such as a temporary cofferdam, for 
instance, for which a one percent chance of failure would consti- 
tute a permissible level of risk, would be designed for a return 
period of 100 years. 

The relationship of permissible level of risk and return 
period is shown on Figure 8 for a broad range of project lives and 
return periods. This graph, which was prepared from a probability 
formula in Hydrology for Engineers (Linsley, Kohler, and Paulhus, 
1958),^^ indicates a ten percent chance of a once-in-460-year 
event occurring in the next 50 years. Permissible risk is dis- 
cussed in depth in a paper by Ben Chie Yen.^^ 

Meteorological models of probable maximiim precipitation 
have been based on three physical limitations: 

Moisture in the air over a basin. 
Moisture transported into a basin by winds . 
The fraction of the inflowing moisture which 
will precipitate. 

These variables, which are difficult to measure directly, 
are commonly estimated for orographic and convective storm types. 
Models of the precipitation mechanism are generally calibrated by 
historical precipitation data. A good discussion of probable 
maximum precipitation (PMP) was prepared in 1967 by Vance Myers 
of the U. S. Weather Bureau. ^^ 

Statistical models represent a direct approach to 
estimating PMP with a minimum amount of assumption. A comparison 
of these two approaches to computing PMP was made by Hershf ield, ^ ^ 
who used the mean plus 15 standard deviations to estimate probable 
maximum precipitation. The value of 15 standard deviations was 
an upper enveloping value for extreme storms of record. The use 
of a given level of risk or a given number of standard deviations 
above the mean can be a management decision, when a relatively 
stable method of computing the means, the standard deviations, 
and the skew coefficients is available.

INTERSTATION INTERPOLATION 



An objective of this study is to develop a procedure 
for estimating extreme annual precipitation for various frequen- 
cies at any location in California. Two approaches are used 
here. The first is presented in a series of maps (Plates 7 through 
12) that show the extreme annual one-hour duration storm for 
return periods of 10, 25, 50, 100, and 1,000 years, and the 
probable maximum precipitation. The values appearing on these 
maps are expressed as percentages of the mean annual precipitation. 
The second approach is to map the statistical parameters (mean, 
coefficient of variation, coefficient of skewness, and slope of 
an intensity-frequency-duration curve) . Both approaches use a 
mean annual precipitation map^^ for interpolation between stations. 
The first approach is intended for direct use by engineers, and 
the second, for potential use in a computer-oriented application. 

The statistical parameters, when analyzed separately, 
will yield design storms which vary from the analysis for specific 
return periods (Plates 7 through 12) because of the effects of 
smoothing the maps of the mean and the coefficients of skew and 
variation. An analysis of the statistical parameters was developed 
for a computerized procedure in which the data user will interro- 
gate a data bank by a remote terminal. The user will enter the 
longitude and latitude of the center of the drainage area and 
receive an array of design storms for durations of 5 to 180 min- 
utes and return periods of 2 to 10,000 years. Economies have 
curtailed the implementation of this program, but the basic 
approach to its use is outlined here: 

Chow's general equation for hydrologic frequency from 
his Handbook of Applied Hydrology^^ is x = x (1 + CV K) , which 
for this study is: 

P. = MAP P (1 + K.CV) (a) 

3 : 

where P . = precipitation in inches per hour for return 
^ period j 

MAP = mean annual precipitation 

P = mean annual maximum 1-hour storm as a fraction 
MAP 

K. = frequency factor from Table 1 



CV = regional coefficient of variation 



-27- 



The intensity-duration relationship was assumed to be 
a linear log-log plot as follows: 

Log I = log P + n log H (b) 

where I = intensity in inches per hour for duration 
H in hours 

n = slope of curve 

n and P are computed by a least square procedure. 

Use of the concepts of equations (a) and (b) develops 
the following: 

I = (MAP) P (1 + K.CV) H-n (c) 

Kj is the only value in equation (a) representing 
different return periods. The entire storm is expressed as a 
fraction of the mean annual precipitation. 

The data of equation (c2_ is shown graphically in this 
report. MAP is shown on Plate 3; P is shown on Plate 4; Kj is 
tabulated on Table 1; CV is plotted on Plate 5; and n is plotted 
on Plate 6. In this procedure, the mean annual precipitation 
was used as an interstation interpolation device. Use of MAP 
would have required storing statewide maps of MAP, P, CV, n, and 
the regional coefficient of skewness as digital data in a computer, 

Coefficient of Variation 

The coefficient of variation (CV) is the standard devia- 
tion divided by the mean. It is used here to express the varia- 
tion from the mean of extreme annual rainfall. CV is plotted as 
a continuous surface on Plate 5 and is also shown as averages for 
specific areas on Figure 6. These regional averages were used to 
develop the depth-duration-frequency tables in Volumes I and II. 
The values in Figure 6 were visualized as a second generation 
estimate of CV, whereas the averages of Plate 5 are visualized 
third generation values for use in a future computer-generated 
analysis of CV. The use of the Plate 5 values should overcome 
the abrupt discontinuities which are evident in the adjacent zones 
of Figure 6. 

Slope of Intensity-Duration-Frequency Curves for California 

The one-hour storm is the basic unit of storm analysis 
used for the intensity-duration-frequency (IDF) curves shown in 
Volume III. Storms for durations ranging from 5 to 180 minutes 
are computed from the one-hour storm, using the slope of a curve 
of log intensity (in inches per hour) -log duration (in hours). 
This slope is derived from a least squares fit, using durations 
of 5, 10, 15, 30, 60, 120, and 180 minutes. Some of the stations 

-28- 



lacked data for all seven storm durations. In those cases, only 
the durations which were available were used to develop the mean 
and slope of the intensity-duration-frequency curves. 

The IDF curve for Eureka (Figure 9) is used to illus- 
trate the mean and slope of IDF curves for this report. The 
mean represents the one-hour intercept of the line fitted to the 
average annual extremes for each duration. In this report the 
slope is always negative when the units used are inches per hour. 
The slope is one of the regression constants from a log-log plot 
of the IDF curve.

RESEARCH IMPLEMENTATION 

The results of this study will replace the isohyetal map 
of California titled "Variation of 60-Minute Precipitation in 
California" that has been the standard referred to in the Highway 
Design Manual of the Department of Transportation. The isohyetal 
map of California has long been recognized as a very rough approxi- 
mation and generally was not used for design, if it was at all 
possible to obtain other more reliable data. The product of this 
study will permit designers to replace the isohyetal map with a 
data base that they can rely on. 

Computing and analyzing weather station data is a time- 
consuming manual task. Data are difficult to obtain, and fre- 
quently the desired data must be estimated by various means from 
skimpy and often obsolete records. A positive benefit that should 
be realized by the immediate dissemination of the data obtained in 
this report will be to provide data needed for hydrologic analysis 
without diverting manpower to make the statistical analysis. 

The analyses of this study are useful, and the rainfall 
data can be used directly from the report. The results should 
prove to be a valuable tool to anyone preparing rainfall-runoff 
estimates . 

This study will provide more accurate and reliable infor- 
mation on short-duration storms. The current practice of estima- 
ting short-duration rainfall of less than one hour as a constant 
percent of the clock-hour rainfall for any location in the State 
would be discontinued. The data that would be furnished by the 
proposed project will show the ratio of short-duration to one- 
hour storm for each station in the State. 

Additional benefits of this study would include safer 
and more economic drainage facilities, due to better estimates of 
rainfall maximums that also correspond more closely with the actual 
concentration time of water catchments. 

Another value of the study comes from gathering the 
great number of rain gage stations that have been collecting data 
and then compiling it into a usable and available whole. Hereto- 
fore, the data have existed, but only within the limits of the 
various local agencies — both public and private. This study brings 
all these data together into one publication. 

Another value is that a permanent data bank containing 
the data appearing in the report has been established in the Teale 
Data Center in Sacramento. Current plans include preparing an 
annual update of the data, which would be part of the Department 
of Water Resources' activity. 



-31- 



Another use for the data is in combination with the study 
report that is just being completed by the U. S. Geological Survey, 
Floods from Small Drainage Areas. The study examined the rainfall- 
runoff relation of many drainage basins throughout California. The 
data produced from this study will provide a more reliable method 
of relating known rainfall-runoff relationships with an estimated 
rainfall intensity-duration-frequency. The data can then be used | 
to estimate the 100-year frequency runoff from a previously gaged 
rainfall-runoff basin or used to estimate the runoff from a nearly 
similar ungaged runoff basin. This is a capability that highway 
designers have not been able to utilize heretofore.

KEY TO STATION DESCRIPTIONS 

Drainage Basin - Each of the 12 major drainage provinces is 

given a letter code, and the hydrographic units within each 
are designated by number codes. These are shown on Plate 1. 

Alpha Order Number - The alpha order numbers were originally 

assigned to each station to denote its alphabetic sequence . 
They are the same numbers used by the National Weather 
Service in the late 1950s. Alpha-numeric sequence niimbers 
are now assigned by referring to the latest alpha listing 
of the historic weather station name list. 

Subnumber - These numbers supplement the four-digit alpha order 
number and are used to maintain an alphabetical sequence of 
station names beyond the capability of the system used by 
the National Weather Service. 

Station Name - When no obvious station name exists, a name must 
sometimes be devised for a weather station. Frequently 
this is the name of the nearest post office, followed by 
the distance and direction in miles and 16 compass points. 
For example, Canby 11 SW denotes a station located 11 miles 
southwest of the post office at Canby. When two observers 
are situated at a single location, the town name is some- 
times followed by the name of the observer's location. An 
example of this: Stonyford Cooley Ranch, where Stonyford 
is the place name and Cooley Ranch is the observer's site. 
When two precipitation gages are situated at one site, one 
is also identified with a number, such as Folsom No. 2. 

The responsibility for selecting the station name rests with 
the agency or individual establishing the station. 

The space for station names is restricted by the computer 
to 25 columns; therefore, some abbreviations are necessary. 
Some common ones are : 

AP - Airport 

PH - Power House 
STA - Station 
HMS - Highway Maintenance Station 

FS - Fire Station 

RS - Ranger Station 

Elevation - The elevation of the ground surface at the gage is 
expressed to the nearest foot above mean sea level (USGS 
datum) . The elevation is generally obtained by interpola- 
tion between the contours of USGS topographic maps. 



-36- 






* Section, Township, and Range - The section, township, and range 
are based on the U. S. Public Land Survey, in which 6-mile- 
square townships are divided into 36 sections; these are 
further subdivided into 16 quarter-mile-square lots that 
contain roughly 40 acres. The township, range, and section 
used here are identical to those shown on the maps of the 
U. S. Geological Survey, with the official Department exten- 
sion of the sectioning into unsurveyed areas.

Tract 



40-Acre Tract - A letter code identifies the 
position of each tract within a section. 
The letters "I" and "0" have been omit- 
ted to avoid confusion with the numbers 
"1" and "0". 

Base and Meridian - The code for this column is: 

G - Gila and Salt River Base and Meridian 

H - Humboldt Base and Meridian 

M - Mount Diablo Base and Meridian 

S - San Bernardino Base and Meridian 

W - Willamette Base and Meridian 

Latitude and Longitude - Latitude and longitude are given to the 

nearest second, when the value is known. The National Weather 
Service lists its stations by degree and minute only. A zero 
value or a blank space for seconds in these columns generally 
means that latitude and longitude have been obtained from the 
Weather Service and have not been verified in the field by 
personnel of the Department of Water Resources.
