RAINFALL ANALYSIS FOR DRAINAGE DESIGN. VOLUME II. LONG-DURATION PRECIPITATION FREQUENCY DATA

This report is an analysis of depth-duration-frequency of precipitation 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 the annual total precipitation. Methods of interstation interpolation 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 depth-duration-frequency analysis of precipitation with durations of one day to 60 days from 900 nonrecording rain gages. 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.
