RAINFALL ANALYSIS FOR DRAINAGE DESIGN. VOLUME I. SHORT-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 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 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.
