RAINFALL ANALYSIS FOR DRAINAGE DESIGN. VOLUME III. INTENSITY-DURATION-FREQUENCY CURVES

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 contains precipitation intensity-duration-frequency curves from 500 recording rain gages, based on maximum annual rainfall depths for 5 to 180 minutes. The information contained in this report is intended for use in runoff computation using procedures such as the rational method or the unit hydrograph method.
