As an alternative to the conventional single‐peak design storms commonly used in hydrologic practice, a large number of Southeastern Pennsylvania storm events were selected from hourly U.S. National Oceanographic and Atmospheric Administration (NOAA) records, and their temporal distributions were analyzed. From these recorded events, design storms of a typical distribution were developed for storm durations between 6 and 18 hours. All of these generated design storms have two or more peaks. The conventional single peak as well as the “typical” multi‐peak storms were then applied to a simulated watershed. It was found that the multi‐peak storms consistently produced more dispersed hydrographs with lower runoff peaks than the conventional single peak storms.
