Abstract
"Synthetic temporal rainfall distributions derived by Huff (1967), Keifer and Chu (1957), Pilgrim and Cordery (1975) and Yen and Chow (1980) were evaluated for their applicability to hydrologic modeling for the southwestern Missouri area. First, the U.S. Army Corps of Engineers HEC-1 Flood Hydrograph Package was used to compute peak flows resulting from the ten largest rainfalls of one hour, two hour, three hour, four hour, and six hour durations recorded in Springfield and surrounding National Weather Service Stations from January 1956 to October 1988. Then the synthetic distributions were calculated to characterize rainfall for the total precipitation depths and HEC-1 was used to compute peak flows. Runoff computations were compared to those resulting from the observed natural rainfall events.
Results of this study indicate that on the average the Pilgrim and Cordery Distribution is slightly conservative (overestimates by an average of 14 percent) and would be most appropriate for use in the design of storm water improvements. Huff’s 2nd Quartile and Yen and Chow's distributions underestimate peak flows. Keifer and Chu's Chicago Method overestimates peak flows significantly"--Abstract, page iii.
