Abstract:

A procedure is presented by which regional unit hydrograph and loss rate parameters are estimated for the generation of design storm hydrographs for watershed in Virginia. The state is divided into seven hydrological regions, and unit hydrograph and loss rate parameters are computed for each region and then related to watershed characteristics such as drainage area, channel slope, etc. The Corps of Engineers's HEC-I computer program was used to obtain optimal estimates of the Clark unit hydrograph and the standardized exponential loss rate function parameters. A total of 28 test watersheds and more than 160 storm events with corresponding stream flow data were analyzed. Parameter selection curves were developed with the results of the HEC-I analyses.
