This interim report summarizes results obtained for the project through May 1981. The objective of the study is to develop rainfall loss parameters for localities in Virginia. For this purpose, the state has been divided into eleven hydrologic regions, and loss parameters will be determined for three or more selected in each of these watersheds. Parameter selection curves will then be derived for the regions. To date 66 storm events across five hydrologic regions have been analyzed to obtain loss parameters. Of the five regions, Region P2, the piedmont portion of the James River Basin, has been completed. The results for this region are presented in this report.
A procedure is presented by which regional unit hydrograph and loss rate parameters are estimated for the generation of design storm hydrographs for w...
The effects of urbanization on the Corps of Engineers' HEC-I rainfall-runoff model parameters were examined. Data on rainfall events and corresponding...
