• Abstract:
  The effects of urbanization on the Corps of Engineers' HEC-I rainfall-runoff model parameters were examined. Data on rainfall events and corresponding streamflow hydrographs were gathered for five watersheds in rural and highly urbanized areas in Virginia. These data were used in the HEC-I program to obtain optimal estimates for the loss rate, unit hydrograph, and runoff hydrograph parameters. Regression analyses were then performed to derive prediction equations for these parameters in terms of the percent imperviousness of a watershed, which was used as the index of urbanization.
