Abstract

The AA. use the Regional Hydro-Ecologic Simulation System to examine interactions between internal watershed processes that lead to runoff production. Through a case study watershed in San Diego, the AA. address the issue of limited streamflow data for model calibration, a requirement that is often difficult to meet in smaller, ungauged watersheds. They illustrate how flow data from a similar watershed, combined with sensitivity analysis, can serve to compensate for this data limitation in the context of understanding urban impacts on hydrologic behavior. They then use this modeling approach to demonstrate that the conclusions made about the effects of urbanization on stream flow are a complex function of interactions between the watershed drainage network configuration and antecedent soil moisture conditions. Finally, they examine overall ease of use of the modeling approach used and discuss implications for environmental assessment
