Abstract: A system based on continuous streamflow simulation was developed for use in DeKalb County, Georgia, to obtain information on flood frequency and flood hydrographs needed for land-use planning and drainage system design. The Stanford Watershed Model was used to generate storm period runoff volumes at small time steps for three soil types and impervious area. Runoff volumes which include the effects of antecedent rainfall and evapotranspiration are stored on computer files and used as imputs to a routing model. Required inputs for the routing model include: (1)Soil types and impervious areas for selection of runoff files; and (2)measurements of the drainage basin for channel and storage routing.
