A continuous simulation runoff yield analysis model is described which can be used to estimate runoff from any type of land use within a watershed. Such a model can be used to derive statistical data, such as annual average runoff volumes and exceedance frequencies that help to characterize storm water for management purposes. The paper has also presented a case for using this type of model in developing data to characterize storm water for water quality planning. A continuous simulation yield model, such as presented herein, can be used along with mean concentration data on the more common pollutants, to establish long-term pollutant yields for various land-uses or for entire mixed-use basins.
