SWMM-CAT allows users to evaluate climate change impacts on stormwater runoff volume and quality, and to explore how the application of various low-impact development (LID) options can be used to alter these hydrological parameters. SWMM provides a spatial and temporal analysis of runoff quality and quantity by dividing basins into multiple sub-catchment areas and analyzing runoff at different time steps. It covers a variety of different drivers that can cause runoff in urban areas, including rainfall, snowmelt, and groundwater percolation, among others, and also allows for mapping and modeling of different sub-catchment drainage system components, including pipes, channels, diversion structures, storage and treatment facilities, and natural channels.
