The United States Environmental Protection Agency (EPA) Storm Water Management Model (SWMM) is a dynamic rainfallrunoffsubsurface runoff simulation model used for single-event to long-term (continuous) simulation of the surface/subsurface hydrology quantity and quality from primarily urban/suburban areas. The evaporation seems quite low for my region (the. Recently a 2D overland mesh utility was introduced in PCSWMM. Application of this new component was evaluated using the same UK set of 2D hydraulic benchmarking tests used to evaluate the fourteen hydraulic packages. The tests ranged from simple flood analysis to major flood inundation simulations in complex terrain under various initial and boundary conditions, and shallow flows in urban areas with inputs from rainfall and sewer surcharge. Performance of SWMM5/PCSWMM2D in simulating these test conditions is presented, including model continuity error, stability issues and run time. InstallShield executable file for version 1.01 of the EFDC model and documentation. The effects of shape of the 2D cells, number of nodes/links on the model results are also presented.
