What is XP-SWMM?

XP-SWMM is a comprehensive urban stormwater and wastewater modeling software. It combines one-dimensional (1D) hydraulic and hydrologic modeling with two-dimensional (2D) overland flow simulation. It's commonly used for designing and analyzing urban drainage systems, flood risk assessment, and developing stormwater management strategies. The software is based on the EPA SWMM model, but has been enhanced with additional features and capabilities.
