Water Quality Modeling Software for the United States | SWATGenX

SWAT+ nutrients and sediment with gSSURGO, NLCD, PRISM, and NSRDB already integrated — reports and model packages without manual GIS assembly.

What it is: SWATGenX provides water quality modeling software built on SWAT+ for nitrogen, phosphorus, and sediment at watershed scale, with national soils, land cover, and climate already integrated.

What it does: Move from basin selection to SWAT+ water-quality capable projects and supporting reports without manual SSURGO/PRISM/NLCD assembly.

Who it is for: Environmental modelers and planners working on TMDL-style questions, nonpoint source screening, and scenario comparisons across U.S. basins.
