Our review
Pros	Models saturated and unsaturated flow in 2D or fully 3D domains Handles variable density, reactive solute, and thermal-energy transport Flexible finite-element grids with lake and freeze-thaw capabilities	Delineates watersheds and sub-basins from terrain data. Connects GIS workflows with hydrologic and hydraulic modeling. GSSHA supports 2D groundwater–surface-water interaction and contaminant modeling.
Cons	Listed platform support is limited to Windows Reactive solute transport covers a single species Desktop deployment may not suit cloud-based team workflows	Groundwater modeling is centered on integrated GSSHA, not standalone simulation. Runs on Windows as desktop software. Paid editions start at $3,990 one-time.
Our verdict	SUTRA is a USGS groundwater simulator for saturated and unsaturated flow with constant or variable density. It supports single-species reactive solute transport and thermal-energy transport in two-dimensional and fully three-dimensional… Read the review →	Watershed Modeling System (WMS) is Windows desktop software for building and analyzing watershed models. It is aimed at teams working across terrain and GIS data, watershed delineation, hydrology, hydraulics, and floodplain mapping.… Read the review →
