Sample input/output files for SWAT simulations

Soil and Water Assessment Tool (SWAT) is a widely-used semi-distributed watershed hydrology model, freely available and actively supported by a global community of modelers and developers. SWAT has been validated in the prediction of flashflood discharge and has been applied to the Galveston Bay region for estimation of fresh water and sediment inflows and the impact of precipitation and land use changes on nearby Mission-Aransas National Estuarine Research Reserve SWAT physical processes include: a rainfall/runoff curve number-based approach to surface hydrology, vertical and lateral groundwater transport and storage, reservoir dynamics, eroded soil and sediment processes, chemical fate and transport dynamics including partitioning, transformation, and transport in different media (soil, runoff, surface water, sediment), and land use management. Complete theoretical documentation may be found at: https://swat.tamu.edu/docs/. We ran SWAT under different weather and hypothetical chemical release scenarios. This dataset includes the base input files to SWAT from which the different simulations can be recreated by changing the weather (.pcp, .tmp), selected chemical (basins.bsn) and time period (file.cio) inputs accordingly as well as corresponding sample output files. SWAT provided estimates of chemical transport in stormwater, eroded soil, and rivers, accounting for drainage from the entire Galveston Bay watershed, as boundary conditions and inputs into the Delft3D coastal model used to estimate flooding.
