Starting a new project? Use SWAT+
SWAT2012 remains supported with bug fixes; all executables and tools (ArcSWAT, QSWAT, SWAT-CUP) are maintained for existing projects. New projects should start with SWAT+: a modernized, highly flexible ecohydrological model built with a streamlined setup and advanced code structure. Go to SWAT+.

SWAT2012 Community Tools
TASC is a watershed scale model that converges terrestrial and aquatic carbon cycles at the watershed scale. It is based on the SWAT-Carbon model and has unique functions to assess impacts that agricultural management and climate change have on a wide range of processes and indicators, such as soil organic carbon storage, nitrous oxides emissions, freeze-thaw cycles/water temperature, and riverine carbon fluxes.
Free, open source, graphical user interface for SWAT/SWAT+ calibration, parameter sensitivity/uncertainty analysis. For help see the user group and tutorial videos.
