SWAT+
Introducing SWAT+, a completely revised version of the SWAT model. SWAT+ provides a more flexible spatial representation of interactions and processes within a watershed.
SWAT 2012
The SWAT model is a command line tool that uses text input and output files. See the other links on this page for interfaces and tools for SWAT 2012.
SWAT 2012 Interfaces
- ArcSWAT
ArcGIS-ArcView extension for developing SWAT models - QSWAT
QGIS extension for developing SWAT models - SWAT Editor
Interface for editing SWAT inputs - SWAT-CUP
Sensitivity, calibration, validation, and uncertainty analysis
Output Analysis
- SWAT Check
Helps to identify potential model input parameters issues - SWAT Output Viewer
Alternative tool to quickly view and analyze SWAT outputs
SWAT Community Tools
- SWAT-C
SWAT-Carbon is a watershed scale model that converges terrestrial and aquatic carbon cycles at the watershed scale. It is based on the SWAT2012 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. - R-SWAT
Free, open source, graphical user interface for SWAT/SWAT+ calibration, parameter sensitivity/uncertainty analysis. For help see the user group and tutorial videos. - SWAT+ Toolbox
SWAT+ Toolbox is a user-friendly tool for SWAT+ model adaptations. Get the most recent version from the Additional Tools section of the SWAT+ page. - SWATplusR
