Documentation
The Soil and Water Assessment Tool (SWAT) is a comprehensive model that requires a diversity of information in order to run. Novice users may feel overwhelmed by the variety and number of inputs when they first begin to use the model.
SWAT+
SWAT+ is the current version of the model. The documentation website provides information for the interfaces as well as model inputs.
