SWAT Model Description

​

The Soil and Water Assessment Tool (SWAT) model (Arnold et al., 1998) is the continuation of a long-term effort of nonpoint source pollution modeling by the USDA-Agricultural Research Service (ARS), including development of CREAMS (Knisel, 1980), SWRRB (Williams et al., 1985; Arnold et al., 1990), and ROTO (Arnold et al., 1995).

SWAT was developed to predict the impact of climate and management (e.g. vegetative changes, reservoir management, groundwater withdrawals, and water transfer) on water, sediment, and agricultural chemical yields in large un-gauged basins. To satisfy the objective, the model (a) is physically based; (b) uses readily available inputs; (c) is computationally efficient to operate on large basins in a reasonable time; and (d) is continuous time and capable of simulating long periods for computing the effects of management changes. SWAT allows a basin to be divided into hundreds or thousands of grid cells or sub-watersheds.

SWAT is GIS based model and for pre/post processing QGIS and ArcGIS is used.

SWAT 1 on 1 ONLINE Course:

 

When hydrology watershed modeling is in question learning by example is the best way. On that way participant is working with the area with which he is familiar with so in this course we will use data from your area. We will point you to databases in your region or World Data bases if local is not available. What we need to build a SWAT model is DEM (digital elevation model), Land Use/Land Cover, Soil map and climate data.

The 1 on 1 ONLINE course to learn SWAT should last about 10 hours and on the end the participant will be able to develop its own hydrology watershed model.
