The Soil & Water Assessment Tool is a small watershed to river basin-scale model used to simulate the quality and quantity of surface and ground water and predict the environmental impact of land use, land management practices, and climate change. SWAT is widely used in assessing soil erosion prevention and control, non-point source pollution control and regional management in watersheds.
Introducing SWAT+, a completely revised version of the SWAT model. SWAT+ provides a more flexible spatial representation of interactions and processes within a watershed.

Short Survey Request
Researchers at The University of Iowa are investigating natural infrastructure practices to reduce flood and waterborne nitrogen risks and are seeking expert opinions regarding their effectiveness. Please consider completing the following short survey, which should take no more than five to ten minutes. The survey consists of three main sections where you will be asked to qualitatively evaluate the relative effectiveness of eight common natural infrastructure practices. Your input is greatly appreciated!
Call for Papers: Journal of Hydrology Special Issue
