2018 Brussels


The 2018 International SWAT Conference and Workshops will be held at Vrije Universiteit Brussel (VUB), Belgium, September 17-21. View the agenda and get more information.

Call for Abstracts

An integrated modeling workshop, sponsored by Cornell University and Iowa State University, will be held at the David R Atkinson Center, Cornell University, Ithaca, NY during April 3-5, 2019. The workshop organizers are Dave Keiser (Iowa State University), Cathy Kling (Cornell University) and Dan Phaneuf (University of Wisconsin, Madison). Abstracts are being solicited that describe integration of the Soil and Water Assessment Tool (SWAT), Agricultural Policy/Environmental eXtender (APEX) and/or other ecohydrological or environmental models, with economic models or other types of models. Accepted abstracts will also be considered for a special issue of Land Economics. Additional details regarding the topics of interest and abstract submission process.

Call for Papers

The following SWAT special issue journals are accepting submissions. You do not need to have presented at a SWAT conference in order to submit a paper. If you know others interested, please forward this information to them. The journals are:

The Soil and Water Assessment Tool (SWAT) is a public domain model jointly developed by USDA Agricultural Research Service (USDA-ARS) and Texas A&M AgriLife Research, part of The Texas A&M University System. SWAT is a small watershed to river basin-scale model 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. Read our fact sheet and disclaimer.
