Online Beginner Soil & Water Assessment Tool (SWAT) Workshop April 19-22

April 13, 2022

The Institute for Energy, Environment and Sustainable Communities is pleased to announce that Fulbright Scholar Dr. Raghavan Srinivasan from Texas A&M University will lead a Beginner SWAT Workshop next week. The workshop will be offered online  April 19-22, 2022. Interested participants should email and include their name and email address in order to be added to the final participants list.

For more details about the SWAT, see the following weblink:

The SWAT is a small watershed to river basin-scale model used to simulate the quality and quantity of surface and groundwater 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.

The SWAT model is the most widely used water quantity and quality assessment globally, with 5,000 peer-reviewed publications. More details about the model can be found here (

This workshop uses ArcSWAT (ArcGIS) based interface. Beginner courses are designed to introduce new users to the model, review necessary and optional inputs, and familiarize the user with the interface. It is assumed that attendees have a working knowledge of GIS and will not review basic concepts on GIS usage before covering the SWAT interface.

The following topics will be covered in this workshop:

  • Model overview (theory)
  • Model applications (theory)
  • Introduction to the SWAT interface (GIS)
  • Watershed delineation
  • Landuse and soil overlay
  • HRU delineation
  • Weather and remaining inputs to develop the SWAT model (including point sources) using the SWATEditor
  • Review of summary outputs
  • Using the SWAT Check program to identify possible problems
  • Finishing the SWAT simulation and saving results
  • Visualization and interpretation of SWAT outputs
  • Addressing user requests and clarifying anything covered during the first two days

About the presenter: Dr. Raghavan Srinivasan (Srini) is a professor in the Departments of Ecology and Conservation Biology and Biological and Agricultural Engineering, Director of the Spatial Sciences Laboratory at Texas A&M University, and Director of the Blackland Research and Extension Center. He received his doctorate from the Department of Agriculture and Biological Engineering, Purdue University, in 1992 and has spent over 30 years conducting watershed management and water quality modeling research and educating undergraduate and graduate students. He has 20 Ph.D. and over 25 M.S. graduates from his laboratory, and he also supervised tens of post-doctoral fellows over the years. He is instrumental in building capacity worldwide in more than 90 countries using the watershed and water quality model that he co-developed through training and technology transfer. More than 2000 scientists are trained and effectively using his model for their graduate curricula. Srini has organized more than 30 international SWAT modeling conferences worldwide. Srini has also served on US EPA Science Advisory Panels and workshops dealing with drinking water and water quality modeling. He has been awarded various national and international awards, including the University Distinguished Professor in 2022, Docteur Honoria Causa (Honorary Doctorate Award) by Paul Sabatier University – Toulouse III in 2013, College of Agriculture Distinguished Agriculture Alumni Award, Purdue University in 2015, Vice Chancellor's Award in Excellence for International Involvement in 2014, Texas A&M AgriLife Research Faculty Fellow in 2014 to name a few. He has over 250 peer-reviewed publications on research ranging from watershed management, water quality model development and applications, GIS and remote sensing, fate, and transport of pesticides and nutrients along with sediment and runoff. Current research in his laboratory focuses on developing 1) the salinity model in the watershed and river systems; 2) the development of bacterial fate and transport; 3) the development of emerging contaminants such as pharmaceuticals and 4) the impact of land-use change/management and climate change on agricultural production and hydrology as well as associated water quality impacts.
