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.

SWAT+

Introducing SWAT+, a completely revised version of the SWAT model. SWAT+ provides a more flexible spatial representation of interactions and processes within a watershed.

Submit an Abstract: AGU Fall Meeting - Chicago, IL & Online - 12-16 Dec. 2022

H004 - Advancements in Watershed Modeling: Hydrologic/WQ Processes and Management Implementations on Regulatory Science
Deadline: August 3rd (Wed), 2022

Since 2016, this modeling session has been initiated to provide broad discussions among international scientists from different disciplines. Specifically, contributions from the SWAT community are fruitful with great success. We hope mutual efforts in this session can advocate advanced insights for future investigation on both modeling development and the associated management strategies along with interactions from the government authorities. See you in Chicago!
