Great Lakes SWAT Modeling Workshop

Western Lake Erie Basin PartnershipInternational Joint CommissionLimnoTechWorkshop Proceedings (PDF)The Water Center, together with the Western Lake Erie Basin Partnership, the International Joint Commission, and LimnoTech, hosted a Great Lakes SWAT Modeling Workshop at the University of Michigan on March 18-19, 2014.

SWAT, which stands for Soil Water Assessment Tool, is a powerful model that allows users to determine the impacts of land management practices on water, sediment, and nutrient yields in agricultural watersheds. Throughout the Great Lakes region, scientists and resource managers are using SWAT models to answer land management questions and to inform nonpoint source pollution control decisions in agricultural watersheds such as Western Lake Erie, Green Bay, and Saginaw Bay.

The workshop included presentations from several individuals/groups working with SWAT models, and breakout discussion sessions focused on major SWAT challenges and improvements. Presentations and breakout session topics are posted below.


Session I: SWAT Model Use and Development

Session II: SWAT Applications in Water Center Supported Research

Session III: Further SWAT Applications in Great Lakes Watersheds

Breakout Session Topics

  • Phosphorus (especially SRP) fate and modeling within SWAT and nutrient transport through tile drainage systems
  • Comparing models: model outputs, set-up, inputs
  • Modeling nutrient and soils erosion and transport within the stream/ditch network within SWAT
  • Modeling agricultural BMPs within SWAT (including considerations of spatial scale)
  • Challenges in coupling or linking model (e.g., SWAT models with climate/lake/ecosystem models)

Next Steps

Other workshop materials, including a proceedings document and a prioritized list of recommendations developed by participants, are being posted as they become available.
