Model My Watershed®

About the Tool

Model My Watershed is a watershed-modeling web app that enables citizens, conservation practitioners, municipal decision-makers, educators, and students to

  • Analyze real land use and soil data in their neighborhoods and watersheds
  • Model stormwater runoff and water-quality impacts using professional-grade models
  • Compare how different conservation or development scenarios could modify runoff and water quality

The Runoff Simulation (formerly known as the Micro Site Storm Runoff Model) is an animated version of the Site Storm Model package of Model My Watershed. It allows users to learn how land use and soil together determine whether rainfall infiltrates into the soil, runs off into streams or is evaporated and transpired by plants.

Our vision is to provide an easy-to-use professional-grade modeling package to inform land-use decisions, support conservation practices, and enhance watershed education.
