Using WinSLAMM Meeting Urban Stormwater Management Goals See upcoming dates

Course Overview

This hands-on, computer-based course will demonstrate how the latest WinSLAMM software incorporates long-term local rain data along with soils, land use, source area, and other local watershed factors to quantify pollutant sources in complex urban watersheds.

Learn how to use WinSLAMM to:

  • calculate pollutant loads and runoff volumes, the cost of stormwater control practices, and runoff volume impacts from porous pavement
  • analyze outlet options for wet detention ponds, street dirt washoff and catch basin cleaning, and whether biofilters meet regulatory requirements
  • estimate the effectiveness of filter strips, rain barrels and cisterns, hydrodynamic treatment devices, stormwater media filters, and grass swale drainage systems.

Who Should Attend?

  • Design engineers
  • Architects
  • Contractors
  • Developers
  • Regulators 
  • Reviewers 
  • Regional planning staff
  • City or county staff with stormwater management responsibilities
