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.
