Stormwater Pollution Modeling for LID, TMDL, and Retrofitting Analyses— An Overview of WinSLAMM
Location:  Bellevue, WA
Time:  8:30 AM - 4:00 PM 
Forester Media

Bellevue, WA

This course requires all attendees to have a laptop computer with them for use during the course. If you plan on attending with someone from your organization, you may also share a computer.

Attendees with their own laptop may use a temporary license of the model during the course. WinSLAMM can be run on a PC with Windows XP, Vista, or Windows 7 and will need a CD drive and/or a USB port to load the program. You will need administrative privileges for the computer if the program is not pre-loaded.

This hands-on, computer-based course will demonstrate how to use WinSLAMM to utilize source area stormwater controls to maintain or create a hydrologically functional landscape that mimics natural watersheds’ hydrologic functions (volume, frequency, recharge, and discharge). By integrating source area controls into site design, you can approach the pre-development site stability to retain water and pollutants.

You will learn to:
• Quantify pollutant sources in complex urban watersheds
• Predict the performance and impact of many interacting development and control options
• Calculate pollutant loads and runoff volumes from various structural and non-structural management scenarios
• Estimate and compare the costs of stormwater control practices

About WinSLAMM
WinSLAMM is a Windows-based, continuous simulation computer program, that helps water resources professionals make effective decisions by modeling the stormwater impacts of new or existing developments and evaluating the benefits of various control measures. The WinSLAMM model has been used for over 15 years to calculate urban stormwater runoff volume, pollution loads, and assess a wide range of management measures. The model enables accurate planning-level and design-level analyses. Wisconsin’s Department of Natural Resources has adopted the model for regulatory compliance purposes. The WinSLAMM batch processor provides data for decision makers to select the most cost-effective alternative stormwater control practices. WinSLAMM is typically used in continuous simulations of at least one year of local rain events to examine these issues over a wide range of actual site conditions.

The one-day course will cover:
• Modeling terminology and preparing to model WinSLAMM theory and practice
• WinSLAMM model features and navigation
• Base file setup
• Grass swale & filter strip modeling/design
• Biofilter modeling/design
• Analyzing an example LID subdivision development for stormwater volume and TSS loads
