GIS Tools to Support Stormwater Management

Stormwater 2003 Conference
Fox Wolf Watershed Alliance
Green Bay, Wisconsin
March 6, 2003

This all-day workshop conducted by David Hart and Brea Lemke of the University of Wisconsin-Madison explored a range of GIS tools to support stormwater management. These tools included L-THIA (Long-Term Hydrologic Impact Assessment) developed by Purdue University; BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) developed by the Environmental Protection Agency; ISAT (Impervious Surface Analysis Tool) developed by the NOAA Coastal Services Center; and SLAMM (Source Loading and Management Model) developed by Robert Pitt and John Voorhees. The workshop ended with a demonstration of GIS interoperability to support floodplain management in Wisconsin.
