Integrating Long Term Hydrologic Impact Analysis (L-THIA) and High Impact Targeting (HIT): Web Tools for Watershed Analysis  (Live Webinar)
December 12, 2012

The US Army Corps of Engineers, Purdue University, and Michigan State University Institute for Water Research have collaborated to integrate several of their watershed analysis tools. HIT is an on-line tool that allows users to prioritize erosion and sedimentation reduction conservation efforts in the Great Lakes Basin. Users can compare watersheds by total erosion or sediment load, rates of erosion or sediment loading, and the cost benefit of best management practices (BMPs). Users can also view field-level maps, in 2D and 3D, showing areas at high risk for erosion and sediment loading. L-THIA is an online tool to calculate the hydrologic impact of land use changes, allowing a user to model the impact (by volume and by NPS contaminants) of runoff created by a scenario such as a proposed a new retail development. The goal is to give planners a sense of the impact of various proposals. The newest tools push the analysis down to field-scale simulations.
