Flood Inundation Mapper

Detailed Description

A powerful new tool for flood response and mitigation are digital geospatial flood-inundation maps that show flood water extent and depth on the land surface. Because floods are the leading cause of natural-disaster losses, the U.S. Geological Survey (USGS) is actively involved in the development of flood inundation mapping across the Nation pursuant to its major science strategy goal of reducing the vulnerability of the people and areas most at risk from natural hazards. Flood inundation maps have been created for cities on the map indicated by a black triangle (Iowa City, IA, Marshall, MI, Ottawa, OH, Findlay, OH, Peach Creek, near Atlanta, GA, Albany, GA, Trenton, NJ St. John River, near Fort Kent, ME, and Scituate, MA).
