This fact sheet introduces DSS-WISE HCOM, a FEMA-supported analytical module for assessing the human consequences of dam-break floods. The tool provides automated mapping of flood hazard risk zones, identifies potentially lethal flood zones for different population groups, and analyzes people at risk using census and gridded population data. DSS-WISE HCOM outputs include geospatial files, reports, and tables to support emergency action planning, preparedness, and evacuation planning for dam safety professionals and agencies.
