The Hydrologic Engineering Center Flood Impact Analysis (HEC-FIA) software, Version 2.2, analyzes the consequences from a flood event. It calculates damages to structures and contents, losses to agriculture, and estimates the potential for life loss. HEC-FIA can also assist Corps Planning studies by looking at single events deterministically to support the OSE account with Life Loss and population at risk, or through helping to determine the impacts to agriculture for typical events for the study region. It should be noted that HEC-FIA can only be used to compute annual benefits across the full range of potential flood events, and in compliance with Corps policies regarding risk and uncertainty analysis, when used in conjunction with programs like HEC-WAT with the FRA compute option, DAM-RAE, or @Risk. HEC-FIA is typically used to perform dam and levee failure scenario analysis to support consequence estimates to determine the risk posed or prevented by Corps Projects.

This site offers a location to download the HEC-FIA software, along with user, guidance on general applications, sample workshops, and assists with the support services HEC provides to its customers and partners. Please feel free to download the software, ask for assistance, suggest improvements, and report bugs. The diverse experiences of modelers provide far more insights into the application of the program than the software developers can realize on their own, so both positive and negative feedback and suggestions are welcome. Direct technical support by HEC is limited to Corps of Engineers staff members and organizations with a support agreement. Please review our Support Policy page for details.
