The Hydrologic Engineering Center Flood Impact Analysis (HEC-FIA) software, Version 3.0 (provisional), is a tool for quantifying the consequences of flood events. New enhancements to HEC-FIA Version 3.0 include evaluation of indirect economic losses from catastrophic flood events and incorporation of uncertainty into consequences computations. For more detail on the new features of HEC-FIA Version 3.0 please visit the HEC-FIA Version 3.0 Features page.

Relevant applications of HEC-FIA Version 3.0 include:
  • Describing the life loss potential to support the U.S. Army Corps of Engineers (USACE) Dam and Levee Safety programs
  • Calculating consequences in real time to support CWMS (Corps Water Management System)
  • Computing benefit to cost ratios with uncertainty in HEC-WAT (Watershed Analysis Tool) with the FRA (flood risk analysis) compute option
  • Supporting calculations for the OSE (Other Social Effects) account for feasibility studies

The HEC-FIA software, User’s Manual on general applications, and sample workshops are available via this webpage. Also, please feel free to download the software, ask for assistance, suggest improvements, and report bugs via this webpage. The diverse experiences of modelers provides far more insights into the application of the software 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 USACE staff members and organizations with a support agreement. Please review our Support Policy page for details.
