The HEC-FIA (Flood Impact Analysis) software package 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.

The Flood Damage Reduction Analysis (HEC-FDA) software provides the capability to perform an integrated hydrologic engineering and economic analysis during the formulation and evaluation of flood risk management plans.
Statistical Software Package (HEC-SSP) developed by the Hydrologic Engineering Center. This software allows you to perform statistical analyses of hydrologic data.
The Hydrologic Modeling System (HEC-HMS) is designed to simulate the complete hydrologic processes of dendritic watershed systems.
HEC-RAS is designed to perform one-dimensional hydraulic calculations for a full network of natural and constructed channels.
The Reservoir System Simulation (HEC-ResSim) software is used to model reservoir operations at one or more reservoirs for a variety of operational goals and constraints.
The Ecosystem Functions Model (HEC-EFM) is designed to help study teams determine ecosystem responses to changes in the flow regime of a river or connected wetland.
