HEC-HMS 4.5 is now available!

The Hydrologic Modeling System (HEC-HMS) is designed to simulate the complete hydrologic processes of dendritic watershed systems. The software includes many traditional hydrologic analysis procedures such as event infiltration, unit hydrographs, and hydrologic routing. HEC-HMS also includes procedures necessary for continuous simulation including evapo-transpiration, snowmelt, and soil moisture accounting.

HEC-FIA 3.1 is now available!

The HEC-FIA software enables users to calculate flood damage in terms of direct and indirect economic, agricultural and life loss estimates for a single flood event. The analysis period is the duration of a singel flood event. The software calculates agricultural damage and urban damage for use after an event and summarizes the results in reports. HEC-FIA can also look at dam failure events and evaluate the consequences to support risk assessments for dams. HEC-FIA uses Simplified LIFESim to evaluate the impacts to human life.

HEC-GeoFDA 1.0 is now available!

The Hydrologic Engineering Center's Geospatial Preprocessor for Flood Damage Reduction Analysis (HEC-GeoFDA) software is a geospatial preprocessor for the HEC-FDA software. It facilitates many of the geospatial tasks performed by project delivery teams in support of flood risk management projects. Among its features are abilities to create, edit or load geospatially referenced: terrain data, stream alignments, one and two dimensional gridded hydraulic data, and impact area polygons, structure inventories and more. These data are processed within the software to produce files that can be imported directly into supported versions of the HEC-FDA software.
