Hydrologic Engineering Center

The software simulates reservoir operations for flood management, low flow augmentation and water supply for planning studies, detailed reservoir regulation plan investigations, and real-time decision support.

This software allows users to perform statistical analyses of hydrologic data.

Using the software involves two main steps, defining hydrologic conditions or "states" and creating flow recommendations.

The Hydrologic Modeling System (HEC-HMS) is designed to simulate the complete hydrologic processes of dendritic watershed system.

HEC-FDA is designed to assist USACE study members in using risk analysis procedures for formulating and evaluating flood risk management measures (EM 1110-2-1619, ER 1105-2-101).

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.

HEC-DSSVue is a Java-based visual utilities program that allows users to plot, tabulate, edit, and manipulate data in a HEC-DSS database file.

The Hydrologic Engineering Center's River Analysis System (or simply HEC-RAS) is river water modeling software.

HEC-MetVue facilitates viewing and manipulation of meteorological datasets as well as performing a variety of computations and analyses, including temporal and spatial aggregation of datasets and areal average computations.

HEC-EFM Plotter is designed to help users view, navigate, and interpret output generated by HEC-EFM.
