The DOD/DISA STIG Viewer tool provides the capability to view one or more XCCDF (Extensible Configuration Checklist Description Format) formatted STIGs in an easy-to-navigate, human-readable format.

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.

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.
