It stands for Hydrologic Engineering Center's Data Storage System Visual Utility Engine-HEC-DSSVue. It is a Java-based visual utilities program that allows users to plot, tabulate, edit, and manipulate data in a HEC-DSS database file. The graphics produced by HEC-DSSVue are highly customizable and incorporate over sixty mathematical functions. Along with these functions, HEC-DSSVue provides several utility functions that provide a means to enter data sets into a HEC-DSS database, rename data set names, copy data sets to other HEC-DSS database files, and delete data sets.

It is the Hydrologic Engineering Center's - Hydrologic Modeling System (HEC-HMS) and 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. Advanced capabilities are also provided for gridded runoff simulation using the linear quasi-distributed runoff transform (ModClark). Supplemental analysis tools are provided for model optimization, forecasting streamflow, depth-area reduction, assessing model uncertainty, erosion and sediment transport, and water quality.Read More
