HEC-RAS - impressive, professional and very useful tool that helps you to perform one-dimensional steady flow, unsteady flow etc.

The Hydrologic Modeling System (HEC-HMS) is designed to simulate the precipitation-runoff processes of dendritic watershed systems. It is designed to be applicable in a wide range of geographic areas for solving the widest possible range of problems. This includes large river basin water supply and flood hydrology, and small urban or natural watershed runoff.
|
|
The program allows users to visualize spatial information, document watershed characteristics, perform spatial analysis, and delineate subbasins and streams. Working with HEC-GeoHMS through its interfaces, menus, tools, buttons, and context-sensitive online help allows the user to expediently create hydrologic inputs for HEC-HMS.

HEC-SSP is an integrated system of software, designed for interactive use in a multi-tasking environment. The system is comprised of a graphical user interface (GUI), separate statistical analysis components, data storage and management capabilities, mapping, graphics, and reporting tools.

The Flood Damage Reduction Analysis (HEC-FDA) software is designed to assist US Army Corps of Engineers (USACE) study team members in using risk analysis methods for flood risk management studies as required by USACE guidance - ER 1105-2-101.
The approach explicitly incorporates descriptions of uncertainty of key parameters and functions into project benefit and performance analyses.

The Regime Prescription Tool (HEC-RPT) is designed to facilitate entry, viewing, and documentation of flow recommendations in real-time, public settings. HEC-RPT seeks to improve 1) communications in group settings by allowing real-time recording and plotting of the recommendations as they are developed and 2) the recommendations produced.

|
HEC-GridUtil is designed to provide viewing, processing, and analysis capabilities for gridded data sets stored in HEC-DSS format (Hydrologic Engineering Center's Data Storage System). Sequences of grids typically approximate the variation through space of a quantity measured varying through fixed-intervals of time at fixed locations.
|
|
HEC-EFM analyses involve: 1) statistical analyses of relationships between hydrology and ecology, 2) hydraulic modeling, and 3) use of Geographic Information Systems (GIS) to display results and other relevant spatial data.
Most features in the main interface of HEC-EFM focus on the first step in this process (statistical analyses). The main interface has four tabs.

|
The HEC-DSS Excel Data Exchange Add-In is a Visual Basic Application for retrieving and storing both regular-interval time series and paired data directly from Excel to an HEC-DSS database file. Data sets to retrieve are selected from a catalog listing directly available from Excel.
|
|
HEC-EFM Plotter is designed to help users view, navigate, and interpret output generated by HEC-EFM. Available outputs are automatically imported as a series of “Standard Plots” for the flow regimes and relationships being analyzed in HEC-EFM.
“Custom Plots” can be added to compare results for multiple relationships or flow regimes.
