Water Simulation Packages (WSP)

HEC-RAS allows you to perform one-dimensional steady and unsteady flow calculations. Sediment Transport computations and Water Quality analysis will be added in future versions.

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

EPANET is a Windows 95/98/NT program that performs extended period simulation of hydraulic and water-quality behavior within pressurized pipe networks. A network can consist of pipes, nodes (pipe junctions), pumps, valves and storage tanks or reservoirs. EPANET tracks the flow of water in each pipe, the pressure at each node, the height of water in each tank, and the concentration of a chemical species throughout the network during a simulation period comprised of multiple time steps. In addition to chemical species, water age and source tracing can also be simulated.

The Windows version of EPANET provides an integrated environment for editing network input data, running hydraulic and water quality simulations, and viewing the results in a variety of formats. These include color-coded network maps, data tables, time series graphs, and contour plots.

EPANET was developed by the Water Supply and Water Resources Division (formerly the Drinking Water Research Division) of the U.S. Environmental Protection Agency’s National Risk Management Research Laboratory. It is public domain software that may be freely copied and distributed.

FireFlow is a Freeware, EPANET based tool, which will calculate the available flow at network junctions while a minimal pressure is kept at demand junctions. FireFlow can run in a “Steady State” mode or perform an “Extended Period Simulation” (EPS). Using the EPS mode you can find how long can a specified flow be delivered? Or, what is the maximal flow that can be delivered for a specified period?
