Water Simulation Packages (WSP)

CEDRA-AVwaterTM enables the engineer to define the geometric configuration, establish the materials inventory of a water distribution network, introduce supply and demand loads, perform analyses and display pertinent results in graphic and/or tabular format. Storage tanks, pressure regulating, sustaining and open/close valves, pumps, meters, etc. can be included in the water distribution model. Extended period simulations which adjust liquid levels in tanks over a user-specified simulation period may be modeled. AVwater users can perform Fire Flow analyses with node and pipe summary tables being created facilitating the system adequacy determination, as well as, Dynamic Water Quality modeling which tracks the fate of a dissolved substance flowing through the network over time. CEDRA AVwaterTM offers the engineer an ArcView® GIS and ArcGIS® interface to (a) the University of Kentucky’s KYPIPETM modeler and (b) the U.S. Environmental Protection Agency’s EPANETTM Version 1 and Version 2 modelers, thereby integrating modeling and GIS technology.

The DC Water Design Extension is a FREE Extension to ESRI’s ArcView GIS software. The DC Water Design Extension integrates the EPANET 2.00 hydraulic modeling software with ArcView. It allows to store, edit and retrieve EPANET hydraulic models including all options in ArcView. Also it’s possible to run the EPANET hydraulic analysis from ArcView and load the results into the GIS.

The DC Water Design Extension can be obtained from the sourceforge.net website. The sourceforge site offers a multitude of services related to the DC Water Design Extension, including:

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.

Epanet 2

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?
