Water Simulation Packages (WSP)

See the new look of StormwaterAuthority.org

StormwaterAuthority is a place where specifying engineers, contractors, developers, site owners and regulators can learn and share information. It’s a place to research best management practices and regulations. A place with the latest news on stormwater management and treatment. A place that helps you implement the best plan, reduce short- and long-term costs, and make informed business decisions.

MWH Soft released InfoWater UDF, a solution for unidirectional flushing of drinking water distribution systems. InfoWater UDF delivers helps in managing the systematic flushing of water distribution systems to remove stagnant water along with mineral and sediment deposits that accumulate over time - restoring hydraulic capacity and improving water quality.

The hydraulic carrying capacity of pipes deteriorates with age, proportionate to the corrosive nature of the water and surrounding soils. Precipitation, microbiological activity and corrosion may all form deposits on the pipe walls. These accumulations increase hydraulic roughness and reduce the cross-sectional area and hydraulic carrying capacity of the mains. A loss in carrying capacity can lead to low pressures and the inability to deliver fire flows, especially during high demand periods. Slow-moving water can also result in a loss of chlorine residuals at stagnant spots, creating a public health risk. Problems associated with water quality degradation are particularly acute in dead-end lines and low-demand portions of water distribution systems.

From BOSS International:

BOSS International has recently released RiverCAD® XP after 5 years of development. RiverCAD XP is a sophisticated river modeling software with a built-in CAD engine that completely supports the latest versions of HEC-RAS and HEC-2. Its slick GUI interface is intuitive. RiverCAD XP works within AutoCAD versions 2000 through 2006.

RiverCAD XP makes it easier than ever before to compute water surface profiles for modeling bridges, culverts, spillways, levees, bridge scour, floodway delineation, floodplain reclamation, stream diversions, channel improvements, and split flows. A stand-alone version will be available shortly.

Following the Waterhammer in pipelines program a new item by the same author is available. The new program is called Pump Designer. Here is a few words from the author:

By means of this program you will have a aid to design a pump station for a simple pipeline system (1 line). You will can introduce the flow parameters, select the pipe type, select a suction and a discharge pipe and you will can also plot the system and pump curve for the selection of the pump size. The program calculates also the friction and local loss, the cavitation and the pump power.

You will can simulate with ease, for example, different flow rates, velocities, types of pipe materials, pipe diameters as well as also to plot your proposed pump curve.
