Water Simulation Packages (WSP)

The Organizing Committee of the International Conference on Water and Flood Management (ICWFM) is pleased to invite all interested persons to participate in the Conference to be held in Dhaka, Bangladesh, March 12 to 14, 2007.

The present conference is aimed to make a bridge among the researchers, academicians and professionals with common interest to exchanges their views to address the issues related to water and flood management

From Energy-Solutions:

pipelinestudio is the industry-leading tool for design and off-line simulation of pipeline networks. It features:
* Quick and easy project setup
* Advanced hydraulic models for liquids and gas
* Steady-state and transient simulation

pipelinestudio improves the efficiency and accuracy of offline planning and design simulation through advanced offline simulation techniques for both natural gas and liquid pipelines. Through techniques such as steady-state and transient hydraulic analysis, pipelinestudio delivers a consistently higher quality of business decision, enabling better financial performance. And once pipelinestudio has constructed an offline engineering model of your pipeline network, the same model can be embedded into custom applications to enhance specific business processes and your financial performance overall.

pipelinestudio is flexible enough to consider your pipeline network as a whole and includes variables like demand forecasting and gas nominations. Its familiar Windows graphical interface makes it easy to use and pipelinestudio integrates with GIS and other corporate databases and applications—including other Energy Solutions products.

Use pipelinestudio for:
* Planning, strategically or for facilities
* Analyzing hydraulic characteristics
* Designing pipelines and equipment
* Modeling for predictive purposes
* Simulating situations from existing data

And pipelinestudio can help operators see the effects of operational changes without having to actually go to the control room. By studying the simulated results of proposed operating actions, quality decisions are promoted—realizing bottom-line savings through attractive maintenance savings and opportunity cost avoidance.

BOSS International released two updates:

Multiple River Reaches in RiverCAD XP

RiverCAD XP now fully supports multiple river reaches allowing you to model dendritic river networks. RiverCAD XP fully integrates with LDD and Civil3D software.

RiverCAD XP for AutoCAD is a sophisticated river modeling software that completely automates HEC-RAS and HEC-2 within AutoCAD. Its slick GUI interface is intuitive. RiverCAD XP for AutoCAD works within AutoCAD versions 2000 through 2007. Graphically cut cross sections, generate floodplain maps, automate floodway delineations, compute bridge scour, and more.

Rational, Modified Rational Method, TR-55, TR-20 released in StormNET

StormNET™ now supports Rational, Modified Rational, Santa Barbara Unit Hydrograph, as well as TR-20, TR-55 and SWMM. This new version has completely new advanced graphics, allowing you to easily compare existing versus proposed conditions, and also provides automated pond sizing.

StormNET is the most advanced, powerful, and comprehensive stormwater and wastewater modeling software available for analyzing and designing urban drainage systems, stormwater sewers, and sanitary sewers. StormNET is the only model that combines complex hydrology, hydraulics, and water quality in a completely graphical, easy-to-use interface. Both imperial and metric (SI) units are supported.

StormNET enables accurate routing in complex detention pond situations. In some situations, downstream conditions can cause backwater effects that influence the performance of a detention pond outlet structure. For example, an upstream pond may discharge to another downstream pond that is similar in elevation or influenced by downstream flooding. Such situations can result in a decrease in outlet discharges or flow reversal back into the pond and can be difficult to model properly. StormNET’s interconnected pond routing allows you to easily model these complex situations with confidence.

MathWorks, the makers of Matlab, released a new product that models and simulate hydraulic systems - SimHydraulics.

SimHydraulics extends Simulink with tools for modeling and simulating hydraulic power and control systems. It enables you to describe multidomain systems containing connected hydraulic and mechanical components as physical networks. It provides a representative library of hydraulic components and building blocks that lets you implement other components. SimHydraulics can be used for a variety of automotive, aerospace, defense, and industrial equipment applications, such as modeling automatic transmissions, actuating flight control surfaces, and actuating heavy equipment.

Key Features

• Modeling environment for building hydraulic and hydromechanical systems as physical networks
• More than 75 hydraulic and mechanical components, including pumps, valves, accumulators, and pipelines
• Foundation library of hydraulic building blocks and fundamental mechanical and mathematical elements
• Customizable library of common hydraulic fluids

For more information see SimHydraulics web site.

From Wallingford Software press release:

Wallingford Software announces that the next release of its flagship wastewater network management solution, InfoWorks CS v7.5, adds a powerful new capability for those seeking to accurately model overland urban flooding. This new feature, available this summer, produces flood mapping to represent flood depths and area of spread across the detailed local ground model.

Using a “flood compartment” to define the boundary of the flood mapping, flood levels within the compartments are calculated at manholes. When there is more than one manhole or flood point within a compartment, the flood levels can be calculated between the flood points.

Overland flow pathways can also be examined, showing the routes by which floodwaters access low points such as gardens and car parks. The flood depth is calculated from the flood level relative to the ground surface as represented by an InfoWorks CS ground model.

The display of results can be in both plan and cross-section images. In the plan view, color coding can represent the flood depths across the area. The cross section view shows both the network below the ground, and the image of the flooding above ground level.

For more information see Wallingford Software web site.

Manuel López-Ibáñez, who adapted the EPANET Toolkit version 2.00.10 to GNU/Linux, posted a note that it is possible to run the EPANET GUI in Linux.

This is done be using the GNU/Linux program called Wine HQ that can run Win32 executable files in Linux (and maybe in FreeBSD and SUN’s Solaris).

Please, check Wine documentation for more information.

If you want to discuss this issue please post on the water simulation forum.
