Water Simulation

A colleague wanted to convert an EPANet file to an AutoCAD drawing. After having a few issues with the DXF2EPAutility he found anothe program for this task – EPACAD. EPACAD, by the ITAresearch group over at the Universidad Politecnica de Valencia, is a free software which can converts an AUTOCAD file into an EPANET one. EPACAD is able to [...]

When working with hydraulic models, especially of large networks, the user often face a problem when he wants to compare two versions on the model to see what changes were made. The GeoAdvice Model Comparator by GEOAdviceֲ aims to assist in this task.The program is an Excel Addon (requires Excel 2007) and currently can compare models [...]

ֲ From maplecroft: A new report evaluating the water security of 165 countries has rated the supply of clean, fresh water to the societies and businesses of 10 nations at “extreme risk.” I don’t have access to the full report so I have not read it yet. If you have a copy and can shareֲ it with [...]

WaterIng is a software research program of the Multidisciplinary Group of Fluid Modelling in Valencia (GMMF):ֲ  WaterIng is a software package for water distribution system design and analysis. It offers a multi-objective evolutionary optimization engine based on distributed artificial intelligence to support design and operation decision-making (Agent Swarm Optimization). Improved solutions from both hydraulic and [...]

During the summer of 2009 a large number of water pipe breaks occurred in Los Angeles. Apparently,ֲ  there were 101 blowouts in the summer of 2009 (July, August and September) compared to 42 in 2008, 49 in 2007 and 48 in 2006. As a consequence of the public request for an explanation an independent investigation [...]

Tim Hirrel sent me his new product release info for Tdhnet: 3 new hydraulic network modeling products have been released and are now available for download. These products are the latest releases in the Tdhnet line of hydraulic network software and represent a major breakthrough in the availability of cross platform hydraulic network models. TdhLite, [...]

Online water demand data, published by EPCOR, show that Canadians have invented a new kind of sport – synchronized toilet flushing. It seems that all the TV viewer of the Olympic gold medal hockey game flushed their toilet at the same time during breaks in the game. ֲ  ֲ  via: Pat’s Papers

Following the Battle of the Water Networks (BWN) in 1985 and more recently the Battle of the Water Sensor Networks (BWSN) I’m happy to announce the Battle of the Water Calibration Networks (BWCN): The BWCN calls for teams/individuals from academia, consulting firms, and utilities to propose a calibration methodology and apply it to a real [...]

Oliver Diaz sent me a link to an Excel addon he wrote to convert Excel data to the INP file of EPANet. In addition, it can export excel data to AutoCAD by generating a dxf file. Points with coordinates X, Y, Z from an excel sheet can be exported to a dxf file as points, [...]

A few weeks ago I had a conversation with an American colleague regarding the maximum water pressure at home connections. He was amazed to hear that the water pressure at my house is about 9 bars. To show him I was not mistaken I connected a pressure gauge in my garden and took a few [...]
