Water Simulation

Update: following a comment by Joaquim Sousa, one of the developers of WaterNetGen, I have updated the post since it seems I made a mistake and didn’t use the right settings for the SA method – sorry. A few months ago, researchers from Coimbra (Portugal) released the WaterNetGen program. WaterNetGen is a free EPANet extension to automatically [...]

Baoyu Zhuang added a few functions to the EPANet GUI to allow more options while exporting a map to the DXF format. The USEPA version of EPANet allows the user to export a map to DXF using the File->Export->Map form: This export function will save a DXF file containing the nodes and links of the [...]

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 [...]

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 [...]

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, [...]

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, [...]

The nofdp IDSS (Nature Oriented Flood Damage Prevention, Information and Decision Support System) is an open source application for the interactive development of flood risk strategies and 1D hydrodynamic flood simulation. Additionalֲ modules for ecological and spatial analysis, multi criteria evaluation, flood risk maps, flood frequency, flood duration and communication are included. watch video, download source [...]

Just a few days after posting about EPANET-BAM, Professor Choi sent a link to his AZRED program which simulates mixing at network’s fittings. This work was presented at WDSA 2008ֲ and available online [Development of a Comprehensive Solute Mixing Model (AZRED) at Junctions - pdf]. Abstract: Municipal water distribution networks consist of numerous cross-, tee-, and [...]

Armando Barreto over at Zonum Solutions is looking for beta-testers for his new release – epa2kmz. From Zonums Solutions web site: Epa2kmz transforms NET Files to KMZ format. It allows to visualize Epanet projects in Google Earth, using the GE imagery as background. Epa2kmz can transform the Network Map or the Network Map and the [...]

Armando Barreto, a student at the University of Arizona, wrote me about his new free tool will extract geometric data contained in ESRI-shape files into EPANet INP files. shp2epa was designed with an interface similar to dxf2epa for a familiar feeling for the user.
