QGIS epanet plugin

Extends processing framework to models the hydraulic and water quality behavior of water distribution piping systems

This plugin lets you model hydraulic network for water and run simulations to get water pressure informations and more.

See a demo screencast here :

Requirements

You need :

• A working version of Epanet (english version mandatory)
• QGIS > 2.0
• The QGIS Processing framework
• Python module matplotlib

Installation

You need to have epanet as a command line tool for the plugin to work.

Install Epanet for Windows

Download and run https://www.epa.gov/sites/production/files/2014-06/en2setup_0.exe

Compile Epanet for linux

Download Epanet sources from http://www2.epa.gov/sites/production/files/2014-06/en2source.zip

For linux:

mkdir epanet
cd epanet
wget http://www2.epa.gov/sites/production/files/2014-06/en2source.zip
unzip en2source.zip
unzip -n epanet2.zip 
unzip -n makefiles.ZIP
unzip -n GNU_EXE.ZIP

Open the file epanet.c, comment out the line

#define DLL

and uncomment the line

#define CLE

The file should look afterwards like:

#define CLE     /* Compile as a command line executable */
//#define SOL     /* Compile as a shared object library */
//#define DLL       /* Compile as a Windows DLL */

Open the file Makefile and replace the line

cc -o epanet2 -lm $(objs)

by

cc -o epanet2 $(objs) -lm 

Then run:

make

Install the plugin

Simply put this directory in the plugin directory. On linux:

cd ~/.qgis2/python/plugins
git clone https://github.com/Oslandia/qgis-epanet.git

You then need to run QGIS, install the processing plugin and configure the path to the epanet executable in QGIS menu Processsing->Options and configuration.

Note: On Windows, choose epanet2d.exe.

Testing

The file simple_network.zip contains an example of a tank emptying on a pipe. Unzip the directory en follow intructions in simple_network/README.md

Notes

This plugin has been tested on real data on a real use case. This use case cannot be made publicly available.

We are currently looking for a use case with data that can be published alongside the code.
