qgis-epanet's Introduction

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 :

https://vimeo.com/87754967

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)

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.

qgis-epanet's Issues

Bug: The timeplot works only when layers name are standard

For the simplest example, tank emptying in a pipe, if the layers name are other than junctions, tanks & pipes, the simulation runs by matching in the algorithm options which is who.
However, if the layer names are not standard, the timeplot graph doesn't work.

PROBLEM with qgis-epanet aplication

Hi,
I new user with qgis-epanet application.
The last day I have some problem with the application under windows8 and ubuntu 14.
The first problem was when I run the simulation in qgis return to me the next message...
Algorithm Simulate flow in drinking water network starting...

The next, I decided to use the example "simple_network" and qgis returned to me the same message.

Well, now I tried to rewrite the code and qgis return the new error message:

Algorithm Simulate flow in drinking water network starting...
No simulation named 'Epanet Simulation' in TIMES

I changed the name but I don't have found any error and possible solution.

Thank for see this message,
I wait the ask for my problem.

Best regards community!

[Error 5] Access is denied See log for more details

Running the tool on the test data and getting an error;

Algorithm Simulate flow in drinking water network starting...
running simulation

[Error 5] Access is denied See log for more details

I have EPANET2 installed and the plugin set to my install directory for EPANET2 where the .exe file resides. I don't see a commandline tool in this directory, or anywhere on my PC. This might be the issue but the only EPANET tool I could find was here...
https://www.epa.gov/water-research/epanet#downloads

Is there something else I am too have installed? The link on the readme takes me to a 404 error.
Thanks
Tyler

Create view from QWat model

A draft sql script is already there but not functional at the moment.

support spanish version of epanet

Output for the simple example has been added in change-set 7f9cf64

Integrate GHydraulics samples

There are apparently 3 models as examples in GHydraulics.
http://epanet.de/ghydraulics/index.html.en

It would be great to have them in qgis-epanet as well.

Providing them as a separate data sample downloadable package could be interesting if the files are big (considering the plugin size limits on plugins.qgis.org )

Add WNTR support?

A recently opensourced EPA software that extends the EPAnet functionality and is written in python:
https://github.com/USEPA/WNTR

Add link to this place to plugin's metadata.txt

Link to a bugtracker is now mandatory for plugins.

Input Error 201

I keep getting this error when I try run the imported Coimbra sample files to Postgis.
I can't see the difference between Postgis and spatiallite data.
Am I missing something?
