<div><div>Hi Francesco,<br><br></div>I have looked into this and wine is not needed. However, there are still some hurdles. I will list the steps so that it is as straightforward as can be (or as much as it can be from me  :-) :<br>



<br></div>1. Install the GHydraulics plugin. This plugin actually contains command line binaries of epanet for Linux, Win, and Mac; though, it is actually against plugin policy to distribute pre-compiled binaries with plugins through the official QGIS repository. Nonetheless, it is a good thing for you and other Mac users.  :-)<br>



<br></div>This means GHydraulics actually works right out-of-the-box. There is a bug in one of the sources, though.<br><br></div>In ~/.qgis2/python/plugins/ghydraulic/GHydraulicsModelMaker.py:<br><br></div>Change ALL instances of<br>



  QgsMapLayerRegistry().instance().mapLayers()<br>to<br>  QgsMapLayerRegistry.instance().mapLayers()<br><br></div><div>I'll be reporting this upstream to <a href="http://epanet.de/" target="_blank">http://epanet.de/</a><br>


<br></div>
<div>NOTE: some of the reporting from the plugin is actually sent to the Log Messages Panel. Choose 'View -> Panels -> Log Messages' to ensure it is visible.<br><br></div><div>See also:<br><a href="http://epanet.de/ghydraulics/index.html" target="_blank">http://epanet.de/ghydraulics/index.html</a><br>

<br></div><div>3. I think I will add epanet command line utilities to OSGeo4Mac, so this is simpler to set up.<br><br></div><div><div class="gmail_extra"><br></div><div class="gmail_extra">Regards,<br clear="all">

Once the hydraulic model and simulation parameters are loaded in QGIS, the simulation can be launched through the<b>Processing</b> toolbox. The plugin uses the standalone command line interface of EPANET (CLI) which path needs to be specified in processing Options and configuration.</div>
