<br><br>Hi everyone,<br>
I just want to let you know about a QGIS plugin for integrated catchment<br>
modelling. Some of you may have seen it already, but it seems to be<br>
sort of languishing in obscurity. I didn't see any mention of it in the<br>
normal QGIS community places; only in a number of academic papers.<br>
<br>
It originally comes from here:<br>
<a href="http://www.pihm.psu.edu/pihmgis_home.html" target="_blank">http://www.pihm.psu.edu/pihmgis_home.html</a><br>
Their binary and source packages are both very messy and include a very<br>
old version of QGIS, and the source package for some reason isn't the<br>
latest version of the plugin.<br>
I *think* the original authors may have abandoned the QGIS plugin in<br>
favour of a web-based system.<br>
However, there is a public fork of the latest version here, including a<br>
windows and a linux binary:<br>
<a href="https://github.com/mlt/PIHM/wiki" target="_blank">https://github.com/mlt/PIHM/wiki</a><br>
I guess he must have contacted the authors to obtain the source. He has<br>
cleaned up the file tree and done some fixes, including so that it<br>
builds with msvc, and doesn't violate the GPL. (I wish I'd found this<br>
earlier, because I started doing the same thing...)<br>
<br>
The plugin provides terrain analysis features similar to the TauDEM<br>
plugin for Mapwindow and ArcGIS (but without the fully automatic mode):<br>
pit removal, stream network and watershed delineation, etc.<br>
It also runs the "Penn State Integrated Hydrologic Model", and can<br>
produce a number of time series and spatial plots of the results.<br>
<br>
I recommend using the tutorial (and sample data) available on the web<br>
site:<br>
<a href="http://www.pihm.psu.edu/pihmgis_documents.html" target="_blank">http://www.pihm.psu.edu/pihmgis_documents.html</a><br>
The built-in help documentation is the same, but is missing the<br>
pictures!<br>
This might also be useful:<br>

<br>
There are a number of interesting papers which mention it, and often<br>
have a short description of QGIS itself, e.g.:<br>
<br>
Community Hydrologic Model: Structure<br>
<a href="http://cuahsi.org/chymp/thurs/RMaxwell.ppt" target="_blank">http://cuahsi.org/chymp/thurs/RMaxwell.ppt</a><br>

<br>
And this one doesn't mention it, but I know there are some people here<br>
interested in parallelization ;) :<br>
