Some of you may have seen it already, but it seems to be sort of languishing in obscurity. I didn't see any mention of it in the normal QGIS community places; only in a number of academic papers. It originally comes from here: http://www.pihm.psu.edu/pihmgis_home.html Their binary and source packages are both very messy and include a very old version of QGIS, and the source package for some reason isn't the latest version of the plugin. I *think* the original authors may have abandoned the QGIS plugin in favour of a web-based system. However, there is a public fork of the latest version here, including a windows and a linux binary: https://github.com/mlt/PIHM/wiki I guess he must have contacted the authors to obtain the source. He has cleaned up the file tree and done some fixes, including so that it builds with msvc, and doesn't violate the GPL. (I wish I'd found this earlier, because I started doing the same thing...) The plugin provides terrain analysis features similar to the TauDEM plugin for Mapwindow and ArcGIS (but without the fully automatic mode): pit removal, stream network and watershed delineation, etc. It also runs the "Penn State Integrated Hydrologic Model", and can produce a number of time series and spatial plots of the results. I recommend using the tutorial (and sample data) available on the web site: http://www.pihm.psu.edu/pihmgis_documents.html The built-in help documentation is the same, but is missing the pictures! This might also be useful: http://www.pihm.psu.edu/Downloads/Doc/pihm_input_file_format.pdf There are a number of interesting papers which mention it, and often have a short description of QGIS itself, e.g.: Community Hydrologic Model: Structure http://cuahsi.org/chymp/thurs/RMaxwell.ppt Multiphysics Modeling Implications for Environmental Observatories http://cuahsi.org/chymp/wed-am/CDuffy.pdf Model-Data Integration Framework: Watershed Reanalysis at the Susquehanna - Shale Hills Critical Zone Observatory http://www.cuahsi.org/chymp/20110315/Presentation_CHyMP_2011_GBhatt_mode ldata.pdf An Object Oriented Shared Data Model for GIS and Distributed Hydrologic Models http://www.personal.psu.edu/muk139/KumarEtAl_DataModel_IJGIS.pdf The Role of Physical, Numerical and Data Coupling in a Mesoscale Watershed Model http://www.personal.psu.edu/muk139/Mukesh_PIHM_Dec01_2009.pdf And this one doesn't mention it, but I know there are some people here interested in parallelization ;) : Domain Partitioning for Implementation of Large Scale Integrated Hydrologic Models on Parallel Processors http://www.personal.psu.edu/muk139/Mukesh_DP_Dec01_2009.pdf Regards, Alister _______________________________________________ Qgis-community-team mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-community-team
