TauDEM for Processing
Integrates TauDEM into QGIS Processing framework.
TauDEM (Terrain analysis using Digital Elevation Models) is a suite of tools for the extraction and analysis of hydrologic information from topography as represented by a DEM.
Plugin published in my repository.
Once installed and enabled, the TauDEM for Processing plugin is registered as a Processing provider. You will need to enable and (optionally) configure the provider before using its tools. Open QGIS options from the menu "Settings → Options" and go to the "Processing" tab. Expand "Providers" group and find "TauDEM" sub-group; there you will find all settings related to the TauDEM provider.
Check the "Activate" checkbox to enable provider and add its tools to the Processing toolbox. Unchecking this checkbox will disable provider.
Also, you will need to tell the plugin where to find the MPICH/OpenMPI executable, as well as the TauDEM tools executables. If these settings are not set, the plugin will assume that their locations were already added to the
PATH environment variable and the tools accessible by name. Finally, adjust the number of processors which will be used by MPICH/OpenMPI.
The "Log commands output" option can be used to save all messages printed by TauDEM tools during execution, to the QGIS log.
When done, save settings by pressing "OK".
If the provider is activated, it will add its algorithms to the Processing toolbox under the "TauDEM" group.
These tools can be used as any other Processing algorithm: as a standalone tool, in batch processes, in models and scripts. Please refer to the QGIS User Guide to learn how to use Processing tools.
TauDEM tools help can be found at their homepage. Also you may want to read this article showing how to perform some hydrology analysis tasks with TauDEM.
