The purpose of this notebook is to illustrate the use of the Terrain Analysis Using Digital Elevation Models (TauDEM) software for Watershed Delineation and calculation of Height above the nearest Drainage (HAND), using data from HydroShare and saving results back to HydroShare. TauDEM is a free and open source set of Digital Elevation Model (DEM) tools for watershed delineation and extraction and analysis of hydrologic information from topography as represented by DEM.
This notebook is intended as a brief introduction to guide a reader through the steps of running some of the more important functions required to delineate a stream network using TauDEM. Once you recognize the pattern from this, you can refer to documentation on the use of each TauDEM function found at http://hydrology.usu.edu/taudem/taudem5/documentation.html, and construct other analyses to meet your needs.
To use the Jupyter Notebook click on the "Open With" blue bottom at the top right of this page and choose "Jupyter". Then run the first few cells on the Welcome page. These cells establish a secure connection to the HydroShare and get the main notebook and the inputs to run the example. When the main code and the inputs are retrieved, you can click on "TauDEM.ipynb" to see the code and run it. The Jupyter Notebook also has steps to save all the inputs, outputs, and the main code into a new resource.
