Results from Hydrologic terrain analysis performed on Logan River Basin Digital Elevation model using TauDEM
The input digital elevation model (DEM) is Logan.tif.
The sequence in the script script.py performs a TauDEM analysis that does the following
- Remove pits (by filling them)
- D8 Flow direction
- D8 Contributing area
- Peuker Douglas Valley skeleton
- Weighted D8 contributing area on Peuker Douglas valley skeleton
- Drop analysis to determine objective channel threshold
- Threshold to map stream indicator raster
- Streamnet to produce shapefile of the stream network
Dinfinity analysis for wetness index and height above the nearest drainage (HAND)
- Dinfinity flow direction
- Dinfinity contributing area
- Topographic wetness index
- Distance down to stream in the vertical direction
The file Logan10m.mxd is an ArcGIS map document file for visualizing the results in ArcGIS.
