Abstract

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
