Wave Pattern


The Terrain Anlysis Using Digital Elevation Models (TauDEM) is a suite of tools developed by David Tarboton at Utah State University's Hydrology Research Group. The Riverscapes compliant, Production Grade TauDEM, utilizes some of the useful TauDEM algorithms, packaging inputs and outputs into a Riverscapes project that can be accessed as a product of its own, or used as inputs to other Riverscapes tools.

Riverscapes TauDEM projects take an input DEM and a channel and produce the following outputs using TauDEM algorithms:

  • Pit-filled DEM
  • D-infinity flow direction raster
  • D-infinity contributing area raster
  • Topographic Wetness Index (TWI)
  • Height Above Nearest Drainage (HAND) raster
  • D-infinity slope raster (percent)
  • Additionally, produces a D-8 slope raster (degrees) using GDAL.
