1- Input Data

he dam-building beaver capacity model requires:

  • A drainage network layer
  • Hydrography data tied to that layer
  • Vegetation type raster data
  • Digital Elevation Model (DEM)
  • Baseflow information throughout drainage network
  • Highflow information throughout drainage network

Existing, readily and freely available GIS datasets from GIS data clearinghouses can be used as model inputs. For the Utah statewide run, we used:


  • Landfire for Vegetation Type raster data
    • Download both Us_140evt (existing vegetation type) and us_140bps (potential vegetation type)

    • us_130 can be used if 140 is not yet available for your study area 


Note: The potential vegetation layer (biophysical settings (BpS)) represents the vegetation that may have been dominant on the landscape prior to Euro-American settlement and is based on both the current biophysical environment and an approximation of the historical disturbance regime. 




The potential conflict inference system requires the following layers:
  • Roads 
  • Railroads 
  • Canals (can be extracted from NHD Flowline layer using FCODEs 33600, 33601, and 33603)
  • Land use raster (can use landfire EVT layer for this)

For the Utah statewide run, we obtained some of this data from the Utah AGRC Mapping Portal.


Note: These data or similar data must be captured before proceeding on to Step 2.
