1. Input Data Capture

The 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_120evt (existing vegetation type) and us_120bps (potential vegetation type) 

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 
  • Culverts
  • Stream Crossings (User generated point file of road/stream intersections) 
  • Canals
  • Land use
  • Landownership 

For the Utah statewide run, we obtained all of the above data from the Utah AGRC Mapping Portal.


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

Matlab and FIS Files

The matlab and FIS files for the beaver dam capacity, conflict potential and conservation and restoration models are provided at the following link: Matlab_FIS.zip. This zipfile also contains an input .csv table (Matlab_Input_Formatted_Empty_CSV.csv) to be used when running the models.
