• This tutorial provides instructions on how to how a groundwater component to you Watershed Simulation Model.

Prerequisits

• Watershed analysis saved with all data
• Working Watershed simulation model (See Tarsier Tutorial: Watershed simulation using the Marmoset Model)

Adding aquifer Information to your Network Data

• Open Aquifer Tab in Watershed Analysis tool
• Click Calc Floodplain
  • Warning: Must have your Net Ptr, HydroDEM, and Stream Raster open in their usee controls.
  • This tool creates a raster covering your floodplain according to your set max flood height
  • Default max flood height it 1 meter. This should be estimated and changed to suit your watershed.
• Click Calc Floodplain Area
  • Warning: Must have your Net Ptr, HydroDEM, and Stream Raster And your floodplain raster open in their usee controls.
  • This too breaks up your floodplain and connects a floodplain area with a corresponding node.
• Click Calc Aquifer From Floodplain
  • Warning, must have your floodplain raster open, and have calculated floodplain area
  • This tool uses a hillslope parameter to estimate triangular aquifer geometry
  • The default hillslope is 15 degrees from horizontal, make a good estimation for your watershed.
  • Warning, a hillslope less then or equal to zero, or greater or equal to ninety will not work properly.

Including GroundWater processes in you Watershed Model

• In Progress....
