Similar to the RiverTools page this should have misc. tips for getting TopoFlow running.

To run Topoflow you'll need from RiverTools:

  • *.rti file from your DEM
  • *flow.rtg flow grid
  • *order.rtg Horton Strahler order grid
  • *area.rtg upstream areas grid
  • *slope.rtg downstream slopes grid

Then, with TopoFlow you'll need to create from the Preprocessing menu:

  • Channel Geometry Grids. Select Parameterize with H-S order grid and then set the Manning's N for the channels, the bed widths and the bank angle.


Also from RiverTools, use the Value Zoom to find the basin outlet row & column.
