Explain value 100 in eroding DEM expression
Provide reasoning for the value 100 in Compute new DEM with erosion carved-in in the Erosion modeling (hydrology_erosion.html) assignment.
r.mapcalc "elev_erodedb_1m = elev_lid792_1m-(soillossbare_1m/100.)"
Additionally, consider changing the value.
This was an ad hoc value purely for visualization purposes- feel free to change it, the proper value along with the units may be in the related pdf or in the erosion paper with Michael Barton (Isaac spent some time figuring it out for different conditions)
