SDR: erodibility factor


Which value for Erodibility factor (K) is recommended to water bodies pixels into Factor K raster for SDR model ?

    Hi there, 
    Water bodies do not produce sediment so I'd recommend setting the K factor to 0.
  • Hello! I am using The FAO DSWM (Digital Soil Map of the World) to derive K factor for SDR model, but there are no values for  "DS = Dunes or shifting sands". What would You recommend? Thank You in advance!

    Sorry I have no experience with this. I'd recommend looking for scientific literature on sediment modeling in the region.
