I got the result from SDR model. Show in the table (case I and II) below and I can summaries in soil loss not equal with soil retention plus sediment export.
For common, Soil loss = sediment retention + sediment export.
I try adjust the value of variable such as threshold flow accumulation, Borselli k Parameter, Borselli IC0 parameter and max sdr value. I try to run SDR model for many time for balancing the Soil loss = sediment retention + sediment export.
