I just ran the SDR model for my watershed (Willamette Basin) and got extremely high sediment export values (6 million tonnes per hectare). Any thoughts on where to start looking first as to what could make this value so astronomically high? All other values are also high.
Looking at the soil erodibility and rainfall erosivity the values seem high, even after soil erodibility was converted to the appropriate units.
Soil erodibility on my map range from 8025-370970.
Rainfall erosivity on my map ranges from15831-36819.
The output files are attached as google drive folders. Any insight is appreciated!
Thank you in advance.
