Low value of sedi_export as compared to usle_total
I am using the SDR model in an area where the dominated LULCs are forest, fallow and crop land. I am getting very low sedi_export value (about 0.3 Million ton ) as compared to usle_total (about 9 Million ton) . I have considered C values for forest, fallow and crop land as 0.001, 0.18 and 0.2 respectively and have considered P values as 0.5 for urban area and 1 for rest LULCs. I have checked the SDR value and found maximum value as 0.21 and mean value as 0.04 which is very low. I think, the value of sediment_export is low due to low value of SDR if I am right. Any suggestion of how to increase the sedi_export (i.e. increase SDR if I am right) will be highly appreciated.
Thanks in advance.
