considering particle size is the way if yes.
should it be just as a, for example, some particle size which we bring in the code for that area or it is as a factor which involves in soil type data? if not what is the solution for that.
WEPP (Water Erosion Prediction Project) may be helpful In considering erosion, sediment movement and delivery.
To enrich the organic matter in soil, it is better to use legumes byproduct plant material with non-legminous one ,so that due to close L:N ratio decomposition would be faster. It may increase the magnitude of soil microbial biomass ,an active fraction of soil organic matter. This may help to reduce the turnover time of recalcitrant passive fraction of soil organic matter
It can be done by developing a two dimensional physically based model of soil erosion and sediment transport coupled to models of hydrological and overland flow process. The Hairsine-Rose formulation of erosion and deposition processes can be used to account for size -selective sediment transport and differentiate bed material into original and deposited layers. the formulation is integrated within the framework of the hydrologic and hydrodynamic model tRIBS-OFM, triangulated, irregular based, real time integrated Basin simulator overland flow model.
