Sediment modeling is generally conducted using physically-based erosion models.
From these, the most-cited erosion models were identified.
In general, slurry erosion models obtained experimentally were found to have better agreement with literature models when compared to air-jet erosion models.
Thus soil erodibility estimated with many interrill erosion models was actually sediment transportability.
Sediment transport capacity (Tc) is a key parameter for all process-based erosion models.
Accurate estimation of sediment concentration is essential to establish physically-based erosion models.
Soil erosion models need detailed runoff and infiltration data as input.
Application of soil erosion models requires accurate estimation of model parameters under different environmental conditions.
To assess water erosion of the study area, the erosion models, USLE and spectral indices, were applied.
Several brittle erosion models are available for air-jet and slurry jet erosion in literature.
Lumped interrill erosion models, developed from short slopes, are likely to overestimate erosion rates.
