How do modeling choices and erosion zone locations impact the representation of connectivity and the dynamics of suspended sediments in a multi-source soil erosion model?

Magdalena Uber, Guillaume Nord, Cédric Legout, and Luis Cea

Data sets

Modeled contributions of sediment sources to total suspended sediment flux in two mesoscale catchments. Uber, M., Nord, G., Legout, C., Cea, L. https://doi.org/10.17178/EROSION_MODEL.2020

Short summary

Understanding soil erosion and suspended sediment transport is an important issue in terms of soil and water resources management. This study analyzes the impact of choices made during numerical model setup on the modeled suspended sediment dynamics at the outlet of two mesoscale watersheds. While the modeled liquid and solid discharges were found to be sensitive to these choices, the actual location of sediment sources in each catchment was the most important feature.
