Abstract

The AA. present a newly developed dynamic and spatially-explicit EROsion and sediment DEPosition model (ERODEP), which simulates soil erosion by stream power principles, sediment deposition based on texture-specific settling velocity classes, and sediment re-entrainment to move previously deposited particles back into runoff flow. ERODEP runs on a daily basis and was linked with the Land Use Change Impact Assessment model (LUCIA) building on its hydrological and vegetation growth routines. The combined modelling framework was employed for a period of 4 years using field datasets of a small case study watershed, in Ban Tat, Hoa Binh province. ERODEP-LUCIA simulated reasonably well soil erosion and sediment deposition patterns following the annual variations in land use and rainfall regimes. Results highlighted the potential of ERODEP-LUCIA as an integrated biophysical assessment tool for mountainous ecosystems with moderate data availability
