We implemented 4 additional process-based soil erosion models, so the model can be used as a soil erosion model ensemble. The additional models included DHSVM, HSPF, INCA and SHETRAN. These soil erosion models are similar to the MMF model, but have some important differences regarding the simulation of detachment by runoff and immediate deposition. Some models require more physical properties, like rill dimensions, or include a sediment storage in the deposition routine. The soil erosion model ensemble was applied in a case study in the Mula catchment (SE Spain), where we showed how differences in model concepts affect uncertainty in a climate change impact assessment.
