# Soil erosion model calibration

Each soil erosion model can be calibrated in more or less the same way, except for the MUSLE model, which is typically applied without model calibration. All other models include several parameters that can be used for model calibration. The soil erodibility is often used for calibration, to adjust the soil erosion values for land use classes that do not have ground cover, such as frequently ploughed orchards. Model parameters related to ground cover and more specific vegetation characteristics (e.g. stem density, stem diameter and root cohesion) are subsequently used to calibrate the soil erosion for specific land use types. We refer to Eekhout & de Vente (2020) and Eekhout et al. (2021), in which all 6 soil erosion were applied and give some specific recommendations for model calibration.
