Soil erosion modelling at European scale by using high resolution input layers [PDF]

, 2015
Soil erosion by water is one of the most widespread forms of soil degradation. Since soil erosion is difficult to measure at large scales, soil erosion models are a crucial estimation tool at regional, national and European levels. The high heterogeneity
