Description :
In this paper, the AA. carry out a more detailed evaluation of the MAHLERAN model (Model for Assessing Hillslope-Landscape Erosion, Runoff And Nutrients) using monitored erosion events on plots of different size. Although the model produces the correct ranking of the magnitude of erosion events, it performs less well in reproducing the absolute values and particle-size distribution of the eroded sediment. The implications of these results are evaluated in terms of process representation and explicit scaling characteristics when compared with existing models.
