Abstract

This study compares 3 landscape evolution models and their ability to correctly simulate measured 2 500 year landscape evolution in 2 small catchments in the Belgian loess belt : WATEM LT and LAPSUS as examples of detachment-limited models and WATEM LTT as an example of transport-limited model. All 3 models are DEM based. Tests demonstrate that a transport-limited approach cannot be used to model long-term landscape evolution in the Belgian loess belt. The difference in performance between transport-limited and detachment-limited models is clear only when the models are evaluated in a 2D catchment. The lack of such distinction when models were applied in a 1D transect highlights the importance of evaluating landscape evolution models in a 2D setting so that effects of flow convergence/divergence can be accounted for
