Abstract

A comprehensive process-based numerical model of catchment hydrology and alluvial channel dynamics is applied to the evolution of the river Maas during the Last Glacial-Interglacial Transition. Palaeo-climatological reconstructions based on a number of climatic and environmental proxies are combined with atmospheric circulation model predictions to yield continuous time series for temperature, precipitation and vegetation cover for the period of 14-9 C-14 kyr BP. These climatic data are used as input for the numerical model. Predictions are made for discharge statistics, hillslope erosion potential, river channel sediment transport, channel pattern and incision potential. These predictions are compared with reconstructed fluvial dynamics of the Maas during this time period. We find that the major fluvial morphodynamical events can be explained by our model as a result of climate change induced affects. However, relatively high precipitation amounts during GS-1 must be applied in order to correctly predict floodplain wide incision during this period. We further show by means of a number of sensitivity analyses that the uncertainty in the adopted climate reconstructions do not have a large impact on modelled morphodynamics.
