Abstract/Summary

The DESC model seeks to explore the interactions that exist between Earth systems at a range of spatio-temporal scales by coupling current landscape evolution modelling technologies to a host of new geo-processing modules. DESC currently uses the well established CAESAR model (Coulthard and Van De Wiel, 2006) as its kernel; a two-dimensional cellular automaton landscape evolution model which has a modular design and great versatility in the range of simulated spatio-temporal scales. Initial research focused on the loose coupling of CAESAR to the groundwater flow model ZOOMQ3D, investigating the role of groundwater on sediment transport at the catchment scale. The Eden Valley (Cumbria, UK) was selected as a test bed for the coupled model and results suggest that although the volume of sediment transport through the catchment is not altered, the distribution of sediment erosion and deposition in the simulation is perturbed by the interplay of baseflow conditions and storm intensity and frequency.
