Abstract

The AA. explore the link between channel-bed texture and river basin concavity in equilibrium catchments using a numerical landscape evolution model. They begin with a brief overview of the numerical model. They then analyse the effects of sediment sorting on drainage basin morphology by comparing simulated networks with homogeneous and heterogeneous sediment sizes. Downstream changes in both local slope and bed texture are discussed based on results from numerical experiments using a heterogeneous sediment mixture. Finally, investigation of the conditions which must hold under equilibrium provides an explanation of the results
