Description :
Here, the AA. use the saltation-abrasion model to generate a large suite of predicted steady-state river profiles, in order to evaluate the relative influence of each of the key variables (discharge, grain size, sediment supply, rock uplift rate and rock strength) in controlling profile concavity and profile relief. They conclude by considering some of the possible covariation of these key variables, in particular the likely dependence of grain size on both rock uplift rate and rock strength.
