Implications of the Saltation—Abrasion Bedrock Incision Model for Steady-State River Longitudinal Profile Relief and Concavity.

The article examines the implications of the saltation-abrasion model for steady-state river longitudinal profile relief and concavity. It investigates the controls on river longitudinal profile concavity and relief using an experimentally calibrated model. It focuses on the case of topographic steady state, in which the rate of vertical rock uplift is equal to the rate of channel incision. The study also carried out a comprehensive sensitivity analysis and explores a variety of key potential linkages among the variables that together control river longitudinal profile form.
