(TU Delft Rivers, Ports, Waterways and Dredging Engineering) Viparelli, Enrica (University of South Carolina) Chavarrias Borras, V. (TU Delft Rivers, Ports, Waterways and Dredging Engineering) Date 2016 Abstract There has been quite some debate on the relative importance of particle abrasion and grain size selective transport regarding the river profile form and the associated grain size trends in a graded alluvial stream. Here we present new theoretical equations for the graded alluvial river profile that account for the effects of particle abrasion and grain size selective transport in the absence of subsidence, uplift, and sea level change. Under graded conditions we find that abrasion results in a mild profile concavity and downstream fining, whereas under aggradational conditions grain size selective transport can lead to large spatial changes in channel slope and bed surface mean grain size.
