Abstract

Often river bed form modelling is done with an equilibrium bed load transport formula like that of Meyer-Peter & Müller (1948). However, a physically more correct way would be to model it with separate models for the sediment pick-up and deposition processes as described by Nakagawa & Tsujimoto (1980). Besides the physics of the sediment transport itself, using such a method allows for the modelling of higher-order processes as well like spatial lag in bed load transport.
As shown by Shimizu et al. (2009) applying the aforementioned pick-up and deposition model in a dune evolution model, makes is possible to model dunes well. Specifically it made it possible to determine a transition to upper stage plane beds, as well as capturing hysteresis well.
In this paper we will explore the effect of using different kinds of bed load models in a relatively simple dune evolution model. The Nakagawa & Tsujimoto (1980) bed load model, will be implemented in the dune evolution model of Paarlberg et al. (2009). Results of this model version will be compared with the original version (using the Meyer-Peter & Müller formula) and a later version that directly models spatial lag with a relaxation equation.
