Abstract

Water level forecasts with a high river water discharge depend on accurate predictions of the evolution of river dunes. For flood earlywarning systems complexity in sub models is a drawback as it leads to (too) large computation times. Therefore the aim of this study is to develop a relatively simple dune evolution model that works well in the dune regime, and which has the potential to predict the upperstage plane bed as well. To reach this goal we will study the influence of using certain bed load transport formulations on the resulting dune morphologies. For this we will investigate whether alternative bed load transport models within the computationally cheap model of Paarlberg et al. (2009) lead to good results.
