Accuracy Assessment of Numerical Morphological Models Based on Reduced Saint-Venant Equations

In this paper we investigate under which conditions numerical morphological models can be simplified to speed up simulations, and still provide accurate predictions of riverbed dynamics. We show that popular simplified models based on the quasi-steady approach are highly accurate for Froude numbers up to 0.7, probably even for long river reaches with large flood wave damping. We provide diagrams (see example below) for assessing the accuracy of simplified models (quasi-steady and diffusive wave) for various combinations of Froude number, sediment transport and dimensions of riverbed waves.
