Wave-resolving Voronoi model of the Rouse number for sediment entrainment

Abstract. To integrate wave and sediment transport modeling, a computationally extensive wave-resolving Voronoi-mesh-based simulation has been developed to improve upon heretofore separate sediment and spectral wave modeling. Sediment entrainment by wave motion and fine scales of the dynamic Rouse number distribution across the seabed were brought into focus. The entirely parallelized wave-resolving hydrodynamic model is demonstrated for nearshore beach waters adjacent to artificial islands in Doha Bay. The nested model was validated with tidal time series for three locations and two seasons.
