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.en1812-079220253877896Copernicus Publicationshttps://creativecommons.org/licenses/by/4.0/Natural Sciences and Mathematics::530: PhysicsTechnology::627: Hydraulic EngineeringJournal Articlehttps://doi.org/10.15480/882.1596810.5194/os-21-877-202510.15480/882.15968Journal Article
