A set of model equations for water wave propagation is derived by piecewise integration of the primitive equations of motion through N arbitrary layers. Within each layer, an independent velocity profile is determined. Depth-averaged and ‘‘extended’’ versions of the multi-layer model are presented and compared. With N separate velocity profiles, matched at the interfaces of the layers, the resu...

Turbulence models are critical for depth-averaged flow in at least two ways: (i) as closures momentum equations and (ii) indicators of the spatial variability turbulence intensity field, which is crucial sediment transport bedform evolutions. This paper introduces a novel moment-based k-ε (MDAKE) model that could be considered revised version standard Rastogi–Rodi (SDAKE) can used to estimate t...

Sedimentation is one of the most important problems in harbors that results in considerable economic costs. Harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. In the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...
