This Special Issue focuses on simulations of hydrodynamic and sediment transport phenomena that take place in coastal regions, rivers, and in transition zones such as river mouths and lagoons.

The simulation of these phenomena allows us to evaluate hydrodynamic forces and the evolutive processes that affect the abovementioned regions and.

currents, water levels), sediment transport and changing morphology is the main tool to gain insight in the long-term processes, to predict future changes and to set up an integrated sand policy in the coastal zone. A simplified model for the area of Blankenberge is set up both in XBeach and in Delft3D.

In this paper, the entrainment and movement of coarse particles on the bed of an open channel is numerically investigated. Rather than model the sediment transport using a concentration concept, this study treats the sediment as individual particles and investigates the interaction between turbulent coherent structures and particle entrainment.

The protective works of the harbour consist of two curved rubble mound breakwaters. The mathematical modelling is made by the littoral drift and coastline evolution model LITPACK and by the area model system MIKE21 for the wave field, the wave driven currents, the resulting sediment transport and the morphological bed evolution.

The numerical modeling system is semi-three-dimensional; sigma coordinated; and containing wave, flow, sediment transport, and morphological change sub-modules. Horizontal mixing of bed sediment due to wave action proportional to the number of grid points across the surf zone [18] is also included in the model as a smoothing process of morphology.
