Reduction of wave overtopping and force impact at harbor quays due to very oblique waves

Physical model experiments were conducted in a wave tank at Flanders Hydraulics Research, Antwerp, Belgium, to characterize the wave overtopping and impact force on vertical quay walls and sloping sea dike (1:2.5) under very oblique wave attack (angle between 45° and 80°). This study was triggered by the scarce scientific literature on the...

Characterization of overtopping waves on sea dikes with gentle and shallow foreshores

Due to ongoing climate change, overtopping risk is increasing. In order to have effective countermeasures, it is useful to understand overtopping processes in details. In this study overtopping flow on a dike with gentle and shallow foreshores are investigated using a non-hydrostatic wave-flow model, SWASH (an acronym of Simulating WAves till...

Two-Dimensional Wave Overtopping Calculation over a Dike in Shallow Foreshore by SWASH

In this paper, a numerical wave-flow model SWASH, based on non-linear shallow water equation with non- hydrostatic pressure, is applied to the estimation of wave overtopping over a dike in shallow foreshores. First sensitivity analysis is conducted to see the influence of wave generation, grid size, time window and bottom friction by one...

A numerical study on the effect of beach nourishment on wave overtopping in shallow foreshores

In this paper, the effect of beach nourishment on wave overtopping in shallow foreshores is investigated with the nonhydrostatic wave-flow model SWASH. Firstly, the applicability of SWASH to model wave overtopping is tested by comparing results with a physical model setup with different storm wall heights on top of an impermeable sea dike. The...

Hydrodynamic load on the building caused by overtopping waves

Wide crested dike can reduce the kinetic energy of the overtopping wave and make the overtopping wave to flow back to the seaside. If a coastal town were built on or near a dike, the overtopping wave running on the dike crest generates the force which can affect the buildings located in its path. However, quantifying the hydrodynamic load on the...
