... part of the upwards projected water to be transported landwards over the crest. Some research studies have suggested that the effects of onshore winds on large overtopping discharges (so called "green water") are relatively small; on the contrary when the overtopping is below q = 1 l/s per m, it might...

...). The arrival time of wave crest, the wave amplitude and deformation, and the velocity of water particles are analyzed. It turns out that the 3D topography has a significant effect on the wave amplitude and deformation of solitary waves but no obvious influence on the arrival time of wave crest...

... crest has a significant effect on wave attenuation with a weak wave attenuation on the seaward slope. Wave dissipation coefficient is larger than transmission coefficient, which is bigger than reflection coefficient on account of vegetation. Besides, wave attenuation ratio nonlinearly increases...

The overtopping discharge was evaluated in 2D and 3D tests collecting water passing over the structure crest, neglecting...

... ABSTRACT The stability of rock on low crest sea dike under construction has been investigated in 2D physical model tests. The tests and analysis are addressed on the front slope with a berm as well as the crest. Moreover, the stability of the rock at the toe is analyzed. The influence...

... parameters, the choice of H s (significant wave height) and T p (peak spectral period) needs to take into account the possible occurrence of wave breaking. For a given exceedance probability, while a sea-state with the largest H s will porbably generate the highest crest, it will not necessarily...

... wave transmission. The leading crest and leading trough deform slightly due to shoaling effect when the wave passes on the front slope of the submerged obstacle. As the wave approaches the front slope, the flow in lower layer increases because of the narrow width between the leading trough and front...

..., SWASH. It was found that freak waves are readily formed at the seaward part of the crest of the bar and gradually emerged from an intense wave group. The enhancement of the bound higher harmonics in the shoaling process is the main reason to form such large waves in shallow water. On the crest bar...

... fringing reef profiles with or without reef crest is then numerically investigated. INTRODUCTION Fringing reefs are commonly found along coastlines in the tropical and subtropical regions around the world. A typical fringing reef is characterized by a sloping (or composite) reef face with an abrupt...

... ABSTRACT Long waves approaching a cliff over a variable bathymetry are investigated. The waves experience extreme runup amplifications at the cliff, and wave breaking may occur. Kinematic, steepness, and wave height to depth metrics are applied locally to the crests. The generally accepted...

Sand ripples have usually a symmetric shape with respect to the crest due to the oscillatory nature of the boundary layer flow induced by the propagation of waves. A typical 3-D rippled bed is shown in Fig. 1...
