The crest level of coastal structures such as dikes and breakwaters is often based on estimates the amount wave overtopping. One important parameters affecting overtopping angle incident waves since oblique can significantly reduce compared to perpendicular attack. Based 3D physical model tests dikes, rubble mound vertical caisson breakwaters, influence attack has been evaluated. A new expressi...

Abstract: Flood waves resulting from dam break and spillway gate malfunction may have dramatic impacts. Two related cases are the overtopping of a dam by flood waves and a sudden water release down a stepped cascade. In each instance, some energy dissipation takes place and classical dam break theory are inappropriate. Both cases were investigated in large-size facilities and in a prototype. Ne...

This paper presents a study of run-up/overtopping over smooth impermeable dike with promenade using 2D and 3D mesh-based mesh-free numerical models results from physical modelling for strong energetic incident waves. These waves induce plunging wave breaking complex water/air mixture turbulent flow before overtopped the dike, challenging configuration models. The analysis is structured in two p...

Overtopping flow velocity (OFV) and overtopping layer thickness (OTL) are essential parameters in breakwater design. Several empirical equations to predict these available many works of literature, but most the were derived based on impermeable structures such as sea dikes. In this study, we experimented with waves over a composite tetrapod armor units. experiments, wave was generated from regu...
