... the former two phases is a common feature. It may occur due to air-cushioning, whereby the liquid surface deforms by a small amount due to high stagnation pressure, entrapping a thin air layer (Verhagen 1967, Peters, Gordillo & van der Meer 2013, Jain et al. 2021). Alternatively it can occur when either...

... The design of toe berm with two layers of stone to support the sloped rubble mound structure is typically done with the formulation by Van der Meer et al (1995). In this study, a wide scour protection layer to enhance the toe berm stability with reduced toe armour sizes has been adopted. The two-dimensional...

... in term of function, aesthetics, and cost is often one that allows overtopping under extreme conditions. On the other hand, in the design of the crest elevation of a seawall, usually a tolerable wave overtopping rate is applied (Owen,1980; Goda,1985; van der Meer,1994). In general speaking, prediction...

... ABSTRACT The wave overtopping rate over dike is influence major by the crest height, the surface roughness as well as the slope angle of the dike. Owen (1980) and van der Meer (1998) proposed several predict equations to estimate wave overtopping rate. Those equations are regressed from...

... function originally expected to the breakwater is not lost after the deformation. Moreover in low-crested breakwater the size of individual armour stone on the surface of the front slope and crest can be smaller because wave energy can pass over the crest (Van der Meer and Pilarczyk (1990)). In order...
