WAVE OVERTOPPING AND SPLASH GENERATED AT FLARED SHAPE SEAWALL UNDER STORM

Computational modelling of combined storm surge and wave overtopping of embankments

In this paper we investigate the process of embankment wave overtopping combinedwith overflow due to extreme surge levels that are above the embankment crest. AReynolds Averaged Navier-Stokes (RANS-VOF) model is employed to simulate thehydrodynamics. To investigate the success of the model at reproducing thehydrodynamic processes, the model is compared with experimental laborato...

Wave Overtopping over Sea Dikes and Impact Forces on Storm Walls

Experimental investigation of wave parameters effect on damage of the berm reshaped seawall under irregular wave attack

This paper presents an experimental study the influence of wave parameter on the damage of reshaping seawall, model tests have been performed in several water level conditions. The experiments of physical modeling of this research have been done in the flume of the Soil Conservation and Watershed Management Research Institute (SCWMRI). The waves applied to the structure model are irregular and ...

Boussinesq Modelling of Solitary Wave Propagation, Breaking, Runup and Overtopping

A one-dimensional hybrid numerical model is presented of a shallow-water flume with an incorporated piston paddle. The hybrid model is based on the improved Boussinesq equations by Madsen and Sørensen (1992) and the nonlinear shallow water equations. It is suitable for breaking and non-breaking waves and requires only two adjustable parameters: a friction coefficient and a wave breaking paramet...

Erosional equivalences of levees: Steady and intermittent wave overtopping

Present criteria for acceptable grass covered levee overtopping are based on average overtopping values but do not include the effect of overtopping duration. This paper applies experimental steady state results for acceptable overtopping to the case of intermittent wave overtopping. Laboratory results consisting of velocities and durations for acceptable land side levee erosion due to steady f...
