Wave overtopping on the breakwaters is an important issue in breakwaters’ design. Most of the previous studies focused on experimental researches and numerical modeling of irregular wave overtopping particularly on porous breakwaters has not been studied. In the present study, the verification between experimental studies and numerical modeling of irregular waves overtopping on the porous...
This research paper presents an incompressible smoothed particle hydrodynamics (ISPH) technique to investigate a regular wave overtopping on the coastal structure of different types. The SPH method is a mesh-free particle modeling approach that can efficiently treat the large deformation of free surface. The incompressible SPH approach employs a true hydrodynamic formulation to solve the fluid ...
in this paper the telemac-3d model has been hired to simulate and study the high waves’ interaction with coastal structures. therefore a special arrangement of telemac-3d has been prepared in this study to simulate wave generation, coastal processes, wave set-up and overtopping over coastal structures. experimental data has been used to verify this arrangement of the model. thereafter, the mode...
Wave overtopping at breakwaters is one of their essential hydraulic characteristics when determining the design crest level. This study concentrates on developing a new practical formula on predicting wave overtopping, by implementing two different statistical models, Multiple Linear Regression model (MLR) and Generalized Linear Regression model (GLM). The models consider dependency of overtopp...
An overtopping model specifically suited for Wave Dragon is needed in order to improve the reliability of its performance estimates. The model shall be comprehensive of all relevant physical processes that affect overtopping and flexible to adapt to any local conditions and device configuration. An experimental investigation is carried out to update an existing formulation suited for 2D draft-l...
A new and symmetrical single layer armour unit, the crablock, has been designed in the UAE. One breakwater was reconstructed with crablock, but very limited testing had been performed. Just to become more acquainted with this new unit, precompetitive research at a university has been performed, which is the subject of this paper. Being a new armour unit, the placement was investigated first. Th...
A numerical wave flume based on the particle finite element method PFEM is applied to simulate wave overtopping for impermeable maritime structures. An assessment of the performance and robustness of the numerical wave flume is carried out for two different cases comparing numerical results with experimental data. In the first case, a well-defined benchmark test of a simple low-crested structur...
in this paper, a two-dimensional reynolds averaged navier-stokes (rans) model is developed to simulate the shoaling, breaking and overtopping of a solitary wave over a vertical breakwater. turbulence intensity is described by using a k turbulence closure model and the free surface configuration is tracked by volume of fluid (vof) technique. to validate the numerical model the simulation result...
Breakwaters have changed a lot during their design history. Overtopping is an important parameter that its evaluation and reduction has always been noticed. In this study, the wave overtopping of composite berm breakwater as a new conceptual structure has been investigated numerical modeling was performed using FLOW-3D software. Then, based on a laboratory model conducted by Losada et al, cali...
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...
