We present an analysis related to the evaluation of Morison and transverse force coefficients in case a submerged square barrier subject action solitary waves. To this purpose, two-dimensional experimental research was undertaken wave flume University Calabria, which rigid provided by discrete battery pressure sensors determine horizontal vertical hydrodynamic forces. A total set 18 laboratory ...

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...

This paper presents potential upgrades to the Palm Jumeirah Island’s outer revetment extend its design life for 50 years, considering sea level rise (SLR) associated with climate change. The proposes several upgrade options ensure that hydraulic stability and wave overtopping discharges of comply recommended criteria based on industry guidelines. performance existing revetment, in terms dischar...

Wave energy and storm surges threaten coastal ecology and nearshore infrastructures. Although coastal structures are conventionally constructed to dampen the wave energy, they introduce tremendous damage to the ecology of the coast. To minimize environmental impact, ecofriendly coastal protection schemes should be introduced. In this paper, we discuss an example of an innovative mangrove rehabi...

Compared to the hydrostatic hydrodynamic model, the non-hydrostatic hydrodynamic model can accurately simulate flows that feature vertical accelerations. The model’s low computational efficiency severely restricts its wider application. This paper proposes a non-hydrostatic hydrodynamic model based on a multithreading parallel computing method. The horizontal momentum equation is obtained by in...

Shoreline stability is an important issue along much of the Mediterranean’s Coasts. European project MEDDOOC INTERREG BEACHMED-e focused on the strategic management of beach protection for the sustainable development of the Mediterranean coastal zone. In the framework of this project, a video system has been installed in Valras (Gulf of Lions / France) to monitor coastal evolutions and recent p...

An angular spectrum model for predicting the transformation of Stokes waves on a mildly varying topography is developed, including refraction, diffraction, shoaling and nonlinear wave interactions. The equations governing the water-wave motion are perturbed using the method of multiple scales and Stokes expansions for the velocity potential and free-surface displacement. The first-order solutio...

In this study, the Bragg resonance of water waves scattered by multiple permeable thin barriers over a series periodic breakwaters was solved employing eigenfunction matching method (EMM). The geometrical configuration divided into shelves separated steps, on which were implemented. solution approximated using eigenfunctions with unknown coefficients that considered as amplitudes for each shelf...

Niigata West Coast faces the Sea of Japan and Sado Island is located approximately 45 km to west from there (Fig.1). This coast has suffered severe erosion since early 1950s. Hiyoriyamahama beach where a part highly erosive beach. For protection erosion, combined shore system with jetty, submerged wide breakwater nourishment have been constructed at There, strong winds NW WNW blow in winter sea...
