Wave Energy in Brittany (France)—Resource Assessment and WEC Performances

Refined numerical wave energy resource assessments are required to reduce uncertainties in the evaluation of available power and energy production. However, to restrict the computational cost, a great part of wave hindcast simulations cover a limited time range (below ten years) or rely on coarse spatial resolutions while routinely ignoring tide...

Evaluation of new Eurocode ‘prEN1991-1-8’ on wave and current actions: Case study IJmuiden - Does the new Eurocode improve the current design practice of breakwaters and other coastal structures?

The Eurocodes are design codes, widely accepted throughout Europe, that provide guidelines on how to deal with loads, resistance, and uncertainty. For most type of structures, loads and materials, the Eurocode has been well developed. However, for the loads on coastal structures, caused by wave, water level and current actions, no such Eurocode...

Observations of Bedform Migration and Bedload Sediment Transport in Combined Wave-Current Flows

Bedload transport is an important mechanism for sediment flux in the nearshore. Yet few studies examine the relationship between bedform evolution and net sediment transport. Our work contributes concurrent observations of bedform mobility and bedload transport in response to wave dominant, current dominant, and combined wave-current flows in...

Numerical simulations of surf zone wave dynamics using Smoothed Particle Hydrodynamics

In this study we investigated the capabilities of the mesh-free, Lagrangian particle method (Smoothed Particle Hydrodynamics, SPH) to simulate the detailed hydrodynamic processes generated by both spilling and plunging breaking waves within the surf zone. The weakly-compressible SPH code DualSPHysics was applied to simulate wave breaking over...

Efficient non-hydrostatic modelling of 3D wave-induced currents using a subgrid approach

Wave-induced currents are an ubiquitous feature in coastal waters that can spread material over the surf zone and the inner shelf. These currents are typically under resolved in non-hydrostatic wave-flow models due to computational constraints. Specifically, the low vertical resolutions adequate to describe the wave dynamics – and required to...

Generating and absorbing boundary conditions for combined wave-current simulations

The CFD simulation tool ComFLOW is extended to investigate the characteristics of wave motions in the presence of steady uniform currents. Initially, the inflow boundary is the superposition of waves and current. Effect of the latter on the former is resolved by solving Navier-Stokes equations within the domain as a next step. A Generating and...

Evaluation and development of wave-current interaction in SWAN: Activity 6.4 of SBW project Waddenzee

Numerical simulation of wave-current driven sand transport: Theoretical background of the beta-release of the POINT-SAND model

Secondary circulation of the flow due to waves and current: Laser-Doppler flow measurements for waves following or opposing a current

Nearshore circulation

Shelf circulation is driven primarily by wind- and tide-induced forces. It is laterally only weakly constrained so that the geostrophic (Coriolis) acceleration is manifest in the response. Nearshore circulation on the other hand is dominated by wave-induced forces associated with shallow-water. wave breaking and is confined to a relatively...

Hydrodynamic forces on a near-bed offshore pipeline with spoiler, during the selfburying process

To prevent offshore submarine pipelines from damage by fishing gear, the formation of dangerous free-spans and excessive wave and current forces, it is a requirement that these pipelines are completely buried under the seabed. Usually pipelines are buried artificially by means of ploughing, digging or jetting in order to meet the requirements of...

Analyse brandingsstroommetingen nabij Joossesweg (Westkapelle)

In de periode maart tot april 1985 heeft de Adviesdienst Vlissingen enige brandingsstroommetingen uitgevoerd voor de kust van Walcheren ter hoogte van Joossesweg (nabij Westkapelle). Het doel van het meetonderzoek is het verkrijgen van meer inzicht in de veranderingen die optreden op een gesuppleerd strand ten gevolge van stroom en golven. Met...
