TL;DR: In this article, the coupled dynamic response of a Submerged Floating Tunnel (SFT) and mooring lines under regular waves is solved by using two independent numerical simulation methods, OrcaFlex and CHARM3D, in time domain.
Abstract: In the present study, the coupled dynamic response of a Submerged Floating Tunnel (SFT) and mooring lines under regular waves is solved by using two independent numerical simulation methods, OrcaFlex and CHARM3D, in time domain. Variations of Buoyancy to Weight Ratio (BWR), wave
steepness/period, and water/submergence depth are considered as design and environmental parameters in
the study. Two different mooring-line configurations, vertical and inclined, are studied to find an optimum
design in terms of limiting tunnel motions and minimizing mooring-line tension. The numerical results are
successfully validated by direct comparison against published experimental data. The results show that
tunnel motions and tether tensions grow with wave height and period and decrease with submergence depth.
The inclined mooring system is more effective in restricting tunnel motions compared to the vertical
mooring system. Overall, the present study demonstrates the feasibility of this type of structure as an alternative to traditional bridges or under-seabed tunnels.

TL;DR: In this article, the authors investigated the near future impact of a warmer climate on the global ocean wave climate towards the mid-21st century (2031-2060) through a 4-member ensemble of wave climate projections: single-model (wave model WAM), single-forcing (EC-Earth) and single-scenario (RCP8.5).

TL;DR: In this article, an eddy viscosity model for wave and current is proposed in order to close the equations of wave motion or of current motion in a combined flow, respectively, and equations of mud transport are derived based on the visco-elastic properties of mud.

TL;DR: In this article, a number of meteorological situations are studied using the operational models at the European Centre for Medium-Range Weather Forecasts, and a series of short-term forecast experiments is made for four different resolutions of the meteorological model.
Abstract: A number of meteorological situations are studied using the operational models at the European Centre for Medium-Range Weather Forecasts, and a series of short-term forecast experiments is made for four different resolutions of the meteorological model. A comparison with the measurements and between the corresponding results allows an evaluation of the relative benefits of increased resolution. The focus is on the surface wind speeds and on the wave heights.
Good quality results are found over the oceans, especially in areas with strong spatial gradients. Consistent with the already good quality of the present operational results, the improvements with increased resolution are small, but significant. In enclosed basins, as in the case of the Mediterranean Sea, it is found that both the surface wind speed and wave height are strongly underestimated. The improvements with increased resolution are greater than over the oceans, but still not sufficient to give agreement with measured data. Copyright © 2003 Royal Meteorological Society

TL;DR: In this paper, a floating breakwater integrated with oscillating water column (OWC) wave energy converters is presented, where the energy extraction and motion characteristics of the installed devices are explored across parameters including device configurations, breakwater width, power take-off damping, wave height and motion constraints.
