... for estimation of influence on VLFS incident waves propagating in a layer of water of variable depth. The work of Kyoung et al (2005) include an analysis of the impact seabed topography on the behavior of VLFS modeled as a Kirchhoff plate. Research was conducted to the four variants of the bottom topography...

... by constant depth of basin. We note that the effect of the bottom topography has recently been investigated in the linear problem of the scattering of periodic surface waves by a floating elastic plate (Wang and Meylan, 2002; Sun et al, 2003; and Kyoung et al, 2005) on the assumption that the liquid flow...

... and velocity components obtained by the wave simulation are utilized. This approach is herein referred to as Hybrid-CPM. An example calculation is made for two floating bodies, in which one is a FSRU and the other is a LNGC. These are supposed to be located in specific bottom topography and moored by constant...

... region from wave attack, investigation into reflection of waves due to various bottom topographies is very important. In this study, wave reflection due to various shapes of trench is calculated by using the eigenfunction expansion method (EFEM). This method has advantage of obtaining solutions...

... researchers have attempted to find out the mechanism of the formations of rhythmic patterns of bottom topography and near shore current by theoretical and experimental studies and field measurements. However, due to their dramatic variations in time and space, there are still many outstanding issues...

... ABSTRACT Bottom-mounted IPS and ADCP were used to monitor the drafts and drifts of the pack ice passing over the mooring site on the Sea of Okhotsk off Hokkaido. A spectrum of sea ice bottom topography (draft profile) with non-stationary characteristics was estimated by the locally stationary...

... A phase-resolving, coupled-mode model is developed for the wave-current- seabed interaction problem, with application to wave scattering by steady currents over steep three-dimensional bottom topography. The vertical distribution of the wave potential is represented by a series of local vertical...

The problem of interaction of surface water waves with a semi-infinite horizontal floating membrane having step type bottom topography is analyzed in two dimensions in the linearized theory of water waves. Combining the linearized kinematic and dynamic surface conditions on the water surface...

... and wave kinematics (both on the free surface and within the flow) is carried out. As expected, the bottom topography is found to be an important factor controlling wave transformations and inducing three-dimensional effects on the flow. Nevertheless, comparisons of twoand three-dimensional results...

... ABSTRACT The topographical scattering of gravity waves is investigated using a numerical model based on a spectral energy balance equation that accounts for first order wave-bottom Bragg scattering (Ardhuin and Herbers, 2002). This model represents the bottom topography with a spectrum...

... of the sandbank on the ecosystem at the sea. Furthermore, it is thought that the current field is affected due to the bottom topography change. The influence of the current field change on the water environment is also worried about. So, it is important to clarify the influence of the sand mining on the water...
