Measurements of the fine space-time structure of short gravity-capillary waves in the presence of turbulence, as well as Ku-band scattering at grazing and moderate incidence from mechanically-generated waves in a wave channel are presented. This study was stimulated by the need to investigate the influence of nonlinear features of the scattering surface, which contribute to scattering at grazin...

The results of the analysis data on observation short-period internal waves northeastern shelf Black Sea in June 2018 are presented. study area is distinguished by a narrow with sharp drop depths, bottom slope 23°. measurements were carried out from stationary marine platform Institute Ecology Academy Sciences Abkhazian Republic, where depth site reaches 13 m. An anchored station was installed,...

Abstract Coastal wave conditions are highly influenced by bathymetry variations and coastlines. The Norwegian fjords present large gradients of changes irregular coastline geometries that make the understanding near-coast a challenging task. proposed floating bridges for permanent fjord-crossings along E39 coastal highway require reliable efficient numerical simulations domain at fjords. In thi...

In this paper we establish the existence and analyticity of periodic solutions of a classical free-boundary model of the evolution of three-dimensional, capillary–gravity waves on the surface of an ideal fluid. The result is achieved through the application of bifurcation theory to a boundary perturbation formulation of the problem, and it yields analyticity jointly with respect to the perturba...

Experiments on extremely steep deterministic waves generated in a large wave tank by focusing of a broadbanded wave train serve as a motivation for the theoretical analysis of the conditions leading to wave breaking. Particular attention is given to the crest of the steepest wave where both the horizontal velocity and the vertical acceleration attain their maxima. Analysis is carried out up to ...
