Ecological Systems and Devices Annotation << Back Modelling of internal waves in the coastal zone of the Barents Sea Talipova T.G. Kurkina O.E. Terletskaya E.V. Kurkin A.A. Rouvinskaya E.A. Necessity of study of the internal waves of large amplitude in the Barents Sea related to their possible catastrophic effects on offshore platforms, powerful transport sediments and bottom erosion, which invariably affects on the overall environmental situation. In this paper, numerical simulation of the generation and propagation of internal waves in the Barents Sea in the framework of the two-dimensional version of the full nonlinear Euler equations for a plane layer of ideal stratified fluid taking into account the Earth’s rotation is made. The transformation of the barotropic tide at depth break is mechanism of internal wave generation. The height of the tidal wave in the coastal area is estimated at about 1,5…2 m, and the average speeds of the tidal wave in the Kola Peninsula are amounted to 20…25 cm/s. This tide leads to generation of internal waves with heights up to 15 m. Calculations are performed for three incisions near the southern part of the Kola Peninsula near the point of Vostochnaya Litsa differing on hydrology and depth. Only density stratification of the ocean is considered. Statistical estimates of the possible amplitudes of internal waves in this region are made.
