Представлены результаты лабораторных экспериментов по трансформации нелинейных внутренних волн первой и второй мод над склоном. На основе математической модели трехслойной мелкой воды с учетом негидростатичности распределения давления проведены численные расчеты эволюции волн большой амплитуды и дано их сравнение с экспериментальными данными. Построено точное решение, представляющее несимметричную уединенную волну второй моды, и дано экспериментальное подтверждение существования несимметричных солитонообразных волн, распространяющихся по границе раздела между однородными слоями различной плотности.</p></abstract><trans-abstract xml:lang="en"><p>Wave motions of stratified fluid over uneven bottom are considered. The results of the laboratory experiments on the transformation of nonlinear internal waves of the first and second mode on the slope are presented. The numerical calculations of the evolution of large-amplitude internal waves using a mathematical model of the three-layer shallow water with the non-hydrostatic pressure distribution are compared with the experimental data. The exact solution, which represents an asymmetric solitary wave of the second mode, is constructed. The experimental confirmation of the existence of asymmetric solitary waves propagating along the interface between the homogeneous layers of different densities is presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стратифицированные течения</kwd><kwd>внутренние волны</kwd><kwd>несимметричные солитоны</kwd><kwd>трехслойная мелкая вода</kwd><kwd>разрушение волн</kwd><kwd>шельфовая зона</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы благодарны рецензентам за конструктивные замечания.
