Комплексные исследования водных экосистем являются неотъемлемой частью рационального природопользования. В этих исследованиях важное место занимает изучение перемещения взвесей, являющихся исходным материалом для образования донных осадков.Основными факторами взвешивания, перераспределения и транспорта донного материала является комбинированное воздействие волн и течений. Частица, вовлеченная внутрь потока, движется в направлении водного потока и, находясь под воздействием переменных по величине и направлению пульсационных скоростей, одновременно непрерывно совершает вертикальные движения (поднимается ‒ опускается).Модель учитывает следующие процессы: адвективный перенос, обусловленный движением водной среды, микротурбулентную диффузию и гравитационное осаждение частиц взвеси, а также изменение геометрии дна, вызванное осаждением частиц взвеси или подъемом частиц донных отложений.В статье представлены результаты исследования корректности начально-краевой задачи, соответствующей построенной модели. Разработан программный пакет для прогнозирования возможных сценариев изменения геометрии дна водоемов на мелководье с использованием высокопроизводительных вычислений.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to the study of the model of transport and sedimentation of suspended solids in the coastal zone. The model takes into account the following processes: advection transport due to the movement of the aqueous medium, microturbulent diffusion and gravitational sedimentation of particles of the suspension, as well as a change in the geometry of the bottom caused by the sedimentation of particles of the suspension or the rise of particles of bottom sediments. The article presents the results of a study of the correctness of the initial-boundary-value problem corresponding to the constructed model. Software package has been developed for predicting possible scenarios for changing the geometry of the bottom of reservoirs in shallow water using high-performance computing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>распределенные вычисления</kwd><kwd>высокопроизводительные вычисления</kwd><kwd>параллельное программирование</kwd><kwd>математическая модель</kwd><kwd>динамика морских наносов</kwd><kwd>рельеф дна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>distributed computing</kwd><kwd>high-performance computing</kwd><kwd>parallel programming</kwd><kwd>mathematical model</kwd><kwd>dynamics of sea sediments</kwd><kwd>bottom relief</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Leontyev, I.O.: Coastal Dynamics: Waves, Moving Streams, Deposits Drifts.
