Модель описывает движение водного потока, термодинамику формирования и таяния льда, учитывает силу Кориолиса, горизонтальную и вертикальную турбулентность водной среды, сложную геометрию береговой линии и дна, трение о дно и ветровые течения, испарение, скорость ветра и плотность атмосферы, отклонение значения поля давления от гидростатического приближения. В работе проведено исследование влияния пространственного распределения температуры, солености, ионного состава и гидростатического давления на процессы формирования ледового покрова. В качестве объекта моделирования был выбран водоём (озеро) – Каспийское море. В качестве входных данных используются изменения распределений температуры и солености, измеренные по электропроводности воды с учетом ионного состава вод Каспийского моря за многолетний период. Моделирование движения водного потока позволят реагировать на техногенные угрозы в ускоренном режиме времени. Представленные в работе модели гидродинамики, могут быть адаптированы для других водоемов при использовании соответствующих геоинформационных систем.</p></abstract><trans-abstract xml:lang="en"><p>This article is devoted to the development and research of a mathematical model of water fluid dynamics with variable depth. This model describes the water flow movement, the thermodynamics of ice formation and melting, considers the Coriolis force, horizontal and vertical turbulence of the water environment, the complex geometry of the coastline and bottom, friction on the bottom and wind currents, evaporation, wind speed, and atmospheric density, and the deviation of the pressure field value from the hydrostatic approximation. The article describes the influence of the spatial distribution of temperature, salinity, ionic composition, and hydrostatic pressure on the processes of ice cover formation. The Caspian Sea-was chosen as the object of the simulation. The changes in the temperature and salinity distributions measured by the electrical conductivity of the water, considering the ionic composition of the Caspian Sea waters over a long-term period, are used as input data. Modeling the movement of water flow will allow you to respond to man-made threats in an accelerated time mode. The models of hydrodynamics presented in this paper can be adapted for other reservoirs using the appropriate geoinformation systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Каспийское море</kwd><kwd>гидродинамические процессы</kwd><kwd>льдообразование</kwd><kwd>ионный состав</kwd><kwd>математическое моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Caspian Sea</kwd><kwd>mathematical modeling</kwd><kwd>water flow velocity field</kwd><kwd>ice formation</kwd><kwd>ionic composition</kwd><kwd>temperature</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 19-31-51017.</funding-statement><funding-statement xml:lang="en">The reported study was funded by RFBR according to the research project № 19-31-51017.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Matishov, G., Dashkevich, L. and Kulygin, V.
