Abstract
In this paper, the mathematical modeling of the hydro-, litho- and morphodynamic processes occurring in the coastal zone of the Ob Gulf, where the construction of the port terminal “Utrenny” of the Sabetta port of liquefied natural gas is planned to build, is considered. Local and integrated sediment flows are calculated, which makes it possible to estimate the deformations of the seabed and the shoreline under various storm situations, and to determine the deposition conditions of the approach navigation channel and the adjacent water area to the port. The coasts within the construction site are mainly accumulative, composed of fine sandy material. The coastal slope within the wave action zone has an average slope of 0.01 and is characterized by the presence of a system of underwater shafts. Statistical characteristics of the wind waves in the Kara Sea and the Ob Gulf, were calculated by the wind fields for the period 1987-2016 by the SWAN spectral wave model, version 41.10AB. Also, the calculation of wave fields in the water area of the Terminal of liquefied natural gas and stable gas condensate “Utrenny”, was performed in the spectral mode of the wave model ARTEMIS. In the paper we have solved two important tasks, the first one was the modeling of waves and lithodynamics and was carried out for 3 Terminal layout options, given by situational plans. The second task was to forecast the waves characteristics and lithodynamics for each of the 3 years of construction of the final layout of the protective structures and facilities of the terminal “Utrenny”.
