Abstract:

The results of modeling the spatial distribution of sediment transport and seabed deformation in the Pechora Sea are presented. The modeling has been performed using the Delft3D-FLOW hydromorphodynamic model, which includes modules for wave calculations (SWAN) and hydrodynamic currents (FLOW), as well as a sediment transport module. The calculations have been conducted for two periods, each lasting two years. Data on the direction of instantaneous and averaged sediment flows have been obtained, and the total volume of transported sediments has been estimated. The study shows that significant vertical seabed deformations occur in the area from Cape Svyatoy Nos to Vaigach Island at depths of up to 30—50 m, with sediment flow directions varying depending on wind direction. The modeling results are compared with existing empirical data on sediment flows.
