Verification of modeling of dynamic processes in the port structures area

Abstract

For problems involving the interaction of structures with sediments, physical models cannot be used for quantification because of the non-modellable nature of sediment dynamics. Mathematical modeling of sediment dynamics is used. The basis for verifying modeling results for such problems is in situ studies of coastal dynamics over a multi-year period, which are often not available. It is therefore possible to use the analysis of space images for a multi-year period together with a mathematical description of the dynamics of the coast under study. The subject of this paper is the coast of the Gelendjik Bay, Black Sea. An assessment of the coastline dynamics in the conditions of 5 extreme wave storms of 30-year period is made using mathematical modeling. To verify the results, the analysis of space images of the coastal zone for the period 2003-2022 is applied. The effectiveness of the proposed approach for predicting the intensity of sediment accumulation and erosion is shown and the mathematical model used is verified.
