VERIFICATION OF THE RESULTS OF THE SWAN MODEL FOR THE WATER AREA NEAR PORT AKTAU

The development of shipping and offshore drilling of new fields has led to an increase in the need for high-quality data on wave characteristics in the Caspian Sea. The purpose of the research is to verify the accuracy of the SWAN model in predicting wave characteristics in the water area near Port Aktau, in the Caspian Sea. The study also aims to provide high-quality data on wave processes at sea, which is important for the development of shipping and offshore drilling activities in the region. This paper analyzes the characteristics of wind and waves at the coastal station Aktau. Calculations of wave processes at sea were made using wave and wind data and numerical simulations using the SWAN model. The influence of the wind on the direction of the wave height is determined. The results show that the change in wave parameters depends on the speed and direction of the wind. An analysis showed that the waves directed to the southeast have the greatest frequency, and the wave height could reach 3.5 meters. In this paper, the modeling of wave processes, altimetry satellites, and their relationship with the SWAN wave model are investigated.
