The Bosphorus Strait, connecting the Black Sea with the Sea of Marmara, is one of the narrowest straits. At the same time, the strait is a place of intensive international shipping, which requires a comprehensive study of the water dynamics in this area, in particular, the possible greatest wave heights that can penetrate into the strait from the Black and Marmara Seas. In this paper, we studied the propagation of long waves in the Bosphorus Strait using the ADCIRC numerical hydrodynamic model. Spatial distributions of sea level during the propagation of long waves in the Bosphorus Strait were analyzed for different scenarios of their generation. Three cases of wave generation were considered: propagation of a single wave in the Bosphorus Strait from the Black and Marmara seas; propagation of a tsunami in the strait; and sea level disturbance caused by bottom movement inside the strait. It has been established that when single long waves penetrate the strait, the height along the strait axis does not exceed the initial wave height, while level fluctuations near the coast could increase by more than 1.5 times compared to the height of the initial disturbance. The maximum level increases in the Bosphorus Strait when tsunami waves penetrate from the Black Sea could reach over 1.6 m. When a tsunami from the Sea of Marmara spread in the strait, the level increase was about 2.7 m. The generation of disturbance as a result of bottom movement inside the strait did not lead to significant amplification of sea level fluctuations.
