135 with a flat top nearly 1,580 m long [4]. The steep relief of seamounts and coastal slopes generates turbulence, wake flows, and vortex structures through baroclinic or barotropic instabilities, which are crucial for the ecology of the ocean space and global climatic processes and phenomena. Thus, seamounts are sites of vorticity generation through the interaction of ocean flows and topography, and since seamounts are sources of internal waves, they contribute to vertical mixing between the density layers of ocean water. The key mechanism for the generation of submesoscale vortex structures and wake flows is the separation of the boundary layer from the streamlined surface of the seamount and the formation of vorticity layers and internal waves in the seamount wake, which propagate both vertically and transversely relative to the flow direction. The interaction of the Gulf Stream with near-bottom inhomogeneities of complex bathymetry leads to significant temporal and spatial variability of sound velocity and its propagation in the vicinity of such inhomogeneities, especially large- scale ones, where the effects of interference and dissipation of acoustic fields are observed [2, 5, 6]. The formation and generation of nonlinear, inhomogeneous, and nonstationary acoustic fields over and near seamounts, ridges, and slopes causes significant interference for hydroacoustic systems, antennas, and receivers, which significantly complicates the movement and location of underwater and surface vehicles and vehicles, especially small-scale drones, gliders, ekranoplanes, and autonomous vehicles, which are also significantly affected by hydrodynamic submesoscale inhomogeneities in the form of vortices, jets, and wave flows due to their oscillation and drift [7, 8]. The purpose of the work is to determine the features of the interaction of the flow with the model of the Atlantis II seamount in laboratory conditions. Materials and methods. In accordance with the program and methodology of scientific research, visual and instrumental researches of the interaction of the flow with objects of rough bottom topography were conducted. In the hydrodynamic channel, the interaction of
