137 the hydraulically smooth surface of a well-streamlined plate with end washers 2 m long and 0.5 m wide. The plate was fixed to the bottom of the hydrodynamic channel at a height of 0.1 m from its bottom. The flow depth in the hydrodynamic channel was 0.4 m. Thus, the flow depth above the top of the seamount model was 0.1 m. The flow velocity (U) in the hydrodynamic channel varied from 0.05 m/s to 0.20 m/s, and the Froude numbers (Fr=U 2 /gH) and Reynolds numbers (Re=UL H/2 /  ), which were calculated from the height of the seamount model (H=0.20 m) or its width (L H/2 =0.15 m) at the half-height (H/2) level and the flow velocity, where g is the gravitational constant and  is the kinematic viscosity coefficient of water. The range of changes in the Reynolds and Froude coefficients in the conducted researches was as follows: Re=(7.5-30)*10 3 and Fr=(0.001-0.02). According to the developed program and methodology of experimental research, visual researches were performed using video cameras and instrumental measurements of velocity and pressure fields in the vicinity and on the streamlined surface of the rough model of the Atlantis II seamount. Visualization was implemented using colored dyes, which were fed through miniature thin-walled tubes. Using digital cameras and video cameras, visualized patterns of dye trajectories were recorded and transmitted to computer equipment. Results and discussion. The results of visual reseaerches of the interaction of the simulated Gulf Stream flow with the rough model of the Atlantis II seamount for a flow velocity of 0.1 m/s are presented in Fig. 2. The red dye was applied along the center of the mountain ridge at a level of 0.01 m below the mountain peak, or z=-0.05H and at a distance of 0.01 m from the mountain, x=-0.05H, the green dye was applied to the edge of the mountain ridge at a distance of 0.055 m from the center of the mountain closer to the gorge between the mountains (edge of the ridge y=0.28H), the black dye was applied from the opposite edge of the mountain at a distance y=-0.28H.
