My fluid physics is a bit rusty, but a flow of water parallel to the surface would actually decrease the pressure (higher velocity, lower pressure). A flow perpendicular to the surface increases the pressure, at least at one point, by d*vē/2 (d: density, v: velocity). Since the increase in pressure due to immersion is d*g*h (g: gravity acceleration, h: depth). For a pressure equivalent to 1m immersion, you need a velocity v=sqrt(2*g)=4.4 m/s
