Few, if any, civil engineering structures exposed to wind or water flows are free of strong boundary-layer effects induced within the flow by the nearness of the ground. The velocity or shear gradient then acting on the structure provides marked three-dimensional flow patterns in the wake, changing the pressure distributions from those to be expected in two-dimensional conditions. The study of this effect forms the topic of this paper, and is carried out for various shear gradients but always with the same boundary and structure geometry. Local vortex shedding correlations are demonstrated, but structural oscillation is excluded.
