A straight shoreline is disturbed by a coastal structure which is semi-circular shaped in plan view. If the waves approach the shore normally as indicated by the black arrow in the figure below, roughly sketch the wave crest curves around the structure. Assume that the shoreline bathymetry is uniform in the alongshore direction.
