| Abstract: | A simple expansion technique is developed for predicting the response of a horizontally sheared oceanic coastal flow over uniform coastal topography to variations in that bottom topography. The technique is illustrated by application to supercritical and subcritical flows. The response of the supercritical flow is local, while that of the subcritical flow extends downstream to be eventually attenuated by frictional damping. However, the response of both flow types is weak unless the flow is nearly critical. |
