The wind-driven circulation for thermally stratified lake conditions in a 16-mile by 16-mile nearshore region offshore Cleveland, Ohio, is studied for existing conditions and conditions as modified by a proposed jetport island. A steady-state 12 mph west wind, which produced maximum jetport effects in a previous WES study of the steady-state wind-driven circulation for well-mixed lake conditions in the nearshore region offshore Cleveland, Ohio, was chosen as the wind field for the model study. In a previous contracted study by WES, a 12 mph south wind, which represents the modal wind speed and most frequently occurring wind direction for the months of July, August, and September, was used in studying the proposed jetport effects on wind-driven circulation for summer lake conditions. For the 12 mph west wind field, results for the horizontal velocity and temperature regimes with and without a jetport are presented. Included in the results are plots of horizontal velocity vectors and isotherm contours with and without a jetport and contours of differences in hori zontal velocity and temperature regimes in the nearshore region due to jetport. Based on the results of this study and a previous WES contracted studyl using a 12 mph south windfield, the effects of a proposed jetport island on wind-driven circulation for thermally stratified lake conditions are that (A.) major island influences of engineering interest are contained within 3 to 5 miles of the island, (B.) velocity changes of 0.25 ft/sec extend to the shore in the immediate vicinity of Cleveland, Ohio, while temperature changes of 0.5°F extend within 1 mile of the shoreline, and (C.) maximum changes in velocity and temperature (1.5 fps and 15°F) regimes occur within 2 miles of the island in strong upwelling and downwelling regions along the perimeter of the island.
