Abstract : The wind-driven circulation and dispersion of contaminants in a near-shore region of Lake Erie have been Studied by means of numerical models. The first problem studied was that of the thickness of the coastal boundary layer in a large lake. In this study, the non-linear acceleration and Coriolis force terms were included in the equations of motion. Next, a major study of the steadystate and time-dependent currents in the near-shore Cleveland area of Lake Erie, under present conditions and as modified by large man-made structures or islands, e.g., a jetport in the lake, was made. The effects of (1) a jetport island approximately 6 miles offshore of Cleveland, and (2) a land-fill extension of this island to shore, were examined in detail. The island was found not to affect the flow appreciably while the extension to the shore modified the flow significantly. With some modification, the numerical models developed in this report can be applied to study the near-shore regions of other large lakes and the ocean.
