Lake Erie International Jetport Model Feasibility Investigation. Report 17-3 Longshore Wave Energy Analyses


Book Description

The Lake Erie Regional Transportation Authority (LERTA) is conducting a feasibility and site selection study for a major hub airport in the Cleveland Area. One of the possible sites being evaluated is an offshore site in Lake Erie near Cleveland, Ohio. As a part of the feasibility analysis of an offshore site, the U.S. Army Engineer Waterways Experiment Station (WES) is conducting a model feasibility investigation. This report, which is the third of a series, presents results of the longshore wave energy analyses.




Lake Erie International Jetport Model Feasibility Investigation


Book Description

A nontechnical summary of the Waterways Experiment Station's (WES) efforts in a model feasibility investigation of a proposed jetport located in Lake Erie offshore Cleveland, Ohio, is presented in this report. This report is intended to present the basic concepts, procedures and results of the WES model feasibility study without technical details. The following items are some of those presented in a format suitable for the nonscientist: (a) scope and objectives of WES study; (b) factors involved in hydrodynamic modeling; (c) lake characteristics and other information required as input for the models; (d) methods for obtaining unavailable data; (e) numerical and physical model evaluation, selection and preliminary design procedures; (f) information obtained from the models; and (g) current status of WES modeling efforts. Detailed technical data and results from WES study were published by WES in a series of 12 reports. These reports are referenced throughout this report in the appropriate and related sections.

Lake Erie International Jetport Model Feasibility Investigation. Report 17-2 Feasibility Study


Book Description

This report presents the conclusions and recommendations of the U.S. Army Engineer Waterways Experiment Station's study of the feasibility of using physical hydraulic models to estimate the effects of the proposed Lake Erie International Jetport on lake hydrodynamics. This report is the second of a series to be published under the general title 'Lake Erie International Jetport Model Feasibility Investigation.' The physical models considered in the study are mass circulation, wave action, breakwater stability, and longshore littoral transport models. For circulation models, similitude requirements, scales, model verification, and advantages and limitations are considered for (1) a rotating lake model, (2) a rotating model of a section of the lake near Cleveland, and (3) a nonrotating model of a section of lake near Cleveland, all with wind-driven circulation. A fourth circulation model, similar to (3), with slope (gravity) currents is also discussed.

Lake Erie International Jetport Model Feasibility Investigation


Book Description

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.




Lake Erie International Jetport Model Feasibility Investigation


Book Description

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.
