| Description: | Miscellaneous Paper Abstract: An existing comprehensive physical model that correctly reproduced tides, tidal currents, and density currents throughout the entire New York Harbor was used to determine the effects of constructing a current deflection dike at Norton Point, Coney Island, New York. The study included tests in the model to define the effects of the dike on tidal heights, current velocities, surface current patterns, salinities, and the distribution of dye from four sources (Jamaica Bay, Oakwood Beach, Passaic Valley, and Raritan Bay) throughout the New York Harbor complex. The Norton Point current deflection dike studied was an impermeable dike, 3900 ft long, extending from the western tip of Coney Island, south-southeast into Lower New York Bay. Based on results of the model tests, it was shown that the Norton Point dike would have the following effects in the study area: (A.) local current patterns would be changed and a continuous east-west current would be set up along the Coney Island beaches, (B.) tidal heights and tidal phasing as well as the salinity regime would not be affected significantly, (C.) sedimertt buildup behind the dike would be encouraged, (D.) very little flushing of the waters behind the dike would occur in the period while the area is being filled by the littoral drift, and (E.) concentration of pollution from the Passaic Valley Outfall showed a slight net decrease at low-water slack along Coney Island, but a significant net increase at high-water slack.
