Norton Point Dike Study, Coney Island, New York. Hydraulic Model Investigation.
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 throughout the New York Harbor complex. Based on results of the model tests, it was shown that the Norton Point dike would have the following effects in the study area: local current patterns would be changed and a continuous east-west current would be set up along the Coney Island beaches, tidal heights and tidal phasing as well as the salinity regime would not be affected significantly, sediment buildup behind the dike would occur in the period while the area is being filled by the littoral drift, and 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.
