Computation of Tides, Currents and Dispersal of Pollutants in the New York Bight from Block Island to Atlantic City with Large Grid Size, Single and Two- Layer Hydrodynamical-Numerical Models, Part 4
Abstract
The application of a large grid HN model to the New York Bight is to large extent a problem of treating two long open boundaries. The input at these open boundaries serves also for tuning of the results inside the computational area. A few earlier current measurements by two lightships in the Bight as reported by Haight (1942) have been used for verification. The tidal currents predominate in the New York Bight proper, with a superimposed slow net flow toward the south. This net flow can be simulated in the models and tuned with the prescription of a proper slope to the two open boundaries. The diffusion computations over a short period of time in the large grid models do not give fully satisfactory results with the diffusion model used at present in the HN models, instead, the transport of the centers of release points have been computed and presented. Furthermore, the net transport through various sections in the area has also been computed. The single-layer model is applicable for the winter season when the area is fully mixed from surface to the bottom.
