Abstract

A nested, barotropic numerical tidal model has been applied to the southern New England Bight to include Long Island Sound (LIS), Block Island Sound (BIS), Rhode Island Sound (RIS), Buzzards Bay (BB) and a portion of the southern New England shelf. An explicit finite difference representation of the two-dimensional vertically averaged equations of motion and continuity, employing forward time and centered spatial differences with the bottom friction term being evaluated at both time levels, is applied to the study area to predict tidal circulation dynamics. Horizontal friction and advective terms have been neglected. Tidal height data along the open boundaries is specified from available data. Model predictions of corange and high and low cophase lines agree with available data and show the strongly co-oscillatory behavior of LIS. Tidal current ellipses agree reasonably well with available data showing rectilinear motion in LIS, BIS and BB and rotary motion in RIS. © 1982.
