Current and density structure in shelf waters due to fresh water discharge - A numerical study
Abstract
The current and density structure of the Middle Atlantic Shelf water due to a line source of fresh water input from the shore is analyzed using a two-dimensional numerical model incorporating the full nonlinear advection terms in the momentum equations. The full time-dependent diffusion and Navier-Stokes equations for a constant Coriolis parameter are solved by a finite-difference scheme. The central difference in space and the forward difference in time are used, except for the nonlinear terms, for which the three-point noncentral difference method is adopted. A stretched coordinate is used in the horizontal direction, and the governing equations are then appropriately scaled. A physical interpretation of the results is presented.
