“…Two principal types of two-dimensional (2D) numerical models have been used, i.e. two-dimensional horizontal (2DH) [1][2][3][4] and two-dimensional vertical (2DV) models [4][5][6][7][8]. 2DH models, based on the depth-integrated equations, could simulate the horizontal distributions of tidal ows, but vertical variations are parameterized or treated in terms of analytic functions.…”

SUMMARYAn estuarine two-dimensional vertical ÿnite-element model of tidal ow has been established by laterally integrating Navier-Stokes equation. To this end, a moving grid ÿnite-element method has been used. An arbitrarily shaped quadrilateral element has been selected. This model has been validated by using ÿeld data from two monitoring stations at the North Passage of the Changjiang Estuary. Using this numerical model, two types of modelled results were obtained: (1) vertical distributions of tidal current velocities at the North Passage of the Changjiang Estuary; (2) longitudinal distributions of tidal current velocities at maximum ood tide, at high slack water, at maximum ebb tide and at low slack water tide at the North Passage of the Changjiang Estuary. The conclusion is that the model provides a reasonable agreement with observed data.
