Numerical Calculation of the Tidal Currents in Yashima Bay

Abstract

A mathematical method was developed to predict the tidal motion in all study site. The basis of computation were the vertically integrated Navier-Stokes equations and continuity equation in and Eulerian system. The considered forces were inertia, coriolis, pressure gradient and friction. The effect of viscosity of sea water was introduced. The wind stress would be neglected. The solutions of tidal current computation were obtained on the basis of the scheme of explicit method by Ueno (1967). Since the solution of this model was solved by numerical method, so the effects of stability and convergence had to be considered. The use of the computational procedure was illustrated with results of tidal computations of the Yashima Bay, Japan
