| Numerical computation of diurnal tide and tidal current in Luoyuan Bay |
|
|
| Abstract: |
| Using the split steps finite element method, the varied-boundary two-dimensional numerical model of diurnal tide and tidal current in the Luoyuan Bay is constructed. The tally of computation and observation is in a good agreement. The tide and the tidal current in Luoyuan Bay can be known from the numerica model calculation. Diurnal tide and tidal current at different times and the eulerian residual current are calculated, also the cotidal line, the iso-amplitude curves and the distribution of tidal current ellipses are given in this paper. |
