This research studies the distribution of wave amplitude, and phase and velocity field of tidal waves including the effects of the Earth’s rotation. This research aims are two folds. One is to find a selection rule of the parameters in the chosen numerical method. The other one is the take advantage of the chores numerical method to determine tidal velocity field, after amplitude and phase of tidal waves are found.
In this research, the modified finite point collocation method (MFPM) is applied to establish a numerical model of tide flow hased on an extended mild-slope equation（1991）, describing the phenomenon of combined reflection, diffraction and refraction of tide flow.
Compare numerical model with analytic solution, it is concluded that a numerical model employed by MFPM can solve the problem of combined wave refraction and diffraction. Besides, this research has developed an rule for feller systematical selection of the parameter in the present numerical method, in order to achieve a accurate result.
