Abstract
This paper presents a numerical study of the identification of parameters for the tidal fluctuation. Tides can be expressed in the sum of regular trigonometric function which is controlled by the movement of astronomical objects. This trigonometric function is called tidal constituents. In this research, the main four constituents (M2, S2, K1, O1) are treated. The parameters, which are identified, are the amplitude and the phase difference of the four constituents. The parameter identification is carried out based on the optimal control theory. In this research, the sensitivity coefficient method coupled with finite element method is applied. As numerical study, a parameter identification in Tokyo bay is carried out.
