Abstract

Bathymetric information is essential for navigational purpose. The depth in navigational charts has to be referred to a vertical datum with the intention of ships can navigate safely. Tide plays important rule in a depth reduction in order to provide bathymetric information. Tidal characteristics are unique for any different places. The tidal phase and amplitude propagation may cause difficulties in predicting water levels. The research utilized Tidal Constituent and Residual Interpolation methods to estimate the tide propagation and to achieve a smooth tidal zoning. Tidal constituents at each of observation point are calculated using the least squares method and interpolated based on Laplace formula. The tidal zoning model that has been developed then was compared to the Finite Element Solution 2014 Global Tide Model. The results show that the correlation coefficient between those models is 0.78. Based on the research, the tidal zoning model can be used to improve the global tide model.
