Abstract

Abstract: The finite volume coastal ocean model (FVCOM) has been applied to establish a high-resolution numerical model of tide in Haizhou Bay. The time series of astronomical tidal values at each grid point are extracted. The water level correction model is used to extract the water level correction data from the five tide station data in this area, and the water level of the grid site is corrected. The water level time series of the grid is obtained with high precision, then the modified water level value is interpolated. The instantaneous sea surface height is obtained at a certain time. The results show that the water level accuracy is improved by about 10 cm based on the numerical simulation of water level correction and the sea surface height model has been improved obviously.

Key words: FVCOM, tidal numerical simulation, residual water level
