Numerical simulation of tide in the Bohai Sea based on the finite-volume coastal ocean numerical model (FVCOM)
基于FVCOM 的渤海潮波数值模拟

Based on the finite-volume coastal ocean numerical model (FVCOM), we simulated K1, O1, M2 and S2 tidal constituents in the Bohai Sea by new coastline and topography. It can fit well with the shoreline in the Yellow River Estuary by using irregular triangle meshes for the model. Compared with the observation data obtained from 19 stations, we found that the result is reasonable to reflect the tidal transmission. For K1, the mean absolute difference of the amplitude is 2.39 cm, the mean absolute difference of the phase-lag is 4.36°. For O1, they are 1.40 cm and 4.29°. For M2, they are 3.55 cm and 5.69°. For S2, they are 1.72 cm and 8.86° respectively.
