The possibility of temporal variations in the earth tidal amplitudes associated with earthquakes has first been suggested by nishimura . 西村首先提出与地震有关的固体潮振幅随时间变化的可能性。
2.
This method is better than the traditional method that relates the divergence of sediment transport rate to the deposition rate . the output of the tidal modelling reaches the required precision according to a comparison between the calculated tidal amplitudes / phases and the observed ones at 42 coastal tide gauge stations 潮汐潮流的模拟计算结果与沿岸42个潮汐测站的实测值结果对比达到了精度的要求，同时，计算得到的各分潮同潮图与实测结果相符。
