| Abstract: | A method of determining tidal heights based on tidal model improved by residual water levels is proposed. A tidal model has been constructed based on regular grids, and the model quality is improved by a method of interpolating residual water levels. By using strategies of grid searching, depths grid is orientated efficiently, and water levels is created. Then method is applied in correction and prediction of water levels. The experimental results show that the proposed method could be used to correct and predict water levels respectively. It is more accurate than existing methods both in correction and prediction of water levels. |
