Abstract

Abstract

To improve the tidal prediction accuracy, the error correction of a regional tidal model is carried out using a local model approach based on chaos theory where sufficient tidal measurement data were available. As the examples, for one month (December-2007), the local model correction can remove as much as 74.7% of root mean square error (RMSE) at Chongwu measurement station and 60.5% at Xiamen Station for the prediction horizon T=2 h, and remove around 50% RMSE at above two stations for the prediction horizon T=24 h.
