Abstract: Water levels along Qiantang estuary are mainly controlled by tidal level at Ganpu station, the lower boundary of Qiantang Estuary. Since the large tide range, severe deformation of tide wave, changeful underwater topography etc, if only use harmonic analysis to forecasting high tidal level at Ganpu station, the precision is hard to satisfy requirement. The method introduced in this paper has two steps, namely linear self-tuning model is used based on harmonic analysis results. This method can be better to catch the effect of short period factors, and the forecast precision is raised greatly.
