According to 1991's statistics, about 184 events of tide bore occurred at the Lunqian Tidal Sta-tion.the statistics show that a relationship exists between the occurrence number of the tide bores and the changesof the channel topography and the discharge from upstream.The heights of the tide bores at the Lunqian TidalStation usually range from 1.2 m to 2.2m,directly proportional to the rising tidal range. The method of propaga-tion time and the method of tide lag can be used for forecasting the occurrence-time of tide bore.As for the tidalheight forecasting,it is possible in practice to forecast the height on the following day according to the currentbeight,or forecast the tidal height at the station on upstream based on the height at the station on downstream.
