Abstract

The embodiment of the invention provides a tide water change prediction method and device. Arising tide influence coefficient and a falling tide influence coefficient are calculated; and the data ofa tide table is corrected by utilizing the rising tide influence coefficient and the falling tide influence coefficient to obtain local tide water change data, so that the problem that the change of the tide water level does not accord with the data of the tide table due to the influence of different regional terrains or hydrological conditions is solved. A large amount of complex data does not need to be measured, calculation is easy and convenient, and the invention is suitable for rapidly predicting short-term tidal water changes.

Description

technical field [0001] The invention belongs to the field of prediction of tidal changes, in particular to a method and device for predicting tidal changes. Background technique [0002] Tidal phenomenon is a natural phenomenon in coastal areas, which refers to the periodic movement of seawater under the action of tidal forces of celestial bodies (mainly the moon and the sun). The tide phenomenon can be regarded as the superposition of many different periods of the tides. The tide height at any time can be expressed as the height of the mean sea level on the tide height datum. By finding the tidal harmonic constant at a certain point, it can be calculated The high tide and low tide tide time and tide height and the hourly tide height at this point make a daily forecast form - tide table. By querying the tide table, the tide level and tide change trend of the point at any time can be known. [0003] Tide tables are generally made based on the data obtained from a monitoring...
