Methods for production of tidal stream atlases using the Digital Tidal Stream Atlas S/W

摘要

The present invention relates to a tidal current chart production method for each lunar (solar) time based on numerical tidal current chart that is tidal current/tide prediction software using tidal current/tide differential harmonic constant materials developed in Korea hydrographic and oceanographic agency, and more specifically, to a method for producing harmonic constant materials for input with respect to a time, from tidal current/tide differential harmonic constant materials for inputting a numerical tidal current chart in order to estimate a tidal current field for each lunar (solar) time with respect to a horizontal space by including an intertidal zone with respect to a mean spring tidal period, a mean middle tidal period, and a mean neap tidal period. Also, the present invention relates to a tidal current field estimation method by using a corrected conventional tidal current/tide harmonic prediction algorithm for producing a regular tidal current field with respect to the mean spring tidal period, the mean middle tidal period, and the mean neap tidal period regardless of an estimation time, and more specifically, to a method capable of implementing a tidal current field of an intertidal zone flooded/exposed particularly during a spring tidal period in the sea in which the intertidal zone is well developed and a tidal range is large. By using the tidal current field estimation method, it is possible to produce not only a tidal current chart with respect to a time passing through a lunar area standard meridian that is a standard for issuing a tidal current chart of Korea hydrographic and oceanographic agency, but also a tidal current chart with respect to a time of high water of a neighboring standard tide station that is used abroad like England, or the like. Also, it is possible to provide an estimation method with respect to the fastest flood current field and the fastest ebb current field of the sea for which the tidal current chart is issued.
