HIGH WATER WARNING METHOD AND SYSTEM THEREOF ACCORDING TO HIGH WATER REFERENCE VALUE BASED ON TIME

摘要

PURPOSE: An alert generation method and a system thereof regarding a new high water level information standard value are provided to reflect tendency in which variation of a tide level in case of an extreme high water level exponentially increases. CONSTITUTION: A high water level alert generation method regarding a high water level information standard value based on a time includes a stage (S110) for preparing water level analysis DB including annual average water level data averaging water levels in a plurality of time points prior to an annual extreme high water level occurrence time point and an annual approximate maximum high water level, a stage (S120) for deriving a relative formula of a water level with respect to a time reaching to the extreme high water level using the annual average water level data, a stage (S130) for deriving a previous time point from the extreme high water level occurrence time point corresponding to the approximate maximum high water level from the formula to the approximate maximum high water level time point, a stage (S140) for deriving a water level value equidistantly dividing a range from the approximate maximum high water level time point to the high water level time point, a stage (S150) for obtaining a measured water level value and a stage (S170) for generating a high water level alert when the measured water level exceeds the alert standard water level. [Reference numerals] (S110) Prepare annual average water level data and approximate maximum water level data; (S120) Derive a water level relative formula; (S130) Derive a time point of an approximate maximum water level; (S140) Derive a water level value at a regular-interval time point of a maximum water level from the derived time point; (S150) Derive the water level value at the regular-interval time point as an alert standard value; (S160) Experimental water level value > Alert standard value; (S170) Generate an alert
