Research on water level reckoning of virtual tide station in outer port waters
摘要
Abstract
During the surveying of the port and fairway charts,for the purpose of tidal level control,in addition to using long-term tide stations,other short-term/temporary tide stations need to be established.How to deeply utilize the historical water level data accumulated by standing short-term tide stations to effectively reduce the workload of tidal observation has become a practical issue that needs to be solved in hydrographic surveying and charting practice.The paper is based on the historical synchronous measured water level data of long-term and standing short-term tide stations in ports,and adopts tidal difference correction and residual water level transfer technology to achieve a reliable-precision method for restoring the water level of virtual tide stations in outer port waters.Moreover,the paper summarizes the applicable conditions of tidal difference correction for short-term stations,and the difference correction algorithm and the calculation steps of virtual station water levels extraction.The verification and accuracy assessment verifies that the calculation accuracy of the virtual tide station's restoring water levels by the mothed of astronomical tide level plus transfered residual water levels of adjacent tide station meet the requirements of relevant technical specifications.关键词
