深度基准面的略最低低潮面比值传递法研究
Research on Indian Spring Low Water Ratio Datum Computation Method
摘要
Abstract
Spatial distribution of the ratio of Indian Spring Low Water (ISLW) to Lowest Normal Low Water (LNLW),calculated by tide model,is analyzed.The contour shows complex distribution over China Seas.So the applicability of the ISLW ratio method can't be judged by the distance or the type of tide.Based on three pairs of tidal stations,the accuracy of transferring in different synchronous time length is assessed.When the synchronous time length is longer than 7 days,the variations of the error are in 15cm.Systematic error may be exist according to the applicability of the ISLW ratio method.Contour of the ratio ISLW to LNLW is given as the reference for the applicability judgment.关键词
