摘要
主要介绍在钱塘江涌潮连续观测中,首次采用新型OBS-3A浊度计进行该水域的悬沙浓度测量,并对悬浮泥沙的变化规律与涌潮的关系进行了试验分析与研究。通过采集盐官站待测水域的泥沙进行室内标定,将标定曲线分为三段的数理方法处理,分别拟合得到相应曲线方程,然后将涌潮观测中OBS采集到的浊度数据,经标定曲线转化为泥沙含量。通过含沙量变化过程线的分析,得到了反映涌潮特征与含沙量等要素的相关关系的结论。实测结果对钱塘江涌潮期间泥沙沉降规律的研究提供了有益的帮助。
Observation of suspended sediment concentration was carried out using an OBS-3A in tidal bore in Qiantang River for the first time.The relationship between the change of suspended sediment and tidal bore is researched.Sediments of Yanguan station were collected for laboratory calibration.The calibration curve was divided into three sections to be processed.The OBS counts were then converted to sediment concentration.Process curve about sediment concentration reflected the characteristics of tidal bore,which is a useful inspiration to study the law of sedimentation of tidal bore in Qiantang River.
