OBS 500光学后向散射浊度仪在马口水文站泥沙监测应用分析

采用相关关系分析方法,通过马口水文站传统含沙量分析与OBS 500光学后向散射浊度仪泥沙监测应用比测分析,建立水体浊度与泥沙浓度的相关关系,进行浊度与泥沙浓度的转化,进而实现含沙量在线监测方式。OBS泥沙监测方法简单、处理速度快、可实现实时连续监测,对于在复杂珠江三角洲网河区域实现泥沙在线监测具有现实的推广意义。

Application Analysis of Sediment Monitoring of OBS 500 in Makou Hydrological Station

Hydrological observations in the content of water and sediment tests is a very important element. Traditional analysis of sediment is tedious, time-consuming and inefficient, and not able to do continuous monitoring. Optical back scatter sensor (the OBS) is real-time, rapid monitoring of suspended substances characteristics. Correlation analysis, traditional adoption of Makou hydrological station sediment analysis and OBS 500 application comparison analysis of sediment monitoring are used to establish correlation between turbidity and sediment concentration of water, turbidity and sediment concentration of conversion, and online monitoring of sediment. OBS sediment monitoring method is simple, fast, real-time continuous monitoring; online monitoring sediment in complex river network of the Pearl River Delta region has a realistic significance.
