Abstract

Abstract

In order to find a simple and continuous method to measure a suspended sediment content in a high turbidity region, a conductivity sensor was used to examine the conductivity in different sediment content seawater. Sediments from the Huanghe River Delta were used. The previous test has proven that good linear relationships exist between the suspended sediment content and the conductivity. On that basis, the scope of study was expanded. And the influencing factors of such relationships were also investigated. The results show that salinity, temperature and particle size have some influence on the conductivity, among which salinity is the most influencing factor and the influence of particle size is not important. In this way, the general relationship between the suspended sediment content and electrical conductivity was achieved through a large number of test data in a large scale of salinity and temperature. They provide reliable data support for realizing the monitoring system in situ.
