Abstract

Abstract

In order to find a simple,continuous method to measure suspended sediment content in a high turbidity region,experiments were conducted to examine relationship between suspended sediment contentand electrical conductivity.Sediments from the Huanghe River Delta and a conductivity sensor were used. The influencing factors of influencing this relationship were also investigated.The results show that good linear relationships exist between suspended sediment contentand electrical conductivity;salinity and grain-size have some influence on the electrical conductivity,of which salinity is the most influencing facto rand grain-size has little influence.The linear relationships suggest that it is feasible to measure suspended sediment content in situ using the electrical conductivity sensor.
