ultrasound imaging measurement for suspended sediment concentration and its vertical distribut

What is it about?

In this paper, a novel approach based on B-scan ultrasound imaging is presented to measure suspended sediment concentration (SSC) and its vertical distribution. The relationship between ultrasonic imaging signals and SSCs has been described by specially designed experiments on both natural and plastic sand. It is confirmed that these parameter values increase with the sand added in the case of low SSC and can be used to measure the unknown SSC.

Why is it important?

Characterised by direct observation, high sensitivity and real-time processing performance, this method has proved suitable for the measurement of SSC below 5.0‰ by volume or approx. 10 kg m−3 by weight, especially for the measurement of vertical sedimentary distribution in the movable-bed model experiment.
