Abstract

Analyzing river water samples in a laboratory has been the traditional method used to monitor suspended sediment in rivers. In recent years, however, optical backscatter (turbidity), laser diffraction, pressure-difference, acoustic backscatter, and other surrogate techniques have been adopted increasingly according to the circumstances of each measurement point. The author et al. developed a suspended sediment monitoring system based on ultrasonic attenuation spectroscopy. Using the new system, a test was conducted to continuously measure the concentration and particle size distribution of suspended sediment in the Rokkaku River estuary, and it was verified that ultrasonic attenuation spectroscopy is a promising surrogate technique.
