• Spatial Distribution Analysis of Suspended Sediment by Applying CT Scanning-Type Turbidimeter and Non-Linear Inverse Analysis

抄録

The new type turbidimeter, CT scanning-type turbidimeter is proposed in this paper. It is an optical system that can measure instantaneous turbidity distributions in the target cross section. Its target measurement area is 480 mm x 480 mm. The hardware of this system has no moving part, and measure the instantaneous turbidity distributions every 0.1 s without disturbing flow field. To evaluate turbidity distributions from observed raw data, the extended Bayesian method are employed in this system. The method is non-linearized and accuracy of the evaluation is improved in this system. This system is applied to the measurement of the suspended sediment of sand in a surf zone in laboratory experiments, and suitable distributions and behavior of the sand are observed with the system.
