Abstract: In this paper, a quantitative flow visualization technique is used to measure the stern flow field of self-propelled high-speed catamatan. The shortcomings of traditional velocity metre are overcome. On the basis of the measurement of the stern flow field, an analysis on the wake field of fast-moving ship is carried out, and a formula of the corresponding velocity at river bottom is established. Moreover, a local sediment disturbing experiment is done to verify the river-bed variation between scouring and silting of Xiaonan Waterway in Pearl River Delta.
