Abstract: A method of distinguishing between the signals from the liquid-seed particles and sediment particles, while using LDV in sediment-laden flows, is described. The validity of the method was tested in measurements made in a flume. It was also found that off-axis forward-scatter detection was more promising than backward-scatter detection for the measurement of particle velocities due to better signal-to-noise ratio. However, since signals from dust were also recorded in forward-scatter detection, an auxiliary system to identify signals from sediment particles was required.
