中文摘要	A flume system was built to experimentally study unsteady flow and sedimentation. The flume is 20 m long, 29.5 cm wide, and 40 cm high. The system has a water supply facility, water level gauge, a 2-D laser Doppler anemometer (LDA) and a bed-load circulation measurement system. During experiments, hydrographs of the unsteady flow can be generated using a computer, the water level can be measured with 6 pressure transducers installed along the flume, and the vertical velocity distribution can be measured with the LDA. Preliminary experimental data showed that a large amount of experimental data can be obtained by repeatedly generating a series of unsteady hydrographs, including water depth, discharge, velocity and bed load transport. This experimental system provides a foundation for further study on flood characteristics and sediment transport in unsteady open-channel flows.
