Abstract

Experiments were conducted to investigate the bed form and flow resistance of the light-weight sediment in an open channel flow. Three different synthetic materials with specific gravity 1.055, 1.46 and with uniform sizes D50 1.25mm, 1.05mm, 1.40mm were used. Some conclusions were obtained from experimental results and the data of other reliable references. The conclusions indicate that the grain resistance is greatly affected by D50, and the bed form resistance is the function of the downstream slope and height of dune As well as natural sand, Y is not only the function of Y', but also affected by the relative roughness Rb/D50 and the size of used sediment.
