Abstract: The incipient motion of cohesive sediment in flows of large depth was studied both experimentally and theoretically. An experiment consisting of 75 runs with three kinds of fine sediment show that both the flow depth H and the dry unit weight of the deposited sediment have important influences on incipient motion. Authors developed a relationship between the cohesive force and these two factors, and established an incipient motion formula for fine sediment particles. Experimental data collected from various resources agree with this theoretical result.
