The problem of incipient motion of a loose boundary has been extensively investigated in open channel flow by many investigators. Also substantial amount of information is available on limit deposit velocities or incipient deposition conditions in full pipe flow. The paper forming an extension of the authors' earlier studies presented at the Second International Conference on the Hydraulic Transport of Solids in Pipes, 1972, deals with a study of incipient motion in open channels of rectangular and circular cross-section with fixed smooth beds. It has been attempted to analyze and summarize the similarities and differences between sediment motion in open channels with smooth fixed boundaries and with moveable bed and in full pipe flow with particular reference to incipient motion. The experimental results are also discussed in the light of turbulence measurements carried out by the authors.
