Bedload Transport in Storm Sewers: Stream Traction in Pipe Channels

摘要

The purpose of the thesis is to analyze the flow conditions that characterize the stream traction in pipe channels and their relationship to sediment transport rate, flow resistance and bedform dimensions based on previous and present experiments made by the author and on relationships suggested by other authors. Further, the assumptions of a logarithmic velocity distribution, the side wall elimination procedure, and the critical shear stress as obtained from Shields' diagram, all commonly used (but seldom verified) in this type of experimental study, were all tested to corroborate the validity of the computations.
