Abstract: The evolution of the shoal patches of Shizikou,Wujiang River and its waterway regulation is studied. Form the viewpoint of relations between the sediment transport and the river channel evolution,the obstructing navigation mechanism is elucidated. The principles of minimum energy dissipation rate observed by the evolutional processes of channel morphology are applied. The properties of energy distribution in space of the complex shoals in curved river channel regulating is explored. The effective concrete regulating measures are explored for the complex shoals in curved mountain river channel on the basis of physical experiments. The properties of complex shoals of curved river regulation are summarized finally,and the results are valuable to regulation study of the mountainous rivers.

Key words: Shizikou, waterway regulation, energy distribution
