Abstract

Spur dikes spacing is an important consideration for spur dike of channel layout. It is of important engineering significance to reasonably determine the spacing of the spur dikes. It is found that the maximum scour depth of each spur dike is at the spur dike head. The scour depth of the first dam is the largest, and the scour depth increases with the increase of intensity of water flow. When the river width narrowing rate is 0.25, the spur dike layout should be considered from the perspective of the cover effect of the first spur dike, and the spacing of the spur dikes is between 2l and 3l. The experiment results can effectively reflect the influence of different spur dikes spacing on the scouring patterns and the scour depth of the dam head.
