An Experimental Study of the Local Scour around Bridge Main Pier across a River

In the paper,a simulation experiment of generalized normal movable bed was conducted to investigate the local scour cross the river bridge pier.The results of study show that the depth and scope of the scour hole have a close relationship with the bed surface geological conditions,water depth,velocity,width and shape of the pier.In addition,the relationship between local scour and flow,and the maximum scour depth have been concluded,and the protective measures of local scour have been proposed as well.
