Abstract ontraction of the flow leads to the flow modification; at the heads of the guide banks take place streamline concentration, sharp drop in water level, local increase in velocity, vortex structure, increased turbulence, local scour and as well general scour up and down of the bridge. The differential equation for the bed sediment movement under clear-water conditions is used, and a method for computing the scour development during multiple floods is presented.The method is confirmed by experimental data.
