Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 2002-02-01 Abstract The severity and location of bank erosion and bed scour changes with the variation of water level. At low flows, the main flow thread tends to follow the concave bank. As the discharge increases, the flow tends to cut across the convex bar, to concentrate against concave bank only downstream the bend apex. This change of flow pattern is important when predicting the magnitude and position of river bed scour during floods. Local scour hole may have a significant effect on the macroscale river morphology (Mossleman et al,2001). Local scour can affect the stability of man-made structures, such as riprap revetments, and lead failure if no counter-measures are against the scour. The migrations of pools may jeopardises the safety of the river dikes; dike collapse events due to this phenomenon are still common in China.
