Abstract
New data on scouring around vertical and wing wall abutments embedded in clay/sand-mixed beds are reported and the mechanism of the scouring process is described. In total, 87 experimental runs on vertical wall abutments and 30 experimental runs on 45° wing wall abutments in cohesive beds were conducted. The effect of clay content, water content, bed shear strength and pier Froude number on maximum equilibrium scour depth, scouring process, and time variation of scour were investigated. Further, equations for estimation non-dimensional maximum scour depth for vertical wall abutments embedded in clay–sand mixtures are proposed as functions of pier Froude number, clay content (C), water content (Wc), and bed shear strength for 0.35 ⩽ C ⩽ 1; 0.19 ⩽ Wc ⩽ 0.44. In addition, shape correction factor for 45° wing wall abutments in cohesive sediment beds is evaluated.
