LOCAL SCOUR AT BRIDGE PIERS

Local scour at cylindrical bridge piers in both uniform and nonuniform cohesionless sediments was investigated experimentally. The aim of the study was to improve understanding of local scour around bridge piers with sediment transport. Three empirical functions which relate the equilibrium depth of scour with approach velocity, flow depth, and sediment size, were obtained for uniform sediments. The effects of armouring and sediment sizes were also investigated for nonuniform sediments. (TRRL)
