Various methods for determination of shear velocity and bed shear stress in hydraulic research are discussed, comprising gravity method, logarithmic profile method, near-bed Reynolds-stress method, turbulent kinetic energy method, Prandtl based method, Saint Venant method, power law method, pipe flow method, Shields method, and direct methods. These methods are, where applicable, used to estimate shear velocity and/or bed shear stress in different fields of hydraulic research, ranging from flows in compound channels, gravel bed rivers, and cohesive sediment erosion studies to flows under unsteady conditions.
