Shields number versus Froude number for Shi-Wen River using 2-year return period. , in which is bed shear stress, and are sediment and fluid densities, respectively, and is the grain size to be moved multiplied by acceleration due to gravity. The parameter () represents the Froude number, in which is the flow velocity and and are the acceleration due to gravity and flow depth, respectively.
