WebThe delayed-flow index for a given N (DFI N) is then calculated as the ratio of the sum of delayed flow to the sum of total streamflow. N=0 represents the case of no separation, and the delayed-flow series is set equal to the streamflow series (DFI 0 =1). For N=1 the DFI value will be slightly less than 1 as some peaks in the hydrograph will be ...

In this state soil exerts no resistance to flow and shear deformations. Soil flows …
In continuum mechanics, a power-law fluid, or the Ostwald–de Waele relationship, is a type of generalized Newtonian fluid (time-independent non-Newtonian fluid) for which the shear stress, τ, is given by $${\displaystyle \tau =K\left({\frac {\partial u}{\partial y}}\right)^{n}}$$where: K … See more Pseudoplastic, or shear-thinning are those fluids whose behaviour is time independent and which have a lower apparent viscosity at higher shear rates, and are usually solutions of large, polymeric molecules in a … See more Just like a Newtonian fluid in a circular pipe gives a quadratic velocity profile (see Hagen–Poiseuille equation), a power-law fluid will result in a power-law velocity profile, See more • Power law • Rheology • Navier–Stokes equations See more A Newtonian fluid is a power-law fluid with a behaviour index of 1, where the shear stress is directly proportional to the shear rate: See more Dilatant, or shear-thickening fluids increase in apparent viscosity at higher shear rates.
