Web2 de jan. de 2024 · Turbulent shear stress can cause sediment bedload transport and hence channel erosion . Channel erosion can pose a long-term risk to the safety of in … WebBecause the shear stress is constant, the momentum flux rho u(*)(2) is equal to the wall shear stress, so u(*) is often understood as some kind of synonym for the wall shear stress. The universal Log-law is also used for the flows with linear shear stress such as pipe flows and uniform open channel flows.
