Shear velocity, often denoted as \( u_* \) (u-star), is a measure of the frictional velocity in a fluid, typically used in contexts related to turbulence, boundary layer flows, and sediment transport. It describes the velocity scale associated with the shear stress near a boundary (like the surface of the Earth or a water body) that influences the motion of particles and the behavior of the flow.
