Shear velocity is a form by which a shear stress may be re-written in units of velocity. This is typically done when solving problems of shear stress distributions in fluids; this is often solved in relation to problems of sediment transport.

$u_\left\{star\right\}=sqrt\left\{frac\left\{ au_b\right\}\left\{ ho$

Where $au_b$ is the shear stress given at a boundary (this is the common, though not necessary, usage), and $ho$ is the density of the fluid.
