von Karman–Prandtl equation An equation that describes the logarithmic variation of water velocity within a channel from zero flow at the stream bed to a maximum velocity at the water surface. Originally developed in aerodynamics, the equation also describes the profile of wind velocity above the ground. See eddy viscosity.
