Stream discharge vs velocity
Webdenotes the distance above the boundary. The fluid velocity at the boundary (y = 0) is zero. At some distance above the boundary the velocity reaches a constant value, U∞, called the free stream velocity. Between the bed and the free stream the velocity varies over the vertical coordinate. The spatial variation of velocity is called shear. http://www.columbia.edu/~vjd1/streams_basic.htm
