Vertical Velocity Distribution in Open-Channel Flow with ...

Velocity Profile. The vertical distribution of velocity with rigid vegetation could be divided into two layers: the upper nonvegetated layer (>1.0 Hv) and the lower rigid vegetated layer (0-1.0 Hv). The upper nonvegetated layer is from the rigid rod top (1.0 Hv) to the water surface. The lower layer is from the bed to water surface.

Fluid velocity in a vertical pipe - Physics Stack Exchange

What will happen is that the stream diameter will become smaller to account for the faster velocity. If the water were a bar of elastic material this would be the same as stretching it. It's mass flow is the same, it just elongates as it becomes faster. By the time it reaches the bottom of the vertical pipe the stream will not have a diameter of A.
