Non uniform flow occurs when

the direction and magnitude of the velocity at all points are identical

the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time

velocity, depth, pressure, etc. change from point to point in the fluid flow

the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane
