If the depth of flow in a channel is 1 m and velocity of the flow is 2 m/sec, then the velocity at which elementary wave can travel upstream is:
- A4.132 m/sec
- B3.132 m/sec
- C2.132 m/sec
- D1.132 m/sec

Velocity at which elementary wave can travel upstream (Vu/s) = C – V
Where,
C = celerity = $(\sqrt {gy} )$
y = depth of flow
C = $(\sqrt {9.81 \times 1} = 3.132\;m/s)$
Vu/s = 3.132 – 2 = 1.132 m/s
Where,
C = celerity = $(\sqrt {gy} )$
y = depth of flow
C = $(\sqrt {9.81 \times 1} = 3.132\;m/s)$
Vu/s = 3.132 – 2 = 1.132 m/s
