A stilling well is required when the stage measurement is made by employing a
In a triangular channel the top width and depth of flow were 2.0 m and 0.9 m respectively. Velocity measurements on the centre line at 18 cm and 72 cm below water surface indicated velocities of 0.60 m/s and 0.40 m/s respectively. The discharge in the channel (in m3/s) is
In the moving-boat method of stream-flow measurement, the essential measurements are
Which of the following instruments in not connected with stream flow measurement?
The surface velocity at any vertical section of a stream is
If a gauging section is having shifting control due to backwater effects, then
The stage discharge relation in a river during the passage of a flood wave is measured. If QR = discharge at a stage when the water surface was rising and QF = discharge at the same stage when the water surface was falling, then
The dilution method of stream gauging is ideally suited for measuring discharges in
