Q(m3/sec) = f.b(meter).
<.75 = .45,
.75-1.5 = .60,
1.5-85.0 = .75,
>85 = .90.

If Free Board is 90cm than discharge will be greater than 85 cumecs (>85cumecs). i.e, F.B. =90cm than, Q is > 85cumecs.

All 4 are true that means. Then why above 60 cumecs? Explain.

Discharge(cumecs) => extent of freeboard(m).
1 to 5. => 0.50,
5 to 10 => 0.60,
10 to 30 => 0.75,
30 to 150 => 0.90.
1 to 5. => 0.50,
5 to 10 => 0.60,
10 to 30 => 0.75,
30 to 150 => 0.90.
