1 Hydraulic Design :-
Flood discharge as per dicken's formula.
Q = C x A 3/2
Q = 1800 x( 0.12 )3/4
Q = 360.5 cusec
Q = 10.2 Cumec

Area required for opening
Assume Valocity of nalla limited to 3.00 meter/ sec.
A = Q / V
= 11.00 / 3.00
= 3.667 sqm say 4 sqm
Assume box size = 2.00 x 2.00 meter
Area of box = 4 sqm
Nos. of opening required = 4 / 4
