TEMPLATE FOR DESIGN OF CROSS REGULATOR

How to Use : Input


1 Go to " Input" , fill up data in highlighted cell

2 Click " Design Parameters".

A) Hydraulic Design parameters for cross regulator :

i) Select type of gate.

ii) Enter the size of gate, to see standard size pl. click " Table for gate size ". Click back to
enter the size.
iii) Enter number of gate according to the discharge. According to the number of gate the
message will be displays for drawing. The number and width of pier will displays
automatically.

iv) If the head loss is not provided, then enter the allowable afflux height.

Back v) The crest height should not be less than 0.15 m and more than 40 % of FSD. But in case of
smaller FSD, it may be taken upto 0.05 m.

vi) If the linear waterway check is not satis fied, then change the gate sie, afflux height up to
the desired limit, etc…
vii) Select type of transition. The type of transition will affect the calculated head loss. Hence
select according to the site requirement.

B) Structural Design parameters for cross regulator :

Abutment :

i) Enter the top width of abutment, it should not be less than 0.60 m, and will be in the range
of 0.60 m , 0.75 m and 0.90 m according to the height and span length and stability
consideration.

ii) The top level will be generated automatically.

iii) Enter the foundation level on the basis of trial pit result. The foundation level should be at
least minimum 0.60 m below C.B.L. or below stilling basin Level which ever is lower. And
it should be in the natural firm ground. The foundation should not be kept on the made up
Back ground ( i.e. on embankment ). If the hard rock is mate at the CBL , then the foudation
sould be at CBL, and the bed concrete of 0.30 m depth will be below CBL. The proper
anchoring of abutment with hard rock shall be done. It will be the field officers
resposnsibility to decide the foundation level.

iv) Select the foundation strata on the basis of trial pit result or as per actual excavation.
v) Enter the side slope for stable abutment section upto the "Hence O.K." results.

Warped wall :

Guide wall :

i) Enter the foundation level on the basis of trial pit result. The foundation level should be at
least minimum 0.20 m below C.B.L. or below stilling basin Level which ever is lower.
And it should be in the natural firm ground. The foundation should not be kept on the made
up ground ( i.e. on embankment ). If the hard rock is mate at the CBL , then the foudation
sould be at CBL, and the bed concrete of 0.30 m depth will be below CBL. The proper
anchoring of guide wall with hard rock shall be done. It will be the field officers
resposnsibility to decide the foundation level.

DESIGN OF CROSS REGULATOR :

A) Hydraulic Design :-

0.766

0.566
FSD =

100.150
C.B.L. 100.000 100.000

Step : I : Velocity of Approach

a. Gate size :-

Assume gate size of 0.90 m x 0.90 m ( 2 Nos. )


width Height

b. Width of canal = ( No. of gates x Width of gate ) + width of pier

= 2 x 0.90 + 1.00

= 2.80 m

c. F.S.D on U/S of CR = FSD of canal + Velocity head

0.607 2
= 0.766 +
2 x 9.81

= 0.766 + 0.019

= 0.785 m

d. Area of main canal, A = Total width of canal x FSD on U/S of CR

= 2.80 x 0.785

= 2.20 m2

Q 1.00
e. Velocity of approach,Va = = = 0.455 m/sec
A 2.20

f. Head due to velocity of approach, Ha

Va2 0.455 2
Ha = = = 0.011 m
Ha = = = 0.011 m
2g 2 x 9.81

Step : II : Crest Level of CR :

a. Diffrence of water level above crest, H

U/S F.S.L. = U/S C.B.L. + FSD

= 100.000 + 0.766

= 100.766 m

Head loss provided = 0.05 m

\ D/S F.S.L. = U/S F.S.L. - head loss provided

= 100.766 - 0.05 = 100.716 m

H = U/S FSL - D/S FSL + Velocity head

= 100.766 - 100.716 + 0.019

= 0.069 m

b. Crest level of CR = U/S FSL - Height of gate

= 100.766 - 0.90

= 99.866 m

as per IS 7114-1973 page no. 6, clause No. 3.1.2 for lined canal crest should not be less than
0.15 m or not more than 40% of F.S.D.

Crest Level = 100.000 + 0.15

= 100.150 m

Actual crest level provided = 100.150 m

c. Depth of D/S water in channel above the crest

H2 = D/S FSL - Crest level of CR

= 100.716 - 100.150

= 0.566 m

d. Depth of D/S water in channel above the crest

H1 = U/S FSL - Crest level of CR


= 100.766 - 100.150

= 0.616 m

2
Q = x C1 x Le x H x ( 2 g . H )1/2 +
3

C2 x Le x H2 x ( 2 g . H )1/2

Where,
C1 = coefficient of discharge for freely discharge portion = 0.577
C2 = coefficient of discharge for submerged portion = 0.80
Le = effective linear water way of the opening in 'm'
H = Diff in water level U/S & D/S of channel above crest = 0.069 m
H2 = Depth of D/S Water level in the channel above the crest in m = 0.566 m
\ 1.00 = 2 / 3 x 0.577 x Le x 0.069 x ( 19.62 x 0.069 ) ^0.5 +
0.8 x Le x 0.566 x ( 19.62 x 0.069 ) ^0.5
= 0.031 Le + 0.527 Le
= 0.558 Le
1.00
\ Le = = 1.791 m
0.558
Actual linear water way provided is 1.80 m
Hence 2 gate of 0.9 m x 0.9 m are adequate
Step : IV : Head loss calculations :- As per Govt. circular dated 01/09/2015
i) When the transitions are smooth inlet loss is zero and ‘0.5 x change in velocity head’ at exit. ii)
When transition are abrupt the loss is’ 0.5 x change in velocity head’ at inlet and ‘1.5
x change in velocity head’ at exit.
iii) The losses of head in structure due to friction are negligible and need not be computed.

Consider the transitions are smooth, hence as per above the inlet loss is zero and at exit loss is
" 0.5 x change in velocity head ".

( V22 - V12 )
\ Head loss at entry & exit = K1 + K 2 x
2g
Where,
K1 = constant of kinetic energy head loss at entry = 0
K2 = constant of kinetic energy head loss at exit = 0.5
V1 = velocity of flow in canal on u/s and d/s of structure in m/s = 0.607 m/sec
V2 = velocity of flow in carrier channel of the structure in m/s

Velocity Q 1.00
= = = = 0.901 m/sec
in CR Net Area 1.80 x 0.62

\ Head loss at entry & exit = 0 + 0.5 x
\ Head loss at entry & exit = 0 + 0.5 x 19.62
