Problems and scope of improvement in the project area
The socio economic conditions of the area can be improved through increased production which can be achieved through expansion in cultivated
area and productivity enhancement. 1626.736 ha land is arable wasteland and 1193.10 ha is fallow can be brought under cultivation.
1211 ha is only irrigated and with efforts this can be increased to1500 ha. The productivity gap of major crops in the area as compared with
district and with areas in the same agro climatic zones indicate potential to increase the productivity. The demonstration of improved package of
practices, improved varieties, increased irrigation facilities and soil conservation measures under the project can bridge this gap. Due to small
land holdings in the area focus of the project would be on diversification in agriculture (horticulture, vegetables, green houses, Agro forestry,
fodder crops)and diversification in Livelihoods(Agriculture, Animal husbandry, self employment)
46620.50 Quintal fodder scarcity can be met out through Pasture development .Improved animal Husbandry practices can increase the
productivity of livestock. 537 No of persons migrate due to unemployment. This migration can be checked through creation of employment
opportunities in the project area through increase in production and diversification in agriculture and Livelihoods as mentioned above.

CHECKS FOR AGAINST OVER TURNING , RUPTURE FROM TENSION , SLIDING &
CRUSHING
H = 1.00 meter
h = 1.60 meter
Tw = 1.50 meter
Bw = 2.28 Kg \cum
Specific weight of masonary s = 2300.00 Kg \cum
Specific weight of water w = 1000.00 Kg \cum
Coefficient of uplift c = 0.50
Coefficient of friction f = 0.75
Weight of structure W = W1 + W2
W1 = s x Tw x H = 3450.00 Kg
W2 = s x H( Bw - Tw ) / 2 = 897.40 Kg
W = W1 + W2 = 4347.40 Kg
Water pressure at depth H = P1
P1 = w x h = 1600.00 Kg \ sqm
Water pressure at depth (H+h)=P2
P2= w x ( H + h ) = 2600.00 Kg \ sqm
Net Horizontal water force =
( P1 + P2 ) / 2 x H = 2100.00 Kg \ sqm
Force due to water at the crest
F3 = w x h x Tw = 2400.00 Kg/m
Up lift pressure U1=c x w x (h+H)= 1300.00 Kg/sqm
Up lift Force =U = U1 x Bw / 2 = 1482.23 Kg/m
1. Safty against Over turning
Taking moment of all the forces about the toe of the Structure
Restoring Moment, RM = W1 x(Bw- Tw/2)+W2 x (Bw - Tw ) x 2 / 3 +F3 (Bw - Tw/2)
RM = 9419
Over turning Moment, OM=Fa x H/2 + Fb x H/3 + U x2 Bw/3
Where Fa = P1 x H = 1600
Fb = (P2- P1)/2 x H = 500
OM = 3220
RM / OM = 2.93
It is more than 1.30, so the structure is safe against overturning.
2. Safty against tension at the base
The excess moment , Em=( RM - OM) 6199
Total Vertical Force, V = W + F3 - U= 5265.18
X represents the position of the resultant force from top of the structure.
X = Excess moment / Total vertical force
X = 1.18
Which is more than Bw / 3 = 0.76 of the structure ,
& less than 2Bw/3= 1.52
i.e. Resultant is passing through the middle 1 / 3 of the base so there is no chance of developing any tension in maonary. Hence the structure is safe against Rupture from Tension.
3. Safty against Compression (Crushing)
Ecentricity e = Bw / 2-X
where x =(RM-OM)/ V 1.18
so e = -0.04
Fmax = V(1+6e/Bw)/A = 2082.56
In order to avoid crushing of the masonary at the base Fmax. is maximum compressive stress acting normal to the base of the structure. It is less than the Max.allowable compressive stress for the masonary 20000 Kg / sqm. Hence Safe against Crushing.
4. Safty against sliding
Total Vertical Force, V =W+F3-U= 5265.18
Resisting forces, P = f V + ChA = 3949.79
Sliding forces = Fa + Fb = 2100
Factor of safety for sliding
= Restoring force / Sliding force P/V= 1.88
It is more than 1.3, so the structure is safe against Sliding.

P2= w x ( H + h ) = 2600.00 Kg \ sqm
Net Horizontal water force =
( P1 + P2 ) / 2 x H = 2100.00 Kg \ sqm
Force due to water at the crest
F3 = w x h x Tw = 2400.00 Kg/m
Up lift pressure U1=c x w x (h+H)= 1300.00 Kg/sqm
Up lift Force =U = U1 x Bw / 2 = 1482.23 Kg/m
1. Safty against Over turning
Taking moment of all the forces about the toe of the Structure
Restoring Moment, RM = W1 x(Bw- Tw/2)+W2 x (Bw - Tw ) x 2 / 3 +F3 (Bw - Tw/2)
RM = 9419
Over turning Moment, OM=Fa x H/2 + Fb x H/3 + U x2 Bw/3
Where Fa = P1 x H = 1600
Fb = (P2- P1)/2 x H = 500
OM = 3220 RM / OM = 2.93
It is more than 1.30, so the structure is safe against overturning.
2. Safty against tension at the base
The excess moment , Em=( RM - OM) 6199
Total Vertical Force, V = W + F3 - U= 5265.18
X represents the position of the resultant force from top of the structure.
X = Excess moment / Total vertical force
X = 1.18
Which is more than Bw / 3 = 0.76 of the structure ,
& less than 2Bw/3= 1.52
i.e. Resultant is passing through the middle 1 / 3 of the base so there is no chance of developing any tension in maonary. Hence the structure is safe against Rupture from Tension.
3. Safty against Compression (Crushing)
Ecentricity e = Bw / 2-X
where x =(RM-OM)/ V 1.18
so e = -0.04
Fmax = V(1+6e/Bw)/A = 2082.56
In order to avoid crushing of the masonary at the base Fmax. is maximum compressive stress acting normal to the base of the structure. It is less than the Max.allowable compressive stress for the masonary 20000 Kg / sqm. Hence Safe against Crushing.
4. Safty against sliding
Total Vertical Force, V =W+F3-U= 5265.18
Resisting forces, P = f V + ChA = 3949.79
Sliding forces = Fa + Fb = 2100
Factor of safety for sliding
= Restoring force / Sliding force P/V= 1.88
It is more than 1.3, so the structure is safe against Sliding.

(i) Head over the crest
Q = c x L x h 3/2
h3/2 = Q / (c xL ) 1.70 meter
So h = 1.43 meter
Say h = 1.50 meter
( ii ) Free board
F = 1.5 hw , Where hw is the height of wave hw = 0.014 (Df)

Bw = 2.19 Kg \cum
Specific weight of masonary s = 2300.00 Kg \cum
Specific weight of water w = 1000.00 Kg \cum
Coefficient of uplift c = 0.50
Coefficient of friction f = 0.75
Weight of structure W = W1 + W2
W1 = s x Tw x H = 3220.00 Kg
W2 = s x H( Bw - Tw ) / 2 = 911.54 Kg
W = W1 + W2 = 4131.54 Kg
Water pressure at depth H = P1
P1 = w x h = 1500.00 Kg \ sqm
Water pressure at depth (H+h)=P2
P2= w x ( H + h ) = 2500.00 Kg \ sqm
Net Horizontal water force =

Force due to water at the crest
F3 = w x h x Tw = 2100.00 Kg/m
Up lift pressure U1=c x w x (h+H)= 1250.00 Kg/sqm
Up lift Force =U = U1 x Bw / 2 = 1370.40 Kg/m
1. Safty against Over turning
Taking moment of all the forces about the toe of the Structure
Restoring Moment, RM = W1 x(Bw- Tw/2)+W2 x (Bw - Tw ) x 2 / 3 +F3 (Bw - Tw/2)
RM = 8423
Over turning Moment, OM=Fa x H/2 + Fb x H/3 + U x2 Bw/3
Where Fa = P1 x H = 1500
Fb = (P2- P1)/2 x H = 500
OM = 2920
RM / OM = 2.88
It is more than 1.30, so the structure is safe against overturning.
2. Safty against tension at the base
The excess moment , Em=( RM - OM) 5503
Total Vertical Force, V = W + F3 - U= 4861.14
X represents the position of the resultant force from top of the structure.
X = Excess moment / Total vertical force
X = 1.13 Which is more than Bw / 3 = 0.73 of the structure ,
& less than 2Bw/3= 1.46
i.e. Resultant is passing through the middle 1 / 3 of the base so there is no chance of developing any tension in maonary. Hence the structure is safe against Rupture from Tension.
3. Safty against Compression (Crushing)
Ecentricity e = Bw / 2-X
where x =(RM-OM)/ V 1.13
so e = -0.04
Fmax = V(1+6e/Bw)/A = 2000.73
In order to avoid crushing of the masonary at the base Fmax. is maximum compressive stress acting normal to the base of the structure. It is less than the Max.allowable compressive stress for the masonary 20000 Kg / sqm. Hence Safe against Crushing.
4. Safty against sliding
Total Vertical Force, V =W+F3-U= 4861.14
Resisting forces, P = f V + ChA = 3646.73
Sliding forces = Fa + Fb = 2000
Factor of safety for sliding
= Restoring force / Sliding force P/V= 1.82
It is more than 1.3, so the structure is safe against Sliding.

W = W1 + W2 = 4347.40 Kg

Water pressure at depth (H+h)=P2
P2= w x ( H + h ) = 2600.00 Kg \ sqm

Up lift Force =U = U1 x Bw / 2 = 1482.23 Kg/m
1. Safty against Over turning
Taking moment of all the forces about the toe of the Structure
Restoring Moment, RM = W1 x(Bw- Tw/2)+W2 x (Bw - Tw ) x 2 / 3 +F3 (Bw - Tw/2)
RM = 9419
Over turning Moment, OM=Fa x H/2 + Fb x H/3 + U x2 Bw/3
Where Fa = P1 x H = 1600
Fb = (P2- P1)/2 x H = 500
OM = 3220 RM / OM = 2.93
It is more than 1.30, so the structure is safe against overturning.
2. Safty against tension at the base
The excess moment , Em=( RM - OM) 6199
Total Vertical Force, V = W + F3 - U= 5265.18
X represents the position of the resultant force from top of the structure.
X = Excess moment / Total vertical force
X = 1.18
Which is more than Bw / 3 = 0.76 of the structure ,
& less than 2Bw/3= 1.52
i.e. Resultant is passing through the middle 1 / 3 of the base so there is no chance of developing any tension in maonary. Hence the structure is safe against Rupture from Tension.
3. Safty against Compression (Crushing)
Ecentricity e = Bw / 2-X
where x =(RM-OM)/ V 1.18
so e = -0.04
Fmax = V(1+6e/Bw)/A = 2082.56
In order to avoid crushing of the masonary at the base Fmax. is maximum compressive stress acting normal to the base of the structure. It is less than the Max.allowable compressive stress for the masonary 20000 Kg / sqm. Hence Safe against Crushing.
4. Safty against sliding
Total Vertical Force, V =W+F3-U= 5265.18
Resisting forces, P = f V + ChA = 3949.79
Sliding forces = Fa + Fb = 2100
Factor of safety for sliding
= Restoring force / Sliding force P/V= 1.88
It is more than 1.3, so the structure is safe against Sliding.

Up lift Force =U = U1 x Bw / 2 = 1482.23 Kg/m
1. Safty against Over turning
Taking moment of all the forces about the toe of the Structure
Restoring Moment, RM = W1 x(Bw- Tw/2)+W2 x (Bw - Tw ) x 2 / 3 +F3 (Bw - Tw/2)
RM = 9419
Over turning Moment, OM=Fa x H/2 + Fb x H/3 + U x2 Bw/3
Where Fa = P1 x H = 1600
Fb = (P2- P1)/2 x H = 500
OM = 3220 RM / OM = 2.93
It is more than 1.30, so the structure is safe against overturning.
2. Safty against tension at the base
The excess moment , Em=( RM - OM) 6199
Total Vertical Force, V = W + F3 - U= 5265.18
X represents the position of the resultant force from top of the structure.
X = Excess moment / Total vertical force
X = 1.18
Which is more than Bw / 3 = 0.76 of the structure ,
& less than 2Bw/3= 1.52
i.e. Resultant is passing through the middle 1 / 3 of the base so there is no chance of developing any tension in maonary. Hence the structure is safe against Rupture from Tension.
3. Safty against Compression (Crushing)
Ecentricity e = Bw / 2-X
where x =(RM-OM)/ V 1.18
so e = -0.04
Fmax = V(1+6e/Bw)/A = 2082.56
In order to avoid crushing of the masonary at the base Fmax. is maximum compressive stress acting normal to the base of the structure. It is less than the Max.allowable compressive stress for the masonary 20000 Kg / sqm. Hence Safe against Crushing.
4. Safty against sliding
Total Vertical Force, V =W+F3-U= 5265.18
Resisting forces, P = f V + ChA = 3949.79
Sliding forces = Fa + Fb = 2100
Factor of safety for sliding
= Restoring force / Sliding force P/V= 1.88
It is more than 1.3, so the structure is safe against Sliding.

Force due to water at the crest
F3 = w x h x Tw = 2100.00 Kg/m
Up lift pressure U1=c x w x (h+H)= 1250.00 Kg/sqm
Up lift Force =U = U1 x Bw / 2 = 1370.40 Kg/m
1. Safty against Over turning
Taking moment of all the forces about the toe of the Structure
Restoring Moment, RM = W1 x(Bw- Tw/2)+W2 x (Bw - Tw ) x 2 / 3 +F3 (Bw - Tw/2)
RM = 8423
Over turning Moment, OM=Fa x H/2 + Fb x H/3 + U x2 Bw/3
Where Fa = P1 x H = 1500
Fb = (P2- P1)/2 x H = 500
OM = 2920 RM / OM = 2.88
It is more than 1.30, so the structure is safe against overturning.
2. Safty against tension at the base
The excess moment , Em=( RM - OM) 5503
Total Vertical Force, V = W + F3 - U= 4861.14
X represents the position of the resultant force from top of the structure.
X = Excess moment / Total vertical force
X = 1.13
Which is more than Bw / 3 = 0.73 of the structure ,
& less than 2Bw/3= 1.46
i.e. Resultant is passing through the middle 1 / 3 of the base so there is no chance of developing any tension in maonary. Hence the structure is safe against Rupture from Tension.
3. Safty against Compression (Crushing)
Ecentricity e = Bw / 2-X
where x =(RM-OM)/ V 1.13
so e = -0.04
Fmax = V(1+6e/Bw)/A = 2000.73
In order to avoid crushing of the masonary at the base Fmax. is maximum compressive stress acting normal to the base of the structure. It is less than the Max.allowable compressive stress for the masonary 20000 Kg / sqm. Hence Safe against Crushing.
4. Safty against sliding
Total Vertical Force, V =W+F3-U= 4861.14
Resisting forces, P = f V + ChA = 3646.73
Sliding forces = Fa + Fb = 2000
Factor of safety for sliding
= Restoring force / Sliding force P/V= 1.82
It is more than 1.3, so the structure is safe against Sliding.

1. Safty against Over turning
Taking moment of all the forces about the toe of the Structure
Restoring Moment, RM = W1 x(Bw- Tw/2)+W2 x (Bw - Tw ) x 2 / 3 +F3 (Bw - Tw/2)
RM = 9419
Over turning Moment, OM=Fa x H/2 + Fb x H/3 + U x2 Bw/3
Where Fa = P1 x H = 1600
Fb = (P2- P1)/2 x H = 500
OM = 3220 RM / OM = 2.93
It is more than 1.30, so the structure is safe against overturning.
2. Safty against tension at the base
The excess moment , Em=( RM - OM) 6199
Total Vertical Force, V = W + F3 - U= 5265.18
X represents the position of the resultant force from top of the structure.
X = Excess moment / Total vertical force
X = 1.18
Which is more than Bw / 3 = 0.76 of the structure ,
& less than 2Bw/3= 1.52
i.e. Resultant is passing through the middle 1 / 3 of the base so there is no chance of developing any tension in maonary. Hence the structure is safe against Rupture from Tension.
3. Safty against Compression (Crushing)
Ecentricity e = Bw / 2-X
where x =(RM-OM)/ V 1.18
so e = -0.04
Fmax = V(1+6e/Bw)/A = 2082.56
In order to avoid crushing of the masonary at the base Fmax. is maximum compressive stress acting normal to the base of the structure. It is less than the Max.allowable compressive stress for the masonary 20000 Kg / sqm. Hence Safe against Crushing.
4. Safty against sliding
