MISSION


3/39

VISION

To create worlds largest fresh water reservoir

in sea, by constructing 30 km long dam in the

Gulf of Khambhat, to store more than 10,000

MCM of surface water, i.e. 25% of volume of

States average annual rain water inflow.

Note : As per M. Falkenmark if renewable freshwater availability falls below 1000 M3 per

capita, water supply begins to hamper health, economy growth and human well being.

Per Capita Availability of Water (Year 2001)

10/39

1. Gujarat is a water scarce state, with 6.39% of

geographical area, 5% of population & only 2%

of water resources.2. 71% of water resources available in 25% of

geographical area of central & south Gujarat.

3. In Saurashtra region per capita wateravailability is only 540 M3/annum against 1700

m3/annumminimum requirement.

4. In Saurashtra region,only 15 lakh haagricultural land will cover under irrigation

(including Sardar Sarovar Project), against 42

lakh ha agricultural land. Hence, 27 lakh ha

agricultural land will remain rainfed.


11/39

5. The excessive pumping of groundwater resulted

in intrusion of saline water up to 10 km of entirecoastal belt of Saurashtra.

6. The water storage capacity of Gujarat state is

20480 Mm3 in 196 medium & major reservoirs,

against the total rainwater availability of 38000

MCM per annum.

7. Non availability of any suitable site for major

irrigation scheme in the state, the Gulf of

Khambhat Development Project is the only

option available to store 10,000 MCM rainwater.

rejuvenate, Dahej port will be

outside of reservoir, New

ports are proposed at downstream of dam.

reservoir

Sabarmati, Mahi, Dhadhar,

Narmada (through diversion

canal), Limbadi Bhogavo,Sukhbhadar, Utavali, Keri,

and Vagad

12 Construction of dam 5 to 7 years


18/39

Earlier the dam was envisaged between Ghogha

to Hansot having length of 64 km. wherein tidalpower component was combined alongwith

development of fresh water reservoir in the Gulf.

As per pre-feasibility report of the project, thecost of project was estimated of Rs. 53,000 crore

(base year 1998) in which the tidal power

component was Rs.33000 crore. Considering,

average 8% inflation per annum present costworks out to approximate Rs.1,40,000 crore, in

which the tidal power component is Rs.86,000

crore.

Estimated Cost of the Project


19/39

Recently, tidal power component is delinked

from the project and the dam alignment is

shifted northward by 15 km, leads to reduction

of length of dam from 64 km to 30 km & height of

dam is also reduced from 55 m to 35 m.

Considering above the approximate project cost

at present is Rs. 50,000 to 60,000 crore.

Benefits of the Project


21/39

GULF OF KHAMBHAT DEVELOPMENT PROJECT (W.R.)

Irrigation Benefit


22/39

10.54 lakh ha. land in 39 talukas of 6

districts of Saurashtra region will get

irrigation facilities including rejuvenation

of rivers and filling of more than 60existing dams as well as check dams,

tidal regulators, spreading channels

permanently.

Irrigation Benefit


23/39

PerceivedAgricultural Benefits


24/39

Transportation Benefits


25/39

Substantial saving in travel time and fuel dueto reduction in distance by about 200 km

between Bhavnagar and Surat.

Surat is one of the fastest growing city in thecountry and the diamond oriented business

hub of the world.

Most of the diamond workers (more than 10lakhs) are migrated from Saurashtra (Mostly,

from Bhavanagr, Amreli district).

Transportation Benefit


26/39

After the completion of dam and Bhadbhut

Barrage, the route from Bhavnagar to Surat

will be BhavnagarDahejHansotOlpadSurat.

New coastal highway will be developed to

connect present petro-chemical hub Hazira(Surat) to future petro-chemical hub PCPIR

(Dahej).

10 lane road is proposed on the top of thedam. 75000 vehicles per day is estimated for

year 2020, and 1,00,000 vehicles per day for

year 2030.


27/39

The toll-tax generation is estimatedapproximately Rs. 1500 crore for year 2020

and Rs. 2000 crore for year 2030.

Considering 10% I.R.R., Capital investment of

Rs.15,000 crore to Rs. 20,000 crore may likely

available from transport component (30% to

40% cost of the project)


28/39

Gulf of Khambhat is one of the Gulf in world

having maximum tide of 11 m and the averagetide of 8.8 m .

During the high tide and flood in Narmada, Mahi,

Sabarmati river etc., the sea water rise up to

level of +7.0 m to +8.0 m from MSL.

After closure of the Gulf of Khambhat, land

which is frequently submerged during high tide

will be permanently opened.

About 1.5 to 2 lakh ha land along the periphery

of reservoir will be opened which can be used

for the project development.

components / benefits


33/39

In coastal region of Saurashtra and

Central Gujarat, saline ground water

will be converted into sweet water,

resulting reduction in inland salinity

Benefit -Reduction in Salinity


34/39

Benefit- Port Development on

d/s of DamProject presents highly attractive locational

attributes for port development downstream of

the dam such as increased water level, lowercurrent velocity, reduced sedimentation


35/39

NIO MODEL STUDY

i. Model study results show that after the

construction of the dam the tide level

increases at all the port locations.

i. The currents decrease at the locations near

to the dam (Bhavnagar, Ghoga).

i. Sediment transport results indicate that the

sediment concentration reduces in the

southern gulf (outside the dam) with amaximum reduction at Dahej and Gogha.

Bhavnagar port will be rejuvenated, therefore

this region will be speedily developed


36/39

Wind and solar power would begenerated which will also be used for

lifting of fresh water of reservoir.

Benefits- Generation ofNon-conventional Energy


37/39

Wind Energy

Wind energy is planned to be used forpumping of irrigation water. Approximately

250 crore unit will be required for lifting

irrigation water. As per Suzlon study, 1600MW with an estimated cost of about Rs. 9000

crore can be generated by installing wind

mills/ solar units. Wind mill will have addedbenefit of its installation after dam

construction.


38/39

Benefits-fisheries Development

Fish production to the tune of 3,00,000

tonnes per annum amounting to Rs.22,500

Million at full development stage

Direct employment to approximately 1,00,000

beneficiaries and indirect employment to

approximately 3,00,000 beneficiaries.
