1. PRESENTATION
ON
GULF OF KHAMBHAT DEVELOPMENT PROJECT(WR)
Kalpasar as a prospective Water solution
- Saurashtra
A Truly Matchless Project

2. MISSION

3. VISION
To create world’s 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
State’s average annual rain water inflow.

Note : As per M. Falkenmark if renewable freshwater availability falls below 1000 M 3 per
capita, water supply begins to hamper health, economy growth and human well being.

9. Why Project is required ?

10. 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 water
availability is only 540 M3/annum against 1700
m3/annum minimum requirement.
4. In Saurashtra region,only 15 lakh ha
agricultural 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. 5. The excessive pumping of groundwater resulted
in intrusion of saline water up to 10 km of entire
coastal 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.

18. Estimated Cost of the Project
• Earlier the dam was envisaged between Ghogha
to Hansot having length of 64 km. wherein tidal
power component was combined alongwith
development of fresh water reservoir in the Gulf.
• As per pre-feasibility report of the project, the
cost 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 cost
works out to approximate Rs.1,40,000 crore, in
which the tidal power component is Rs.86,000
crore.

19. • 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.

20. Benefits of the Project

21. GULF OF KHAMBHAT DEVELOPMENT PROJECT (W.R.)
Irrigation Benefit

22. Irrigation Benefit
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 60
existing dams as well as check dams,
tidal regulators, spreading channels
permanently.

23. Perceived Agricultural Benefits

24. Transportation Benefits

25. Transportation Benefit
• Substantial saving in travel time and fuel due
to reduction in distance by about 200 km
between Bhavnagar and Surat.
• Surat is one of the fastest growing city in the
country and the diamond oriented business
hub of the world.
• Most of the diamond workers (more than 10
lakhs) are migrated from Saurashtra (Mostly,
from Bhavanagr, Amreli district).

26. • After the completion of dam and Bhadbhut
Barrage, the route from Bhavnagar to Surat
will be Bhavnagar—Dahej—Hansot—Olpad—
Surat.
• 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 the
dam. 75000 vehicles per day is estimated for
year 2020, and 1,00,000 vehicles per day for
year 2030.

27. • The toll-tax generation is estimated
approximately 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. Land Reclamation Benefits
• Gulf of Khambhat is one of the Gulf in world
having maximum tide of 11 m and the average
tide 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.

30. Land recovery (As per BISAG Study)

31. Value Addition Of Land
Projects in vicinity of Kalpasar project
• Dholera SIR
• Fedara International Airport
• PCPIR at Dahej
• SEZ, GIDC etc.
• Delhi- Mumbai Industrial Corridor

32. • Proposed 10 lane road for Ahmedabad-
Bhavnagar route
• 2000 sq. km world’s biggest fresh water
reservoir (in sea) with 6-lane periphery road of
270 km long
• Solar and Wind power, Tourism, Bio-fuel park,
Transportation, Fisheries etc. project
components / benefits

33. Benefit -Reduction in Salinity
In coastal region of Saurashtra and
Central Gujarat, saline ground water
will be converted into sweet water,
resulting reduction in inland salinity

34. Benefit- Port Development on
d/s of Dam
Project presents highly attractive locational
attributes for port development downstream of
the dam such as increased water level, lower
current velocity, reduced sedimentation

35. 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 a
maximum reduction at Dahej and Gogha.
Bhavnagar port will be rejuvenated, therefore
this region will be speedily developed

36. Benefits- Generation of
Non-conventional Energy
Wind and solar power would be
generated which will also be used for
lifting of fresh water of reservoir.

37. Wind Energy
Wind energy is planned to be used for
pumping of irrigation water. Approximately
250 crore unit will be required for lifting
irrigation water. As per Suzlon study, 1600
MW with an estimated cost of about Rs. 9000
crore can be generated by installing wind
mills/ solar units. Wind mill will have added
benefit of its installation after dam
construction.

38. 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.
