  1. PRESENTATION ON GULF OF KHAMBHAT DEVELOPMENT PROJECT(WR) A Truly Matchless Project

  2. Geographical Location of Project

  3. MISSION

  4. VISION & PLANNING To create world’s largest fresh water reservoir in sea to store state’s 25% average annual surface water resources by constructing 30 km long dam across the Gulf of Khambhat. This reservoir will store 10500 MCM of surface water.

  5. Surface Water Availability in State Population –year 2011 (India 1230 million) Geographical Area (India 3065000 sq.km) Gujarat State 5.0% (60.3 million) Surface Water Availability (India -18,69,000 MCM) Gujarat State 6.39% (196024 sq.km) Gujarat State 2.0%(38,000 MCM)

  6. Per Capita Water Availability in India & Gujarat

  7. Per Capita Availability of Water (Year 2011)

  8. Region wise Water Resources in Gujarat State

  9. Need of the Project

  10. Gujarat is a water scarce state, with 6.39% of geographical area, 5% of population & only 2% of water resources of India. 71% of water resources of Gujarat is available in 25% of geographical area of central & south Gujarat. In Saurashtra region, per capita water availability is only 540 M3/annum against 1700 m3/annumminimum requirement. 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. The excessive pumping of groundwater resulted in intrusion of saline water up to 10 km of entire coastal belt of Saurashtra. The rain water storage capacity of Gujarat state is 20480 Mm3 in 196 major &medium reservoirs, against the total rainwater availability of 38000 MCM per annum. Due to 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.

  12. Salient features (Tentative)

  13. Benefits of the Project

  14. Irrigation Benefit

  15. 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.

  16. PerceivedAgricultural Benefits

  17. Transportation Benefits

  18. Detail of Road Route Existing Route New Route Dam Alignment

  19. Transportation Benefit • Substantial saving in travel time and fuel due to reduction in distance by about 136 km between Bhavnagar and Surat/ Mumbai. • 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).

  20. 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. 70,118 vehicles per day is estimated for year 2025, and 2,07,529 vehicles per day for year 2055. • The toll-tax generation is estimated approximately Rs. 1035 crore for year 2025 and Rs. 8257 crore for year 2055.

  21. 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. • As per present planning, the fresh water reservoir have Full reservoir level at +3.0 m and maximum water level (during flood) is +5.0 m.

  22. Land Reclamation Benefits • Hence, the land which is frequently submerged during high tide between permanently opened above EL +5.0 m after closure of the Gulf of Khambhat • About 2 lakh ha land along the periphery of reservoir will be opened which can be used for the project development.

  23. Land Reclamation Benefits

  24. Land recovery (As per BISAG Study)

  25. Value Addition Of Land • Pipeline Important Projects Vicinity • Dholera SIR • Fedara International Airport • PCPIR at Dahej • Delhi- Mumbai Industrial Corridor • (2) Proposed 10 lane road for Ahmedabad-Bhavnagar route

  26. 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

  27. Ground Water Quality Improvement Due to sea water ingress in rivers upto 60 to 70 km, total peripheral ground water in 7,00,000 ha of Bhavnagar, Ahmedabad, Kheda, Anand, Vadodara and Bharuch district has became saline. After post dam scenario, due to only fresh water in rivers / catchment, this saline ground water quality with improve some time.

  28. 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

  29. TIDE RANGES WITH AND WITHOUT DAM

  30. CURRENT SPEED WITH AND WITHOUT DAM

  31. NIO MODEL STUDY • Model study results show that after the construction of the dam the tide level increases at all the port locations. • The currents decrease at the locations near to the dam (Bhavnagar, Ghoga). • 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

  32. Wind and Solar Energy As per Suzlon Company’s observations for more than one year of two wind mast, the wind velocity more than 6 m/sec & density 200 watt / sq.m is available in periphery of fresh water reservoir. Suzlon has proposed three wind farm clusters of 2.1 MW, 700 wind turbines generators (1470 MW), which will generate 250 crore unit of electricity which will be sufficient for lifting 10,000 Mm3 water from reservoir.

  33. Wind and Solar Energy Total 4500 ha land will be required for erection of 1470 MW wind towers against that 2 lac ha land will be recovered. Wind farms will be installed after completion of dam on Public Private Partnership & the same land will be used for 800MW to 1000 MW solar panels. Hybrid model has been envisaged to get electricity for 8 to 9 months in a year.

  34. Wind & Solar Park

  35. 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.

  36. OTHER BENEFITS • Supply of 900 MCM fresh water for domestic use • Supply of 500 MCM fresh water for industrial use • Tourism • Navigation
