DEPARTMENT: ELECTRICAL Date: 19/10/2016-20/10/2016, Wednesday-Thursday Duration: 2 Day Venue: D-Cabin Road, Near Ram Wadi, Nava yard, Chhani Jakat Naka Circle, Vadodara, Gujarat, India-391740. Department : Electrical Department Students No. of Students Present: 31 Submitted by: Mr.Savan R.Thacker The Narmada River It is the largest westward flowing river in India. It is starting from amarkantak rock which is situated near at Jabalpur in Madhya Pradesh. Its coverage area is Chhattisgarh, Madhya Pradesh and Gujarat. It is 1300k.m long and at last is meet to the Arabian Sea near Bharuch. Its branch river length is around 200k.m. There was many dams are constructed on the Narmada river. Like Bargi, Tawa, Narmada Sagar, Omkareshwar, Maheshwar and Sardar. 1 Introduction about Sardar sarovar Dam The Sardar Sarovar Dam is a gravity dam on the Narmada river near Navagam, Gujarat in India. It is the largest dam and part of the Narmada Valley Project, a large hydraulic engineering project involving the construction of a series of large irrigation and hydroelectric multi-purpose dams on the Narmada river. The project took form in 1979 as part of a development scheme to increase irrigation and produce hydroelectricity. One of the 30 dams planned on river Narmada, Sardar Sarovar Dam (SSD) is the largest structure to be built. Following a number of controversial cases before the Supreme Court of India (1999, 2000, 2003), by 2014 the Narmada Control Authority had approved a series of changes in the final height – and the associated displacement caused by the increased reservoir, from the original 80 m (260 ft) to a final 163 m (535 ft) from foundation. The project will irrigate more than 18,000 km2 (6,900 sq mi), most of it in drought prone areas of Kutch and Saurashtra. The dam's main power plant houses six 200 MW Francis pump-turbines to generate electricity and include a pumped-storage capability. Additionally, a power plant on the intake for the main canal contains five 50 MW Kaplan turbine-generators. The total installed capacity of the power facilities is 1,450 MW. Its final configuration is the second largest concrete gravity dam after Grand Coulee Dam in the US and has the world's third largest spillway discharging capacity. Reservoir Full reservoir level: 138.68 m. Maximum water level: 140.21 m. Minimum draw down level: 110.64 m. Normal tail water level: 25.91 m. 2 Submergence at F.R.L 138.68 m: 34867 ha.

  • A Case Study of Gujarat State, India Dr
    The role of water technology in development: a case study of Gujarat State, India Dr. Rajiv Kumar Gupta, IAS, Government of Gujarat, Republic of India Type of tool: technology Location: Gujarat State, India Introduction This article traces the historical water problem in Gujarat both for drinking and irrigation that affected the development of the State, caused regional imbalances and increased incidence of rural poverty. Technological initiatives like the State Wide Water Grid, Micro Water Harvesting, Inter-Basin Transfer of Water and Power Sector Reforms have changed the entire water scenario in the State. There has been a great deal of emphasis on peoples’ participation in water governance as well. Water challenges in Gujarat Gujarat has just 2.28% of India’s water resources and 6.39% of country’s geographical area. This is again constrained by imbalances in intra-state distribution. The State has an average annual rainfall of 80 cm with a high coefficient of variance over time and space and as a result droughts have been frequent. Out of 185 rivers, the State has only eight perennial rivers and all of them are located in southern part. Around 80% of the State’s surface water resources are concentrated in central and southern Gujarat, whereas the remaining three-quarters of the State has only 20%. On average, three years in a cycle of 10 years have been drought years. Since Indian independence in 1947, the drought years of Gujarat have been as follows: 1951, 1952, 1955, 1956, 1957, 1962, 1963, 1965, 1968, 1969, 1972, 1974, 1980, 1985, 1986, 1987, 1991, 1999, 2000 and 2003 (Gupta, 2004).

During this period, the TISS developed baseline data on social, demographic, economic, cultural and environmental aspects of individuals, families and communities in 33 villages in Akkalkuwa and Akrani tehsils of Dhule (now Nandurbar) district, and tracked changes in the habitat and life conditions of people shifted from Manibeli, Dhankhedi, and Chimalkhedi villages to Parveta (one of the earliest resettlement sites in Gujarat). While TISS moved out of its monitoring and evaluation role in 1994, it continued to track the progress made on various aspects of the SSP. Dam height has been steadily increasing and reached 121.92 m in October 2006; the final and pending phase of installing radial gates will take the dam height to 138.68 m.

  • 1 India's Sardar Sarovar Project
    India’s Sardar Sarovar Project (SSP) (Unpublished 2003 T.Scudder Manuscript) Introduction During the 1980s, my major river basin fieldwork aside from Kariba concerned India’s Sardar Sarovar (SSP) and China’s Three Gorges Projects. Along with the binational Lesotho Highlands Water Project where I began annual visits in 1989, and the Accelerated Mahaweli Project, these projects are among the largest undergoing construction during the initial years of the 21st century. As with the Aswan High Dam, my assessment will emphasize resettlement aspects, but with one major difference. In the High Dam case, a credible and relatively successful resettlement process was completed. In the Sardar Sarovar case, the refusal of the project authorities at the central and state levels to plan and execute even a minimal resettlement program has become the main constraint to project implementation as well as the focal point at the national and international levels for a globally relevant dialogue on opposing development paradigms. As initially planned the key feature of SSP was to be a 138 meter high dam across the Narmada River in eastern Gujarat that is to provide irrigation water for 1.8 million hectares and have hydropower installed capacity of 1,450 megawatts. How what the Indians refer to as Resettlement and Rehabilitation 1 was to be carried out was stipulated by the 1979 report of the Narmada Water Disputes Tribunal (the Tribunal). Because the project authorities have ignored the Tribunal’s provisions from the start, opposition began to build up in the early and mid 1980s. Several NGOs were involved. Initially their main concern was to improve the resettlement process according to the Tribunal and the guidelines of the World Bank.

Anklesaria Aiyar and Neeraj Kaushal NBER Working Paper No. 24423 March 2018 JEL No. H1,H13,H75,I0 ABSTRACT The Sardar Sarovar Dam in Gujarat is arguably the most controversial dam ever built in India, with over a 100,000 displaced people. Most ousted families in Gujarat were resettled in the late 1980s and early 1990s. All oustees were tribals—a term used in India to cover a list of tribes viewed as so backward and historically oppressed that the Indian Constitution in 1950 reserved a quota of seats in education, government jobs, and Parliamentary seats for them.

  • The Sardar Sarovar Dam Project: Selected Documents Level
    Chapter 1 The Sardar Sarovar Dam Project: An Overview Philippe Cullet The Sardar Sarovar Project (SSP) is part of a gigantic scheme seeking to build more than 3,000 dams, including 30 big dams, on the river Narmada, a 1,312 km river flowing westwards from Amarkantak in Madhya Pradesh, touching Maharashtra and ending its course in Gujarat. The SSP is a multi-purpose dam and canal system whose primary rationale is to provide irrigation and drinking water. Power generation is another expected benefit. It is the second biggest of the proposed dams on the Narmada, and its canal network is projected to be the largest in the world. The dam is situated in the state of Gujarat, which will derive most of the benefits of the project, but the submergence – 37,533 hectares in total – is primarily affecting the state of MP (55 per cent) and to a much lesser extent the state of Maharashtra. The SSP has been one of the most debated development projects of the past several decades in India and at the international level. It is only one of many similar big projects in the Narmada valley and in India generally but it has acquired a symbolic status in development debates. This is due in part to the complexity of such multi-purpose projects and the multiple positive and negative impacts associated with big dams. This is also due to the specificities of this project, which was first proposed nearly 60 years ago. Firstly, the fact that this project involves four states – Gujarat, MP, Maharashtra and Rajasthan – with the state of Gujarat receiving most of the benefits of the project has repeatedly led to disagreements among the concerned states.
