So we decided to take visit in Sardar Sarovar Narmada dam, near Navagam. 3 GENERAL INFORMATION Narmada Dam & sardar sarovar are one of the largest water resources of India covering four major states - Maharashtra, Madhya Pradesh, Gujarat and Rajasthan. Dam's spillway discharging capacity is 30.7 lakhs cusecs. Narmada Main Canal' s length is 532 km and it is the largest irrigation canal in the world with 1133 cumecs (40000 cusecs) capacity at the head regulator. 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. 4 PURPOSE OF VISIT Our main purpose for this visit is to be familiar with industrial environment and to get practical knowledge of Hydraulic structure of dam and Hydro power plant in dam. Also in 5th semester subject like Irrigation engineering requires knowledge about how components of dam and hydro power plant are constructed, so it is very much convenient to see all the practical and components in real time work environment. 5 LEARNING POINT On 23rd September, at 09:00 am we reached at narmada dam. We started the visit from statue of unity, and than we visited RBPH, Narmada Dam, CHPH, Narmada Main Canal. Statue of unity 6 The visit started from Statue of Unity which is under construction monument dedicated to Indian independence movement leader Vallabhbhai Patel. The construction work for statue was running. It is 182m high, made of steel framing and reinforced concrete. The museum of Shree Sardar Vallabhbhai Patel will also constructed near statue of unity. 7 RBPH (The River Bed Power House ) After statue of unity we visited RBPH. The RBPH (River Bed Power House) is undeer ground Power house which was constructed at 165 m downstream of the dam. RBPH has installed capacity of 1200 MW with six number of Francis type reversible turbine generators each of 200 MW installed capacity. 8 Narmada Dam Sardar Sarovar Dam is a concrete gravity dam across river Narmada, 1210 meters (3970 feet) in length and with a maximum height of 163 meters above the deepest foundation level, is constructed up to the crest level of spillway i.e. 121.92 m. In terms of the volume of concrete involved for gravity dams, this dam is ranked as the second largest in the world with an aggregate volume of 6.82 million cu.m. 9 This dam with its spillway discharging capacity of 87,000 cumecs (30.70 lac) is the third in the world. CHPH The CHPH is a surface power station on right bank of the reservoir having total installed capacity of 250 MW (5 x 50 MW). These units can be operated with minimum reservoir water level of 110.18 meters. 10 Narmada Main Canal The Narmada Main Canal, having a length of 458 km in Gujarat and further extended to 74 km in Rajasthan, is world’s largest concrete lined canal with discharge carrying capacity of 1133 m3 /second (40,000 cusecs) at its head. Narmada Main Canal is a contour canal. At full supply depth, this canal can store 220 MCM of water. The Main Canal is lined with plain cement concrete to minimize seepage losses to attain higher velocity and to control the water logging in future. The lining work is carried out with the mechanized pavers. 11 Such a large scale paving of concrete lining is done for the first time in India. The ogee fall is provided in downstream side to discharge the excess water during flood. 12 CONCLUSION From this visit, we get the information and knowledge about the components of dam, hydro-power plant and its construction. Students got very clear idea about the importance of different components of dam. 13 Thank You Department of Civil Engineering 14.

  • Resettlement in Narmada River Basin Evolution of Resettlement Policy in India
    Resettlement in Narmada River Basin Evolution of Resettlement Policy in India Uday Shelat Professor, Department of Architecture and Planning The Maharaja Sayajirao University of Baroda, India Abstract The present paper examines the problems of resettlement of people affected by a large-scale water resource development project in India. At present there is no resettlement policy at the national level, but the Government of Gujarat has evolved resettlement policies for the Saradar Sarovar Project on the river Narmada. The attempt has been made to look into the policies, strategies and implementation process i.e., efforts made by the state government to resettle the project-affected people in the new habitats. Finally, the paper depicts recommendations and suggestions to strengthen the resettlement process. Introduction India after independence embarked on an ambitious programme of economic development. Nation faced twin problems of unemployment and poverty to begin with. The land was rich with diverse natural resources but was unharnessed. The crucial task was to channelize these resources- land, water, minerals, forests, and sea wealth so as to transform them into productive wealth for the people. India has unique geographic situation where arable land is spread out stretching from Kutch to Brahmputra valley and from Deccan trap to plains of Punjab, while bulk of surface water sources are concentrated in about dozen river basins; and 80% of surface water is available only in monsoon months which flows down the sea if not impounded. Therefore neither water nor land is utilised optimally, depriving the country of their full benefits. The Saradar Sarovar Project (SSP) on river Narmada was conceived keeping these potentials.

Research Article QUANTITATIVE ASSESSMENT OF COASTAL CHANGES BETWEEN NARMADA AND KIM RIVER OF SOUTH GUJARAT, INDIA Janak P Joshi1, Sumit Dabral2 and *Bindu Bhatt2 1Department of Geography, the Maharaja Sayajirao University of Baroda 2NHPC Ltd., Tawang Hydro-Electric Project Stage I, Nehru Market, District: Tawang – 790104, Arunachal Pradesh, India *Author for Correspondence ABSTRACT Coastal areas are very important for human beings since the beginning of time. Change detection is the process of identifying differences in the state of an object or phenomenon by observing it at different times. Coastal changes are attracting more focus since they are important environmental indicators that directly impact coastal economic development and land management. Both natural and anthropogenic processes along the coast control the erosion, and accretion activities of the coastal zones The study quantifies the changes along the Coast between Narmada and Kim River of South Gujarat, India by using geospatial techniques. The analysis of the multi-temporal remote sensing data shows that the coast is subject to important changes during years between 1978-2011 time interval including erosion and accretion. The study also demonstrates the applicability and efficacy of geospatial technique for quantitative assessment and monitoring of the coastal environment. Key Words: Quantitative, Erosion, Accretion, Coastal Region, Geospatial INTRODUCTION Coastal zone is the transition area between land and ocean Aidy et al., (2007) and is an area of complex, dynamic and delicate environment.

  • 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).

  • 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.
