We have been going through floods wreaking destruction and drought which cause anguish to the people in different part of India .This is the regular phenomenon due to the disturbance in the natural distribution of the rainfall . In spite of highest rainfall receive in the world , not even one fourth of the water is utilised effectively. The amount of 4,000 billion cubic metres (BCM) of rainfall on an average is receives every year in which 75 per cent is distributed in three monsoon months i.e. summer or pre-monsoon (April to July), Monsoon or rainy (July to September) and Post-monsoon or autumn (October to November) but the intense rainfall occurs only in few hour duration. Approximately about 1,900 BCM of water is available after ground absorption, runoff and evaporation etc and the estimated utilization of water resources is approximately1122 cubic km. So, we are one of the water scared country in the world. If no proper step is being taken for the management and conservation of water then by 2050 we will be starved for water . Keeping this in mind, the government of India has developed a new idea to linked the rivers of India with a canals so that the flooded rivers water can be transfer to those with drought prone region.<\/p>\r\n \r\n\r\nWhat is Inter-Basin Water Transfer<\/strong>\r\n\r\n \r\n

Inter-Basin Water Transfer is a mission to developed or link two or more rivers by constructing a canals manually for diverting the surplus water from one basin to another deficit basin to reduce the water runoff to the sea (Fig.1) . We can also say , transfer of water from flooded Himalayan river to those with drought and scarcity rivers of peninsular India.<\/p>\r\n \r\n\r\n\"\"\r\n

Fig.1.Water Diversion by a Link Canal<\/p>\r\n \r\n\r\nThe need for inter linking of rivers :<\/strong>\r\n\r\n \r\n\r\n1. Regional rainfall variation<\/strong>\r\n\r\n \r\n

\u00a0 \u00a0The distribution pattern of rainfall in India is uneven. There is a large scale spatial-temporal variation of rainfall. During monsoon season ( June to September ) northern and eastern part of the county get maximum rainfall while the western and southern part remain almost dry. Hence, most of the rivers in southern part does not fulfil the demand of the people. On the other hand, Ganga basin and Brahmaputra basin flooded every years and water goes waste in the sea. Therefore inter linking of river will help water scarcity regions to have water throughout the years giving an additional irrigational benefit. And this will controlled the flood in the water surplus rivers and will solve the problem for irrigation and domestic use in drought prone zone in southern part of India.<\/p>\r\n \r\n\r\n2. Irrigation<\/strong>\r\n\r\n \r\n

The demand for food is increasing every year and estimated to double by 2030. It is therefore necessary to increased the area under crop production. The irrigation system in India is mainly through ground water having more than 30 million tube wells. But the decline of ground water table likely reduced the production in the country. The proposed inter linking rivers basin will give benefit for food grain production to the water scarce regions. It is estimated to produce 450 million tonnes of food grain by 2050 in India .<\/p>\r\n \r\n\r\n3. To Control Flood and Drought<\/strong>\r\n\r\n \r\n

Flood are one of the major concerns in Himalayan Rivers particularly in Ganga and Brahmaputra rivers during monsoon seasons. There is causes of huge damages in\u00a0properties and human life every years specially in the states of Assam, Bihar, West Bengal and Uttar Pradesh. On other hand, Southern states of Rajasthan, Andhra Pradesh, Gujarat, Karnataka and Tamil Nadu faces recurring droughts. The interlinking of River basin will transfer the flooded Himalayan river to the water deficient rivers of Peninsular India. This will not only solve the flood and drought problems but also give benefits to millions of people for irrigations and industrial uses.<\/span><\/p>\r\n\r\n

\r\n\r\n\u00a0 \u00a0 \u00a0<\/strong>\r\n\r\n4. Generation of Electric City<\/strong>\r\n\r\n \r\n

The link canal will have a potential to generate electric of about 34000 MW every years with new construction of canals and will be feasible to make more dams. This will help increase the possibility to generate more hydroelectric power . Therefore, the demand for the electricity in many villages will be fulfil.<\/p>\r\n \r\n\r\n5.<\/strong>\u00a0Trade and Transport<\/strong>\r\n\r\n \r\n

The linking of rivers will give benefit for the development of Inland waterways which will help industries to navigate and connect the main industrial centers to transport the goods in more faster way. This mode of transport will help in reducing air pollution, road congestion and road accidents. The beautiful en-route scenic will be an addition for the development of tourism industry.<\/p>\r\n \r\n\r\n6.\u00a0Income Generation<\/strong>\r\n\r\n \r\n

Diverting the surplus water to the deficient region will give a new occupation for the people living in the en-route command area of the link canals. This will give more opportunities like fishing, boating and increase in agriculture area utilizing the irrigation infrastructure available. This will also open up many new routes and ways giving rise to water navigation systems which will connect many region with more efficient and cheaper rate as compare to roadways. Thus, it will lead to development of Tourist Industries.<\/p>\r\n \r\n\r\nHistory of Indian River Linking:<\/strong>\r\n\r\n \r\n

The proposal for Inter linking the rivers of India started in 19th century when Sir Arthur Cotton a British India government and an engineer by profession during the British colonial rule recommended for the first time to connect major rivers channels to solved the scarcity of water and drought in south eastern part of the country and embark upon transport of goods in South Asia. Later on , Dr. K .L. Rao in 1960s who was then a irrigation minister projected an idea of linking Ganga and Cauvery with a 2640 km long canal which he called as \u201cNational<\/em> Water Grid\u201d. <\/em>His idea was to link 14 major Indian rivers to divert the surplus water from Northern India to deficit area of south east part of India taking into six components. Which are :<\/p>\r\n\r\n<\/div>\r\n

\r\n\r\n \r\n\r\n \r\n

The proposed link canal would required to pump 26 billion cumecs of flood water from Ganga near Patna with a maximum lift of 550m heights during the monsoon. Approximately 5 to 7 million kW of power is required to transfer 1,800-3,000 cumecs of water from Brahmaputra \u2013 Ganga link to Cauvery link by lifting upto the height of 12-15m. However, his proposal was not accepted due to the heavy cost and huge power requirement.<\/p>\r\n \r\n

Retired Captain Dinshaw J. Dastur a Pilot in 1972, suggested a \u2018Garland Canal\u2019 scheme which include 4200 km long Himalayan canal and 9,332 km long Garland canal in peninsular India. According to his proposal , 14 canals is required to link Ganga and Brahmaputra from west to east of about 2,400 km long along the Himalayas and 1,770 km towards the south. It is therefore a long canal of 9,332 km is needed to link central and Southern region. However , his proposal could not be implemented due to the heavy investment and unsound technology. But if executed, then it will be the largest inter-basin transfer of water in the world giving a additional irrigational benefit to the water deficit region and it might produced a power of about 35 GW .<\/p>\r\n \r\n

In 1982 , The Ministry of Water Resources and National Water Development Authority (NWDA) developed a feasibility report called \u201cNational Perspectives for Water Resources Development\u201d. The outlined of the Perspectives consists of two components i.e the Himalayan components and Peninsular components ( Fig.2) . However , the plan was abandoned till the commission for Integrated Water Resources Development carried out a detailed study in 1999.<\/p>\r\n \r\n

In October 2002 ,the Supreme Court of India mandated that the Central Government to complete the project to link Himalayan river component to peninsular river component to provide water to the drought stricken region of India. A committee was setup under the leadership of former President Dr.A.P.J.Abdul Kalam and Prime Minister Sh.Atal Bihari Vajpayee. A detailed report were prepared to link 26 Indian major rivers by constructing 30 different link canals. The project were to begin immediately with the date line by 2016. But only six links have been completed so far and it has been disbanded after the resignation of Mr.Prabhu from the leadership .<\/p>\r\n\r\n<\/div>\r\n\"\"\r\n

Himalayan Rivers Development component ( Fig.3) consists construction of dams and storage reservoirs along the Ganga and the Brahmaputra rivers in India, Nepal and Bhutan. This will transfer the surplus water from the eastern Ganga river through a canal to the west . Further Brahmaputra river and its tributaries will again linked to Ganga river and from Ganga to the Mahanadi river. This project will provide a additional irrigation benefit to about 220,000 sq. km of area and also generate electricity to support the local demand on en - route area. This link canal will provide inland waterway for easy and fast movement of goods. This will further provide excess water discharge for the controversial Farakka Barrage to flush out the silt at Kolkatta port.<\/p>\r\n\r\n<\/div>\r\n\"\"\r\n

Kosi \u2013 Mechi link canal will divert surplus water from Kosi river to the Mahanadi river. The Canal will takeoff from exiting Hanuman Nagar Barrage on Kosi River. The total length of the canal is 112.55 km long crossing many rivers like Bakra , Ratuwa and Kankai before falling into river Parman and Mechi ( Fig.4). The canal required lifting of water through aqueduct tube before merging with Mechi river due the topography features of the region. It passes through Terai region of Nepal. This will provide irrigation facilities to the area of about 4.74 lakh hectare lying in the channel such as Araria , Kishanganj, Purnia and Katihar District of Bihar. And this will also provide navigational facility from Chatra to Ganga via Mechi and Mahananda rivers.<\/p>\r\n\r\n<\/div>\r\n\"\"\r\n

Jogighopa - Tista - Farakka Link Canal take off from proposed Johighopa barrage which will divert the deficient water from Brahmaputra through a gravity link canal and travel in the western and southern parts of the country to meet the water shortages (Fig.14). The proposed link canal has water dispute with China and Bangladesh. Therefore, it is examined by international team and concluded that the link was not feasible due to the major problem of the soils. The soils in the en route of the canal which is to be excavated were prone to liquefaction in earthquakes. The earthquakes in Assam in 1954 has the same reason.<\/p>\r\n \r\n\r\n\"\"\r\n\r\n \r\n

The main objectives of linking peninsular rivers is to divert surplus water from Mahanadi and Godavari basins to the surplus basins of peninsular by inter- linking with canals. This link canal will serve the demand of power and irrigation for the domestic need in the en-route command area. But this interlinking will require to construct a numbers of big canals and large dam. It will also require lifting of water in some places which will involve huge financial and sound technical inputs. This inter-linking project will be one of the challenging and ambitious project.<\/p>\r\n \r\n\r\n\"\"\r\n

Godavari \u2013 Krishna link canal is propose to transfer surplus water of Mahanadi and Godavari river basin to Krishna river basin. The 299.256 km long link canal including 9 km long tunnel originate from Inchampalli reservoir, falling into many major rivers (Akeru ,Palleru and Musi ) before merging with Nagarjunasagar reservoir vie Musi reservoir. The en-route of the canal mostly passes through agricultural fields , only about 35 kms passes through the dense forest in the starting.<\/p>\r\n \r\n

Due to topographic obstacles, the link canal would be require to lift in four stages upto the height of 35, 38, 23 and 11 m respectively for which about 1,705 MW of power would be needed. The total diversion of water through this link canal is 16426 Mm3 and around 1664 Mm3 will be used in an en route for the irrigational , domestic and industries in Khammam, Warangal and Nalgonda districts of Andhra Pradesh and rest will be delivered to Nagarjunasagar reservoir in Krishna Rivers.<\/p>\r\n \r\n\r\n3.<\/strong>\u00a0Godavari (Inchampalli) \u2013 Krishna (Pulichintala) Link<\/strong>\r\n\r\n \r\n

The water is further supplies to the Vaippar basin through the 9 km long to cross the hilly terrain of western ghats in Tamil Nadu.The total length of 50.68 km long main canal will connect Alagar Odai (tributary of Vaippar river).<\/p>\r\n \r\n\r\nIssue and Problems<\/strong>\r\n\r\n \r\n

Inter-Linking of Rivers ( ILR) Project in India is challenging and complicated issues related to geo-politics , social, economic and ecological. The project has international and national dispute . It will have an impact on neighbouring countries like Nepal, Bhutan and Bangladesh. Bangladesh have already protest on the diversion of substantial amount of Brahmaputra water to the south west part of India to connect with Cauvery river. As it will change the ecosystem of the region making it into dry and drought prone area. Interstate dispute on water sharing is also one of the most important subject . The three main interstate dispute on water sharing are :<\/p>\r\n \r\n

The Krishna-Godavari water dispute is between the state of Maharashtra, Karnataka, Andhra Pradesh (AP), Madhya Pradesh (MP), and Odisha) and the issue on the utilization of surplus water.<\/p>\r\n \r\n

The Cauvery water dispute is between Karnataka and Tamil Nadu on the re-sharing of waters .<\/p>\r\n \r\n

The Ravi-Beas water dispute is between Punjab , Haryana and Rajasthan for the utilisation of water for irrigation benefit .<\/p>\r\n \r\n

The basic concept for Inter-Linking of Rivers is to transfer surplus flood waters to the deficient and needed regions. But during the monsoon season , deficient rivers will not require the additional water. So construction of enormous reservoirs is needed. Which will required a huge financial . The maintenance of the huge assets and electric power generation for pumping the water to a different height will also involve huge financial burdens. And to envisages the project construction of dams , canals , tunnels is require which will affect the peoples and submerge the forest in an en-route command area. So , the Union ministry of environment and forests has already said no to the project. Because rehabilitation of the project affected region will be a major issues.<\/p>\r\n \r\n\r\nAdvantage of Inter \u2013Linking of River (ILR)<\/strong>\r\n

    \r\n \t
  1. Inter \u2013linking of rivers will help deficient drought prone region to have water throughout the year .<\/li>\r\n \t
  2. It will give additional irrigation benefit and create potential to increase production in agriculture sectors.<\/li>\r\n \t
  3. Floods in the Ganga and Brahmaputra river basins will be controlled by transferring the surplus water to the deficient rivers of peninsular .<\/li>\r\n \t
  4. Scarcity of water in southern India will be solve .<\/span><\/li>\r\n \t
  5. Generation of new occupation<\/span><\/li>\r\n \t
  6. Facilitation of Inland waterways through the large linking canals<\/span><\/li>\r\n \t
  7. Large income generation<\/span><\/li>\r\n<\/ol>\r\n<\/div>\r\n \r\n\r\nDisadvantage of Inter-Linking of Rivers ( ILR)<\/strong>\r\n
      \r\n \t
    1. Inter \u2013 linking of rivers will cause huge lost to the environment . The whole ecosystem will change due to the mass deforestation for the construction of the dams and canals.<\/li>\r\n \t
    2. Resettlement of a people to the en-route command area is not an easy task.<\/li>\r\n \t
    3. Practically the project will not last for a longer period due to the frequent changes in the river course .<\/li>\r\n \t
    4. The amount of pollution in the river may increase as the flood flush the pollution down to the ocean but diversion will increase the amount of concentration in the rivers<\/li>\r\n \t
    5. The amount of fresh water entering into the seas will reduced which will cause a major ecological disturbance in the marine ecosystem .<\/li>\r\n \t
    6. Total cost of these projects is very huge that the government will have to depend on foreign sources which can fall in a dept trap.<\/li>\r\n \t
    7. Political relation with the neighbouring countries may disturbed due to the water sharing dispute.<\/li>\r\n<\/ol>\r\nAlternatives to Indian River Linking<\/strong>\r\n\r\n \r\n\r\nConservation of Water Resources and Rainwater Harvesting Recharging Ground Water<\/strong>\r\n\r\n \r\n\r\nCommunity Participation<\/strong>\r\n\r\n \r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n
