INTRODUCTION 1. Demand for electricity in India outstrips supply. Inadequate generation, transmission, and distribution, and less-than-optimum use of electricity, lead to shortages, particularly at peak times. In 2006–2007, India had a peak power deficit of 13.5% and a power supply deficit of 9.9%; the corresponding deficits in the Northern region were 11.3% and 10.9%, respectively.1 The total national shortfall in 2006 was estimated to be 8.3% of demand.2 According to the 2001 census, about 44% of households in India have no access to electricity. Recognizing that electricity is a key driver of rapid economic growth and poverty reduction, the Government aspires to meet electricity demand in full by 2012.3 Other objectives include providing all households with access to electricity within 5 years, and increasing the per capita availability of electricity to over 1,000 kilowatt-hours (kWh) by 2012. 2. India generates about 83% of its electricity from thermal power plants and about 14% from hydroelectric plants.4 Installing a combination of generation types would enable the country to meet the substantial demand for electricity, but the Government is seeking to increase the share of hydropower generation to 50,000 megawatts (MW) of hydroelectric projects to deliver renewable energy benefits. Uttarakhand, now a net importer of electricity, plans to be a net exporter by 2010. The state has little or no fossil fuel resources, but has abundant hydropower potential, given its river resources and range of elevation. Of its assessed hydropower potential of 18,175 MW, only 6% had been developed by 2004. 3. NTPC Limited is implementing the 520 MW Tapovan–Vishnugad Hydroelectric Project (HEP) and the 600 MW Loharinag–Pala HEP, run-of-river schemes in Uttarakhand with some similar features. The construction of the Loharinag–Pala HEP began in July 2006; the first turbine is scheduled to be commissioned in April 2011 and the final turbine will come online in October 2011. The construction of the Tapovan–Vishnugad HEP began in November 2006; the first turbine is scheduled to be commissioned in September 2012 and the final turbine in March 2013, but efforts are being made to commission the Project by March 2012. These projects will add 1,120 MW of installed capacity to the Indian grid—a substantial contribution to meeting the shortfall in supply. 4. As required by the Government, environmental impact assessments (EIAs), covering the construction and operation of the projects, were prepared. A rapid EIA (March 2004) and a comprehensive EIA (September 2004) were prepared for each project. Detailed project reports were also prepared in March 2004 for the Loharinag–Pala HEP, and in April 2004 for the Tapovan–Vishnugad HEP. A detailed socioeconomic survey of all project-affected families, consisting of a village survey and a household survey, was completed in August 2005 for the Loharinag–Pala HEP, and in December 2005 for the Tapovan–Vishnugad HEP. 5. All necessary national and state government approvals for both projects have been obtained. The Ministry of Environment and Forests (MOEF) granted NTPC final site clearance (Stage II) for the Loharinag–Pala HEP in January 2004, and for the Tapovan– Vishnugad HEP in February 2004. These clearances permitted NTPC to carry out a site survey and investigation and to collect environmental data for the EIA and the Environmental Management Plan. Site clearances also permitted the construction of roads and temporary residences. However, if the area affected by these developments was on forest land, then prior clearance was required under the Forest (Conservation) Act, 1980. 1 Central Electricity Authority.

Public hearings were held—in July 2004 for the Loharinag–Pala HEP, and in August 2004 for the Tapovan–Vishnugad HEP—and no-objection certificates for the projects were issued by the Uttaranchal Environment Protection and Pollution Control Board in September 2004.

    South Asia Network on Dams, Rivers and People Uttarakhand: Existing, under construction and proposed Hydropower Projects: How do they add to the disaster potential in Uttarakhand? As Uttarakhand faced unprecedented flood disaster and as the issue of contribution of hydropower projects in this disaster was debated, one question for which there was no clear answer is, how many hydropower projects are there in various river basins of Uttarakhand? How many of them are operating hydropower projects, how many are under construction and how many more are planned? How projects are large (over 25 MW installed capacity), small (1-25 MW) and mini-mirco (less than 1 MW installed capacity) in various basins at various stages. This document tries to give a picture of the status of various hydropower projects in various sub basins in Uttarakhand, giving a break up of projects at various stages. River Basins in Uttarakhand Entire Uttarakhand is Uttarakhand has 98 operating hydropower part of larger Ganga basin.

    IOSR Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT) e-ISSN: 2319-2402,p- ISSN: 2319-2399.Volume 9, Issue 2 Ver. II (Feb 2015), PP 28-35 www.iosrjournals.org Interlinking of rivers in India: Proposed Sharda-Yamuna Link Anjali Verma and Narendra Kumar Department of Environmental Science, Babasaheb Bhimrao Ambedkar University (A Central University), Lucknow-226025, (U.P.), India. Abstract: Currently, about a billion people around the world are facing major water problems drought and flood. The rainfall in the country is irregularly distributed in space and time causes drought and flood. An approach for effective management of droughts and floods at the national level; the Central Water Commission formulated National Perspective Plan (NPP) in the year, 1980 and developed a plan called “Interlinking of Rivers in India”. The special feature of the National Perspective Plan is to provide proper distribution of water by transferring water from surplus basin to deficit basin. About 30 interlinking of rivers are proposed on 37 Indian rivers under NPP plan. Sharda to Yamuna Link is one of the proposed river inter links. The main concern of the paper is to study the proposed inter-basin water transfer Sharda – Yamuna Link including its size, area and location of the project. The enrouted and command areas of the link canal covers in the States of Uttarakhand and Uttar Pradesh in India. The purpose of S-Y link canal is to transfer the water from surplus Sharda River to deficit Yamuna River for use of water in drought prone western areas like Uttar Pradesh, Haryana, Rajasthan and Gujarat of the country.

  • Source of the Sacred Ganges with Shadow of the Mighty Shivling
    SOURCE OF THE SACRED GANGES WITH SHADOW OF THE MIGHTY SHIVLING This trek and tour visits a remote and highly spectacular part of the Indian Himalaya. Garhwal, celebrated in Hindu mythology and religion is locally known as the ‘Abode of the Gods’. In this massif, beyond the Hindu shrine at Gangotri, the mighty Ganges River has its source. Emerging from a glacier, this great river rushes down to the plains in a torrential flurry. Our itinerary includes two short treks. The first trek is a warm up and takes us off the beaten track from the small village of Raithal to Dayara Bugyal “Nature's Own Gardens” and Bakaria Top for great panoramic views of the Garhwal Himalaya. We then move on to Gangotri where the trek starts from Gangotri Temple, dedicated to Mother Goddess Ganga on the bank of Bhagirathi River which is the main tributary of Ganga River. Winding through Bhojbasa, Gaumukh source of the Sacred Ganges, and continue trek to The massif overlooks the sprawling meadow of Tapovan at 4,463 meters, which is considered as one of the alpine meadows in India and is crisscrossed by several small streams and dotted with flowering plants. And where Shivaling and other mighty peaks are almost close enough to touch. We also visit the holy town of Haridwar where the River Ganges exits the Himalayan foothills, Rishikesh on the banks of the Ganges located in the foothills of the Himalayas in northern India, it is known as the 'Gateway to the Garhwal Himalayas' and 'Yoga Capital of the World'.

  • Earthquakes, Dam Design and Tehri Project* by C.D
    Earthquakes, Dam Design And Tehri Project* by C.D. Thatte** DAMS AND THEIR DESIGN PHILOSOPHY ROLE PLAYED BY DAMS AND RESERVOIRS Dams have been built across rivers by mankind right from the dawn of civilisation for storing the river flow during rainy season and r~leasing it during the remaining part of year for either domestic use or for irrigation. Flood control has been another important function of these dams. While releasing water from the storages, hydroelectric energy is also generated. With the growth of population all these functions of dams and storages have assumed great significance and hence every civilisation has tried to keep pace with the needs ofthe society for food, energy, fibre and well being through this activity of water resources development. INPUTS FOR SAFE DESIGN Dams constitute perhaps the largest and the most complex of structures being built by civil engineers. Basic input of water is dependent on nature, so also the river course, its history, its underlying strata and its stability. Assessment of the variability of these natural phenomena and providing for it in the design of a dam, has been an important challenge for the dam builders. The dams are built to last from 100 to 300 years depending upon merits of each case. During their service life, they are designed to withstand all the possible destabilising forces with a certain factor of safety which has been an indicator of a factor of ignorance or lack of knowledge of various response processes of materials used in construction, the stresses caused, the strains experienced and finally the failure mechanism.

  • Uttarakhand Flash Flood
    Uttarakhand Flash Flood drishtiias.com/printpdf/uttarakhand-flash-flood Why in News Recently, a glacial break in the Tapovan-Reni area of Chamoli District of Uttarakhand led to massive Flash Flood in Dhauli Ganga and Alaknanda Rivers, damaging houses and the nearby Rishiganga power project. In June 2013, flash floods in Uttarakhand wiped out settlements and took lives. Key Points Cause of Flash Flood in Uttarakhand: It occurred in river Rishi Ganga due to the falling of a portion of Nanda Devi glacier in the river which exponentially increased the volume of water. Rishiganga meets Dhauli Ganga near Raini. So Dhauli Ganga also got flooded. Major Power Projects Affected: Rishi Ganga Power Project: It is a privately owned 130MW project. Tapovan Vishnugad Hydropower Project on the Dhauliganga: It was a 520 MW run-of-river hydroelectric project being constructed on Dhauliganga River. Several other projects on the Alaknanda and Bhagirathi river basins in northwestern Uttarakhand have also been impacted by the flood. 1/4 Flash Floods: About: These are sudden surges in water levels generally during or following an intense spell of rain. These are highly localised events of short duration with a very high peak and usually have less than six hours between the occurrence of the rainfall and peak flood. The flood situation worsens in the presence of choked drainage lines or encroachments obstructing the natural flow of water. Causes: It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields. Flash Floods can also occur due to Dam or Levee Breaks, and/or Mudslides (Debris Flow).

  • Melt Water Characteristics of Gangotri Glacier, Headwater of Ganga River Manohar Arora* & Jatin Malhotra National Institute of Hydrology, Roorkee, Uttarakhand, India
    Roorkee Water Conclave 2020 Melt Water Characteristics of Gangotri Glacier, Headwater of Ganga River Manohar Arora* & Jatin Malhotra National Institute of Hydrology, Roorkee, Uttarakhand, India Abstract: Behavior of glacier plays an important role in runoff delaying characteristics of the glacier. Changes in delaying characteristics of the runoff over the melt season can be understood by studying the variation in time to peak (tp) and time-lag (t1) between melt generation and its emergence as runoff. In this study, the runoff delaying characteristics of the Gangotri Glacier in the Garhwal Himalayas (glacierized area 286 km2; drainage area 556 km2) have been studied. For this purpose, hourly discharge and temperature data were monitored near the snout of the glacier for the entire ablation period (May-October, 2010). In the early stages of the ablation period, poor drainage network and stronger storage characteristics of the glaciers due to the presence of seasonal snow cover resulted in a much delayed response of melt water, providing a higher tl and tp. In the beginning of melt season, the night time flow is almost equal to day time flow, but in the later part of the melt season, night time flow is slightly lower than the day time flow. This analysis suggests that storage characteristics are much stronger in the early part of melt season and reduce as the melt season progresses. Keywords: Gangotri Glacier, Himalayas, Melt Season, Runoff Delay Characteristics, Storage Characteristics 1. Introduction Glaciers fed rivers provide much of the water supply in some parts of the world. All the major south Asian rivers originate in the Himalayan and their upper catchments are covered with snow and glaciers.
