IIINNTTRROODDUUCCTTIIIOONN Geographically Uttarakhand is situated between 28 43’45” to 31 8’10” N latitude and 77 35’5” to 81 2’25” E longitude. For administrative purpose Uttarakhand state is divided into 13 districts (Fig 1). According to the Census of India, 2001 the population of the state is 84,89,349, which is 0.8 per cent of the total population of India. People of all faiths – Hindu, Muslims, Christians, Sikhs and Bodhs – live in the state, though majority of population is of Hindu faith. The present project, Alaknanda Hydro-electric project (300 MW) is located in Joshimath tehsil of Chamoli district in Uttarakhand. The total population of Joshimath tehsil is 39,919 (Census, 2001). There are around 16 villages in the vicinity of the Alaknanda H.E. project (within 10 km radius from the project sites). These villages fall under six revenue villages, namely Khirao, Mana, Badrinath, Lambagar, Binayak Chatti and Pandukeshwar. Only Khirao is directly affected due to the different project activities . 1.1 Salient Features of Alaknanda H.E. Project The 300 MW Alaknanda H. E. project is proposed on Alaknanda River. Alaknanda H.E. Project is proposed to be a Run of the River scheme. The project propose to generate 300 MW of power and involves construction of a 18 m high diversion barrage across the Alaknanda river 3 km downstream of Badrinath town. The 2.87 km long headrace tunnel will be of a horseshoe shape and 4.3 m dia and an underground power house is proposed near Khirao Ganga (Fig. 2). The tail water will be discharged through an underground tail water tunnel upstream of tail of reservoir of under operation Vishnuprayag H. E. project. The salient features of the project are given in Table 1. Table 1. Salient features of Alaknanda H.E. project 1.

PPHHYYSSIIIOOGGRRAAPPHHYY The physiography of a river basin refers to the sculptures on the land surface developed by various geomorphic processes which are controlled by the prevalent climate and the internal dynamism of the earth. The Alaknanda and Saraswati valleys are U-shaped in the initial stretches; a typical feature of glaciated valleys. There are ice pinnacles, rocky knobs, moraines, cirque glaciers, valley glaciers, talus cones in the catchment of Alaknanda river. Huge dumps of rock fragments at the base of hill slopes or valley side floors, known as scree fans, is one of the most common features observed above 4,000 m. Alaknanda river has two major tributaries, the Saraswati draining the Arwa valley and Dhauliganga coming from Niti Pass. Alaknanda river originates at the water divide between Satopanth and Bhagirath glaciers (near Vashundhara Falls), flows eastward and joins Saraswati river at Mana and then flows in a SE direction up to Joshimath where it meets Dhauliganga. After this confluence, it takes a swerve and starts flowing in the SW direction to meet Bhagirathi river at Devprayag. The drainage network of the Alaknanda watershed up to the proposed barrage site is shown in Fig. 3. River Sarswati is a major tributary of Alaknanda, which receives Arwa Nala, Nagthuni Gad and Anadeb EXECUTIVE SUMMARY CISMHE Gad from left bank. In the downstream of Saraswati confluence, the river Alaknanda is joined by Kanchan Ganga at 2970 m from left bank. The first right bank tributary is Rishi Ganga. It flows eastward and confluences with Alaknanda river on its right bank near Badrinath at 2,960 m near Bamni village. Two streams from Dhamling Dhar region joined Alaknanda at 3,020 and 2,950 m respectively on the right bank. The important large tributaries with substantial water discharge joining the Alaknanda river on left and right bank at 3.36 km and 4.7 km downstream of barrage axis are Ghrit Ganga and Khirao Ganga, respectively. Before confluencing with river Bhagirathi at Deoprayag, river Alaknanda is joined by major tributaries like rivers Birahi, Nandakini, Pindar (left bank tributaries), Balkila and Mandakini (right bank tributaries). The gradient of the river channel up to power house is 1:10. The gradient of entire course (31 km) of Saraswati river is 1:17. The tributaries joining the Saraswati river on its left bank have high gradient of the order of 1:3.5. The right bank tributaries have low gradient (1:16). The profile of the Rishi Ganga joining Alaknanda on its right bank has high gradient (1:5.8). In the catchment region of Alaknanda H.E. Project, very steep (50-70%) slope category covers only 2% of the entire catchment. Moderately steep slope (15-20%) category covers about 42% of the total catchment followed by steep slope (30-50%) category covering 29% (Fig. 4). Strongly sloping (8-15%) category has a substantial coverage of 16%. Moderately sloping (2-8%) and gently sloping categories together cover about 11% of the catchment. The gently sloping (0-2%) areas cover 5.3% of the catchment. The Digital Elevation Model (DEM) formed the basis for the generation of elevation-relief and aspect maps. As evident from the relief map major part (81.5%) of the catchment area lies in the elevational range 4,400 to 6,000 m of which 27.3% lies within 5,200-5,600 m. About 9.0% of the catchment lies within 4,000-4,400 m. Only small portion (0.6%) of the area lies above 6800 m.

  • 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).

Sci. & Humanities ISSN: 0975-9891 Vol. 14, (2019) 19-27 DOI: https://doi.org/10.51220/hjssh.v14i1.3 Impact of Dam on Channel Morphology of Alaknanda River in Srinagar Valley (Garhwal Himalaya) Sapna Semwal1 and D.D. Chauniyal2 1Department of Geography, DBS (PG) College, Dehara Dun 2Department of Geography, HNB Garhwal University Srinagar (Garhwal),Uttarakhand *Corresponding Author Email: [email protected] Received: 26.11.2019; Revised: 8.12.2019; Accepted: 28.12.2019 ©Society for Himalayan Action Research and Development Abstract: Rivers play a significant role in the human activities all over the world. Increasing demand of water for drinking & irrigation and hydroelectricity, numbers of impacts can be seen in the rivers environment. The present paper focuses on the impact of Supana Dam on the channel morphology of Alaknanda River in Srinagar valley Garhwal Himalaya. The field investigation approach has been adopted for the present study. The impact assessment has been carried out into three categories i.e. (i) Impact of dam on channel morphology, (ii) Impact of dam on human environment and (iii) Anthropogenic impact on channel Morphology. The results of the study show that after the construction of dam positive and negative impact have been assessed. Due to the blockage of water and sediment flow the entire riverine environment has been changed. Channel morphological features are well exposed for geomorphological study. Changing pattern of land and water relationship destroyed the previous ecosystem balance. Besides this, dam is supplying cheapest clean, efficient and reliable energy generated by hydro- electric power plant. Other impacts of dam are loss of fauna and flora, quality of drinking water supply and concentration of pollution in downstream.

(USA) Online ISSN: 2249-4626 & Print ISSN: 0975-5896 Diversity of Aquatic Insects and Function of Fluvial Ecosystem of Song River of Rajaji National Park, India By Nusrat Samweel & Tahir Nazir DIBNS Dehradun, India Abstract- Aquatic insect diversity of Rajaji National Park, India has been monitored for a period of twelve months. Some of the important hydrological attributes were also measured in continuity of one-month interval. Aquatic insects were sampled from two sites (S1 and S2) of the Song River of the Rajaji National Park. A significant difference in the density (t=2.86455, p<0.05) and diversity (t=5.23425, p<0.001) of aquatic insects was found due to differences in physicochemical setup of aquatic environment of these sites. It was also revealed that the nature, size and composition of bottom substrates have their significant impact on the diversity of benthic aquatic insects. The diversity of benthic aquatic insects ranged from 3.0270-4.4561 indicating the good quality of water. A high diversity (4.1085-4.4561) among aquatic insects was recorded in winter months when the water was almost clear with moderate temperature and water current, and high dissolved oxygen in the Song river of Rajaji National Park.
