  • Estimation of Paleo-Discharge of the Lost Saraswati River, North West India
    EGU2020-21212 https://doi.org/10.5194/egusphere-egu2020-21212 EGU General Assembly 2020 © Author(s) 2021. This work is distributed under the Creative Commons Attribution 4.0 License. Estimation of paleo-discharge of the lost Saraswati River, north west India Zafar Beg, Kumar Gaurav, and Sampat Kumar Tandon Indian Institute of Science Education and Research Bhopal, Earth and Environment Sciences, India ([email protected], [email protected], [email protected] ) The lost Saraswati has been described as a large perennial river which was 'lost' in the desert towards the end of the 'Indus-Saraswati civilisation'. It has been suggested that this paleo river flowed in the Sutlej-Yamuna interfluve, parallel to the present-day Indus River. Today, in this interfluve an ephemeral river- the Ghaggar flows along the abandoned course of the ‘lost’ Saraswati River. We examine the hypothesis given by Yashpal et al. (1980) that two Himalayan-fed rivers Sutlej and Yamuna were the tributaries of the lost Saraswati River, and constituted the bulk of its paleo-discharge. Subsequently, the recognition of the occurrence of thick fluvial sand bodies in the subsurface and the presence of a large number of Harappan sites in the interfluve region have been used to suggest that the Saraswati River was a large perennial river. Further, the wider course of about 4-7 km recognised from satellite imagery of Ghaggar-Hakra belt in between Suratgarh and Anupgarh in the Thar strengthens this hypothesis. In this study, we have developed a methodology to estimate the paleo-discharge and paleo- width of the lost Saraswati River.

Sustainable management of the nearly 3 million springs in the region requires a framework to identify the springs most vulnerable to change agents which can be biophysical or socio-economic, internal or external. In this study, we conceptualize vulnerability in the Indian Himalayan springs. By way of a systematic review of the published literature and synthesis of research findings, a scheme of identifying and quantifying these change agents (stressors) is presented. The stressors are then causally linked to the characteristics of the springs using indicators, and the resulting impact and responses are discussed. These components, viz., stressors, state, impact, and response, and the linkages are used in the conceptual framework to assess the vulnerability of springs. A case study adopting the proposed conceptual model is discussed Citation: Daniel, D.; Anandhi, A.; for Mathamali spring in the Western Himalayas. The conceptual model encourages quantification Sen, S.

  • Current Condition of the Yamuna River - an Overview of Flow, Pollution Load and Human Use
    Current condition of the Yamuna River - an overview of flow, pollution load and human use Deepshikha Sharma and Arun Kansal, TERI University Introduction Yamuna is the sub-basin of the Ganga river system. Out of the total catchment’s area of 861404 sq km of the Ganga basin, the Yamuna River and its catchment together contribute to a total of 345848 sq. km area which 40.14% of total Ganga River Basin (CPCB, 1980-81; CPCB, 1982-83). It is a large basin covering seven Indian states. The river water is used for both abstractive and in stream uses like irrigation, domestic water supply, industrial etc. It has been subjected to over exploitation, both in quantity and quality. Given that a large population is dependent on the river, it is of significance to preserve its water quality. The river is polluted by both point and non-point sources, where National Capital Territory (NCT) – Delhi is the major contributor, followed by Agra and Mathura. Approximately, 85% of the total pollution is from domestic source. The condition deteriorates further due to significant water abstraction which reduces the dilution capacity of the river. The stretch between Wazirabad barrage and Chambal river confluence is critically polluted and 22km of Delhi stretch is the maximum polluted amongst all. In order to restore the quality of river, the Government of India (GoI) initiated the Yamuna Action Plan (YAP) in the1993and later YAPII in the year 2004 (CPCB, 2006-07). Yamuna river basin River Yamuna (Figure 1) is the largest tributary of the River Ganga. The main stream of the river Yamuna originates from the Yamunotri glacier near Bandar Punch (38o 59' N 78o 27' E) in the Mussourie range of the lower Himalayas at an elevation of about 6320 meter above mean sea level in the district Uttarkashi (Uttranchal).

  • Ganga As Perceived by Some Ganga Lovers Mother Ganga's Rights Are Our Rights
    Ganga as Perceived by Some Ganga Lovers Mother Ganga’s Rights Are Our Rights Pujya Swami Chidanand Saraswati Nearly 500 million people depend every day on the Ganga and Her tributaries for life itself. Like the most loving of mothers, She has served us, nourished us and enabled us to grow as a people, without hesitation, without discrimination, without vacation for millennia. Regardless of what we have done to Her, the Ganga continues in Her steady fl ow, providing the waters that offer nourishment, livelihoods, faith and hope: the waters that represents the very life-blood of our nation. If one may think of the planet Earth as a body, its trees would be its lungs, its rivers would be its veins, and the Ganga would be its very soul. For pilgrims, Her course is a lure: From Gaumukh, where she emerges like a beacon of hope from icy glaciers, to the Prayag of Allahabad, where Mother Ganga stretches out Her glorious hands to become one with the Yamuna and Saraswati Rivers, to Ganga Sagar, where She fi nally merges with the ocean in a tender embrace. As all oceans unite together, Ganga’s reach stretches far beyond national borders. All are Her children. For perhaps a billion people, Mother Ganga is a living goddess who can elevate the soul to blissful union with the Divine. She provides benediction for infants, hope for worshipful adults, and the promise of liberation for the dying and deceased. Every year, millions come to bathe in Ganga’s waters as a holy act of worship: closing their eyes in deep prayer as they reverently enter the waters equated with Divinity itself.

  • Yamuna River Water Pollution-A Review Pankaj
    ISSN XXXX XXXX © 2019 IJESC Research Article Volume 9 Issue No. 5 Yamuna River Water Pollution-A Review Pankaj. V. Sharma1, Monika Bhadauriya2 Department of Environmental Science Government Science College, Gujarat University, Ahmedabad, Gujarat, India Abstract: This paper reviews the impact of industrial pollution on Yamuna River based on studies over the past few years. It Engenders from Yamunotri glaciers in the lower Himalayas at an elevation of approximately 6387 meters. River can be divided into five segments on the foundation of hydrological and ecological situation. The river is contaminated by both point and non-point sources, where National Capital Territory (NCT) – Delhi is the main Helper, followed by Agra and Mathura. The Delhi segment is the most polluted as the river gets severely affected by the impediments of industrialization, urbanization and agricultural advances. In addition to municipal sewage, a large number of diverse industries like pulp and paper, steel plants, chemicals, rubber, sugar, tannery, glass, engineering, plastics, and food processing directly Release their wastes into it. There 22 industrial units in Haryana, 42 units in Delhi and 17 units in Uttar Pradesh which were found to be directly discharging and polluting the Yamuna River. This is due to discharge of environmental pollutants or effluents into water bodies without treatment. Water pollution affects the whole biosphere, including not only the individual species but also their natural biological denomination. It results in the death of much of the aquatic life inhabitant inside the defective water body. Pollution levels in the Yamuna River have arise. Average Biochemical Oxygen Demand (BOD) and Dissolved Oxygen (DO) levels at this point are 1.2 mg/l and 11.7 mg/l respectively.

  • PPT on Yamuna
    PPT ON REJUVENATION OF RIVER YAMUNA THE IMPACT OF THE YAMUNA ON LIFE AND LIVING IN DELHI The Yamuna is the most important tributary of the Ganga and its source is the Yamunotri glacier. Important pilgrimage centers like Yamunotri, Paonta Sahib, Mathura, Vrindavan, Bateshwar & Allahabad ( now Prayagraj) are located on the banks of the river. In Indian mythology Yamuna is referred as the daughter of the Sun and sister of Yama. The baby Krishna is believed to have been born on the bank of this river and is said to have freed Yamuna from “Kalia Nag.” The Yamuna’s basin is one of the most fertile and high grain yielding river basins in the country and a boon for agriculture. Apart from the Capital city Delhi, many large urban hubs and cities like Yamuna Nagar,Panipat, Sonepat, Gautam Budh Nagar, Faridabad, Mathura, Agra and Etawah are situated on the river’s banks.The challenge lies in harnessing the river to boost environmentally safe and sustainable activities. RIVER YAMUNA’S IMPORTANCE FOR LIFE AND LIVELIHOODS ➢ Yamuna as a Life Line The river water is used for drinking and agriculture by the basin states of Uttarakhand,* Haryana, Uttar Pradesh, Delhi & Rajasthan. The share of each state has been decided by a Memorandum of Understanding signed by all the states in 1994 and is being regulated by the Upper River Yamuna Board (MoWR, RD&GR.) ➢ Ground water recharge: The river helps replenish the water table by recharging it with flood water and performing important ecological functions. It sustains aquatic biodiversity and brings with it nutrient rich alluvial sedimentation full of minerals and organic matter, during the monsoon months.

    Course: Water Management in Horticultural Crops 2(1+1), 1st year, 2nd semester WATER RESOURCES IN INDIA Dr. Vikas Gupta, College of Horticulture, Rehli Importance Of Water In Plants And Soil: (1) All living things need water to stay alive and plants are also living things. (2) Plants need much more water than many other living things because plants use much more water to maintain their turgor, which is water pressure inside the cells that make up the plant's skeleton. (3) Water is used for transpiration carrier of nutrients from the soil to green plant tissues. (4) In photosynthesis process plant uses light, water and carbon dioxide to create energy and food. Plants can synthesis food through photosynthesis only in the presence of water in their system. (5) Without enough water in the cells, the plants droop, so water helps a plant stand. (6) Water carries the dissolved sugar and other nutrients throughout the plant and its cells. (7) Water saves the plant from dehydrating. It is also used to transport the nutrients. (8) Soil water is the medium from which all plant nutrients are assimilated by plants. (9) Water plays vital role in the different biological, physical and chemical reactions in the plants as well as soil. (10) Water is also essential for the life of macro and micro fauna of the soil. (11) All the anabolic and catabolic activities of plants only occur in the medium of water. (12) Agronomic activities like land preparation, ploughing, leveling, sowing, hoeing etc. conveniently possible only under sufficient soil moisture condition.
