Its origin is Verinaag water source located in Jammu and Kashmir. Its total length is 730 kms and drainage area is 86,900 sq kms. Scientists are analysing various pros and cons of this project. The water quality should be safe and sound at the microbiological level and mere continuous supply is not enough. The Government of our country in various five years plans have constructed many dams at suitable locations so as to enable the country to achieve food and energy self- sufficiency for the people. The length of Gandak River is 425 kms and its catchment is 45,800 sq.
The arch curves towards the flow of water and the main water load is evenly distributed along the dam to the side walls. Sharma Water Availability and Quality in India:Water is available only for a few hours in most Indian cities and the quality is also not up to the mark. In urban areas, where the demand of 135 litres per capita daily lpcd is more than three times the rural demand of 40 lpcd, the scarcity assumes menacing proportions. Before merging into the Bay of Bengal, the river Vaitarni also joins it. Southern India consists largely of the Deccan Plateau, which is flanked by the Western Ghats running along the west coast and the smaller Eastern Ghats of the east coast. The all flow in to Bay of Bengal at various places along the Eastern coast of India.
Karnataka is located in the Deccan Peninsular region of India and covers an area of 191,791 square km. In the beginning, there are two branches of the Ganges namely — Bhagirathi and Alaknanda. At times the groundwater oozes out from the river banks and river bed into the river. А рart of the feeder canal will pass through Bangladesh territory for which India will have to reach an agreement with that country. Some 80 percent of its area experiences rains of 750 millimetres 30 in or more a year.
Rivers Of the total potential of nearly 1,900 billion cubic metres bcm in India, only about 700 bcm can be utilized. Detail estimate on global water availability; Indian Scenario: Surface water resources: Water resources including rivers, lakes or fresh water wetlands are known as surface water resources. Rao 1975 , the total quantity of water in our river systems is 1,644. Embankment dams depend on materials available near the site for its construction and hence they require less cost for construction. Nothing unusual showed up in the natural environment.
It has been seen that irrigated area in the World as about 18. Even dry areas like Rajasthan and Gujarat may have floods and wet areas like West Bengal may confront a situation of drought. Unbridled exploitation by farmers has led groundwater levels to plummet dangerously across large swathes of the countryside. In order to match rapidly increasing demand, India needs to make judicious use of its two sources of fresh water — surface water and groundwater. The height of Rakas Taal Lake is 4,630 metres above sea level. These originate in the North and generally flow in a West or South-West direction to eventually flow into Arabian Sea through Pakistan.
Near Kurnool in Andhra Pradesh River Tungabhadra joins it and in the south of Hyderabad river Musi joins it. Water woes are also because of insufficient or low pressure and erratic supplies. In spite of the availability of water from the river systems and tanks, Karnataka faces the serious issue of 67 percent of its land marked for irrigation falling under dry tracts. It contains impurities produced by sewage, industrial wastes, human and animal washings etc. There are lot of places, where the quality of groundwater is not good. Therefore, any appreciable use of static ground water on regular basis is not foreseen till the middle of the 21st century.
Ramganga: This is the main companion river joining Ganges from the left side. Suvanshiri, Dhanshiri, Maanas, Sankosh, Raidak, Tista, Diwang, Lohit, Deeshu, Kopili etc. Trans-basin transfer of water, also called interlinking of rivers, will enable utilisation of an additional 200 bcm of water. Its origin is from Kewanjhar plateau of Orissa. It has been found that 51 mha area is drought prone which constitute 16% of total geographical area. Rivers of southern India mostly originate from insular plateaus.
However, the idea survives in the popular mind and comes up whenever water scarcity is felt and conflicts such as Cauvery dispute become acute. The main river of this system is Ganges. The project aimed at reducing the impact of floods in the Ganga basin and supply water to central and eastern parts of the country which suffer from chronic problem of water shortage. These are rivers of arid regions, they carry relatively little flow, some of them flow to Arabian Sea through Gujrat while some are land-locked and their flow is lost through percolation and evaporation in the vast arid regions. It has chemical formula: H 2O.
