Question 4.
What is a khadin? Explain.
Answer:
Khadin is a method of water harvesting which was used by the Paliwal Brahmins of Jaisalmer during Medieval Period. This is an ideal method to ensure water for drinking and irrigation. In this method, the rainwater in hilly areas is collected along slopes; by making temporary or permanent check dam. Excess water is allowed to drain out so that another khadin can be fed with water. Khadin helps in recharge of underground aquifer, soil conservation and helps in maintaining moisture in the soil. This helps in getting better yield of rabi and kharif crops. This also helps in ensuring availability of water in beris which are built along its edges and in its catchment area.

Construction of baoris in Rajasthan was done at individual and social levels. Baoris can be found in all districts of Rajasthan,
Pond: Rainwater is collected in ponds which serve as a source of drinking water for humans and cattle. Most of the ponds are built near slopes. Construction of ponds has been associated with religious and social feelings. Hence, it becomes easier to protect and conserve them.
Lakes: Lakes are quite popular methods to conserve flowing water in this state. These lakes were built by local rulers, merchants and banjaras. Lakes provide drinking water and water for irrigation. These lakes fed the canals to provide irrigation for nearby areas. These lakes have facilitated the social and religious development of nearby areas and have also helped in sustaining life during drought and famine.
Nadi: This is a smaller form of pond which is in plenty in western Rajasthan. Nadi is used for rainwater harvesting in plains of desert. A nadi is generally 4 to 5 meter deep. If a nadi is shallower than this, then rainwater can be collected only for a short period because of the clay coming along with rainwater. The nadi is cleared of accumulated soil every year so that its depth can be maintained. Nadis have been important source of drinking water for rural population, cattle and wildlife in western Rajasthan.
Tanka: This is a traditional method of rainwater harvesting in western Rajasthan. This is 5 to 6 meter deep pit which is made in each house and field. Its top is covered with stones or other locally available material. Rainwater from rooftops and drains is collected in tanka. Its inner portion is covered with a layer of ash and gravel. This layer prevents seepage of water and erosion of the bottom. Tankas are being made under Jal Swavalamban Yojna and other schemes.
Johar: This is a popular method of rainwater harvesting in Shekhawati region and in Haryana. This is similar to tanka but its upper portion is larger than a tanka, is round and open. Rainwater is collected through drains in it. This serves as a good source of drinking water for people and cattle.
Beri or Small Well: These are made in western Rajasthan by digging a 5 to 6 meter deep pit on catchment land of pond and khadin. Its diameter is between 2 and 3 feet and walls are lined with stones. Stones on walls allow seepage of groundwater. This is used in summer when the rainwater dries up. This is called ‘beri’ in local language. Beris are in plenty in Barmer and Khadin. Khadin is a method of water harvesting which was used by the Paliwal Brahmins of Jaisalmer during Medieval Period. This is an ideal method to ensure water for drinking and irrigation. In this method, rainwater in hilly areas is collected along slopes; by making temporary or permanent check dam. Excess water is allowed to drain out so that another khadin can be fed with water. Khadin helps in recharge of underground aquifer, soil conservation helps in maintaining moisture in the soil. This helps in getting better yield of rabi and kharif crops. This also helps in ensuring availability of water in beris which are built along its edges and in its catchment area.
Question 2.
Explain the Indira Gandhi Canal Project in Rajasthan.
Answer:
Indira Gandhi Canal Project has been taken out form Harike Barrage which is situated on the confluence of Sutlej and Ravi rivers. This canal was built to ensure supply of drinking water, utilization of fallow land and to make human settlement along international border. This is the longest man-made canal not only in India but also in Asia. This canal is 649 km long; out of which 169 km is in Punjab, 14 km is in Haryana and rest is in Rajasthan. This canal supplies drinking water to 9 districts, 29 towns and 3461 villages in Rajasthan.

This canal supplies drinking water to 9 districts, 29 towns and 3461 villages in Rajasthan.
This canal was made in two phases which respectively include Rajasthan feeder canal and the main canal. Rajasthan feeder lies between the origin and Masitwali and is 204 km long. The main canal lies between Masitwali and the end point and is 445 km long. There are 9 branches towards the west, i.e. towards the international border. These branches are made along the slope. As the gradient is higher towards east, hence water is lifted up through lift canals and directed into the smaller branches. The total number of lift canals is 7. This canal would facilitate irrigation of 17.41 crore hectare of land. This project has now been extended up to Gadra Road of Barmer.
Question 3.

Question 4.
Explain any two major multipurpose dam projects of government of India.
Answer:
Damodar Valley Project: This is the first important project of independent India. This is a joint project of West Bengal and Jharkhand which was started in 1948 on Damodar River. Damodar was called the ‘Sorrow of Bengal’. This river was infamous for changing its course, erosion and flood. This river travels 290 km through Bihar along eastern parts of Chhotanagpur Plateau and 240 km through West Bengal; and finally flows in the Hooghly River. Barakar, Bokaro and Konar axe the tributaries of this river. About 18000 square km area is affected by erosion and flood caused by this river.

Barakar, Bokaro and Konar axe the tributaries of this river. About 18000 square km area is affected by erosion and flood caused by this river.
Hence, the Indian Government started Damodar Valley Corporation (DVC) on the lines of the American Tennessee (VTC) Valley Project. The purpose of this project is to improve the life of people of West Bengal and Jharkhand by facilitating economic development of this valley. The dams which are built in this project are Maithon Dam on Barakar River, Tilaiya Dam on Bal Pahari, Bokaro Dam on Bokaro River, Konar Dam on Konar River, Aghar Dam on Damodar River, Ath Dam on Bal Pahari and Durgapur Check Dam. Three power plants have been built at Bokaro, Chandrapura and Durgapur. A canal system over 2500 km has also been made under this project.
Hirakud Project: This is an ambitious project of Peninsular India and had been built on Mahanadi in Odisha. Mahanadi was called the ‘Sorrow of Odisha’. Mahanadi originates from the Bastar Hills in Chhattisgarh and passes through Odisha before falling in the Bay of Bengal. This river creates flood like situation in Odisha during monsoon but creates the problem of drought and famine during rest of the year. The Hirakud Dam was built with a cost of rupees 64 crore; 14 km uphill from Sambalpur. This is the longest dam in the world which is 4801 meter long and can store up to 810 crore cubic meter water. Additionally, two more dams have been built at Tikarpara and Naraj. This project was completed in two phases. The first phase involved construction of Hirakud Dam in Sambalpur district and by developing the Borgarh Canal System on its right, and the Sesan and Sambalpur Canal System on its left. The second phase involved construction of four power stations.

Water Resources Long Answer Type Questions
Question 1.
Write note on availability of water on earth and in India. Why do we need to ensure proper management of water resources?
Answer:
About 71% of earth’s surface is covered with water and rest 29% is covered with land. Out of total water on earth, 97% is in the form of saline water in oceans and seas and rest 3% is in the form of freshwater. Out of total freshwater on earth, 69% is in the form of ice (in icebergs and glaciers) and 30% is as underground water. Rest 1% water is used by humans for drinking of irrigation and economic activities. Total amount of potable water available in India is 1869 cubic meter, but only 1123 cubic meter water is utilized by us. Out of this amount, 690 cubic meter water is available as surface water, and 433 cubic meter is available as groundwater.
A major portion of rainwater goes to oceans through rivers and is thus wasted. Proper management of this water is necessary to tackle the problems of drought and famine which happen because of irregular monsoon. It is also important in order to meet the need of an ever growing population.
