Chapter 3 Water Resources Case Study Questions Class 10 Social Science
1. Read the source given below and answer the following questions:
Today, dams are built not just for irrigation but for electricity generation, water supply for domestic and industrial uses, flood control, recreation, inland navigation and fish breeding. Hence, dams are now referred to as multi-purpose projects where the many uses of the impounded water are integrated with one another. For example, in the Sutluj-Beas river basin, the Bhakra – Nangal project water is being used both for hydel power production and irrigation. Similarly, the Hirakud project in the Mahanadi basin integrates conservation of water with flood control. Multi-purpose projects, launched after Independence with their integrated water resources management approach, were thought of as the vehicle that would lead the nation to development and progress, overcoming the handicap of its colonial past. Jawaharlal Nehru proudly proclaimed the dams as the ‘temples of modern India’; the reason being that it would integrate development of agriculture and the village economy with rapid industrialisation and growth of the urban economy.

2. Read the source given below and answer the following questions:
Many thought that given the disadvantages and rising resistance against the multipurpose projects, water harvesting system was a viable alternative, both socio-economically and environmentally. In ancient India, along with the sophisticated hydraulic structures, there existed an extraordinary tradition of water-harvesting system. People had in-depth knowledge of rainfall regimes and soil types and developed wide ranging techniques to harvest rainwater, groundwater, river water and flood water in keeping with the local ecological conditions and their water needs. In hill and mountainous regions, people built diversion channels like the ‘guls’ or ‘kuls’ of the Western Himalayas for agriculture. ‘Rooftop rainwater harvesting’ was commonly practised to store drinking water, particularly in Rajasthan. In the flood plains of Bengal, people developed inundation channels to irrigate their fields. In arid and semi-arid regions, agricultural fields were converted into rain fed storage structures that allowed the water to stand and moisten the soil like the ‘khadins’ in Jaisalmer and ‘Johads’ in other parts of Rajasthan. In the semi-arid and arid regions of Rajasthan, particularly in Bikaner, Phalodi and Barmer, almost all the houses traditionally had underground tanks or tankas for storing drinking water.
Answer the following MCQs by choosing the most appropriate option.
(i) Agricultural fields which are used as rainfed storage structures are called:
(a) Kuls
(b) Khadins/Johads
(c) Recharge pits
(d) None of the above
Answer
A
(ii) In which of the following regions, people built ‘Guls’ and ‘Kuls’ for irrigation?
(a) Northern Plains
(b) Western Himalayas
(c) Coastal areas
(d) None of these
Answer
B
(iii) The diversion channels seen in the Western Himalayas are called:
(a) Guls or Kuls
(b) Khadins
(c) Johads
(d) Recharge pits
Answer
A
(iv) Underground tanks seen in Rajasthan to store rainwater for drinking is called:
(a) Tankas
(b) Khadis
(c) Ponds
(d) Kuls
Answer
A
