1.Why are some rivers perennial?
2. What do rivers bring down with them?
3. Why do the rivers of the Deccan Plateau empty themselves into the Bay of
Bengal?
4. What measures has the government undertaken to provide water in areas with
a water problem?
5. Name two rivers that empty themselves into the Arabian Sea.
Answers
1. The name Perennial is derived from a Latin word ‘perennis’, which means lasting throughout the year. As they flow continuously throughout the year irrespective of seasons, they are also called permanent rivers.
Mostly they originate from the mountain and the water is fed by melting of glaciers. These rivers are mostly found in North India due to the presence of the great mountain range Himalaya that is fully covered with snow. Whereas in south India there is no mountain with snow so the south Indian rivers are non-perennial rivers. These streams are of vital importance in agriculture because they provide water throughout the year. For e.g.,Ganga is the best example of a perennial river. These rivers get water by rain in rainy season, melting of ice in summer and by snow in the winter season.
2. One of the key elements that river carries is silt or sediment (although there is a slight difference between the two, we will use it interchangeably here). The rivers carry silt from various points in their journey from the hills, to the deltas where most major rivers meet the sea.
3. Most of the Peninsular Rivers drain into the Bay of Bengal because: The Eastern Ghats are lower than the Western Ghats and moreover the Eastern Ghats are discontinuous providing the rivers an easy passage to the Bay of Bengal. The Deccan Plateau slopes towards the east.
4. Types of common works undertaken under these programmes/ schemes are water conservation and management, water harvesting, soil and moisture conservation, groundwater recharge, flood protection, land development, Command Area Development & Watershed Management.
5. The two prominent rivers which drain into the Arabian Sea are Narmada and Tapi.
Hope it helps, mate!
