Hint: When a water –bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out with a hand pump or tube well.
Complete step by step answer:
A tube well is a type of water well in which a long, \[100 - 200\] millimeter wide and stainless steel tube is bored into an underground aquifer. The lower end is fitted with a strainer and a pump lifts water for irrigation. The required depth of the well depends on the depth of the upper surface of water.
Boreholes and tube wells are important adaptation technology measures for providing a domestic water supply during the times of water shortages and drought.
Advantages of tube well irrigation:
(i) Ground water easily available
(ii) More reliable during periods of drought when surface water vanishes.
(iii) Suitable for small holdings.
Hence, the correct option is B and D.
Note: A small reservoir of water is made at the outlet of the tube well. This reservoir is used for different usage of water by the local population. One disadvantage of using tube wells, it can be dug only in those areas where the underground water table is high.
