Give a brief account of rivers of India which constitute the major water resources.

Water can be obtained from a variety of natural sources. The criteria to be satisfied by water sources are:

1. The quality of water must be acceptable

2. Quantity must be sufficient to meet the demand.

CLASSIFICATION OF WATER SOURCES

1. Above the surface : Rain

2. Surface water Reservoirs, rivers, streams, ponds, tanks and lakes.

3. Ground Water Shallow wells, deep wells and springs.

Rain

Rain is the most important source of water. It is the purest water free from pathogenic agents. It is clear, bright, sparkling and soft. Because it is soft, it has a corrosive action on lead pipes. Impurities: Suspended impurities like dust, soot, micro - organisms; gases like carbon dioxide, nitrogen and ammonia. These are picked up by rain water from the atmosphere.

Surface Water

The sources of surface water are i) Reservoirs ii) Rivers and streams iii) Tanks, ponds and lakes.

Reservoirs:

These are artificial lakes constructed by masonry or dams built across rivers. Water from reservoirs is clear, palatable, soft and free from pathogenic organisms. But it may be contami­nated by human habitations or animals.

Rivers:

Rivers satisfy water needs of several cities and villages. It contains impurities produced by sewage, industrial wastes, human and animal washings etc. So it is not suitable for dunking without treatment.

Tanks: They are large excavations in which water is stored. They form an important source of water in many of the Indian villages. They are contaminated by silt, colloidal matter, aquatic vegetation, washings of humans and cattle. Also the regular defecation around the edges may be drained into them by rain. Because of high degree of contamination, tank water is not suitable for drinking. Tanks can be improved by:

1. Raising the edges and fencing them.

2. By constructing an elevated platform from where water can be drawn.

3. Periodical removal of weeds.

4. Regular cleaning at the end of dry season.
