Question

How is the usable water distributed over India

Answer 1

Answer:

Water Availability and Quality in India:Water is available only for a few hours in most Indian cities and the quality is also not up to the mark.Water woes are also because of insufficient or low pressure and erratic supplies.The rural population suffers from low water quality but the urban and semi- urban areas are most prone to water shortage.The water quality should be safe and sound at the microbiological level and mere continuous supply is not enough. Another aspect is the water wastage in terms of leakages and illegal connections.

Answer:

Water resources in India includes information on precipitation, surface and groundwater storage and hydropower potential. India experiences an average precipitation of 1,170 millimetres (46 in) per year, or about 4,000 cubic kilometres (960 cu mi) of rains annually or about 1,720 cubic metres (61,000 cu ft) of fresh water per person every year.[1] India accounts for 18% of the world population and about 4% of the world’s water resources. One of the solutions to solve the country’s water woes is to create Indian Rivers Inter-link.c[2] Some 80 percent of its area experiences rains of 750 millimetres (30 in) or more a year. However, this rain is not uniform in time or geography. Most of the rains occur during its monsoon seasons (June to September), with the north east and north receiving far more rains than India's west and south. Other than rains, the melting of snow over the Himalayas after winter season feeds the northern rivers to varying degrees. The southern rivers, however experience more flow variability over the year. For the Himalayan basin, this leads to flooding in some months and water scarcity in others. Despite extensive river system, safe clean drinking water as well as irrigation water supplies for sustainable agriculture are in shortage across India, in part because it has, as yet, harnessed a small fraction of its available and recoverable surface water resource. India harnessed 761 cubic kilometres (183 cu mi) (20 percent) of its water resources in 2010, part of which came from unsustainable use of groundwater.[3] Of the water it withdrew from its rivers and groundwater wells, India dedicated about 688 cubic kilometres (165 cu mi) to irrigation, 56 cubic kilometres (13 cu mi) to municipal and drinking water applications and 17 cubic kilometres (4.1 cu mi) to industry.[1]
