Many rivers in India are shared resources, flowing through or between more than one province and more than one country. The combined effect of climatic stochasticity, rapid population growth and inefficient water infrastructure is increasing stress on river basin ecosystems.
Geological records point out to a period of aridity 10,000 years ago, at the end stage of Pleistocene glaciation, which gradually changed to a wet phase. Copious rainfall in the Himalayan region gave rise to innumerable rivers, mainly Saraswati river along with six other rivers which flowed down in cascades …
