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 bringing enormous amounts of water in the plains of Punjab, Rajasthan and north Gujarat.
