River Saraswati is believed to have flown through the Thar Desert, as reconstructed by several experts based on critical data gathered by them. A careful observation of the channel shows that in most of the places these are fault-controlled. Studies of palaeochannels in many parts of the world proved successful in identifying high-yielding freshwater zones. Presence of fault system accelerates the recharge process and down-flow of water gets maximized through fault planes during the wet period.
