Answer: Indian National Trust for Art and Cultural Heritage
Notes: The Indian National Trust for Art and Cultural Heritage (INTACH) has traced the Sahibi River's flow. The river starts in Rajasthan and passes through Haryana and Delhi. It is a tributary of the Yamuna River and was formerly known as the Drishadvati River. Pollution and encroachment have greatly diminished its natural flow. Now, the river is divided into canals and nullahs, and it only flows during heavy rains in its catchment areas.
