Chautang
The Chautang, originating in Siwalik Hills, is a tributary of Sarsuti river which in turn is tributary of Ghaggar river in of Haryana state of India.Origin and route
The Chautang river is a seasonal river in the state of Haryana, India. It is theorized by some to be a remnant of the ancient river Drsadvati and joins the Ghaggar-Hakra River east of Suratgarh in Rajasthan. Sime suggest, however, that the Drsadvati river is actually the Arghandab River in Afghanistan. According to McIntosh, this river was one of the main contributors to this river system until the Yamuna changed its course. However, according to Giosan, the Chautang is a rain-fed river, and the Yamuna changed its course towards east some 50,000 to 10,000 years ago, and didn't pour any water into it for the last 10,000 years. Hansi Branch of Western Yamuna Canal is palaeochannel of this river.
