Ghaggar-Hakra River: An intermittent river in India and Pakistan that flows only during the monsoon season. While it is often identified with the Sarasvati River, this is not a consensus view. The Hakra is the dried-out channel of a river in Pakistan that is the continuation of the Ghaggar River in India. Several times, but not continuously, it carried the water of the Sutlej during the Bronze Age period  Many settlements of the Indus Valley Civilisation have been found along the Ghaggar and Hakra rivers.
Saraswati River: Also known as Sarasvati River. This river was one of the major rivers of Ancient India which no longer exists.
