Dohan river

The Dohan river, is a rain-fed river that originates at Mandholi village near Neem Ka Thana in Sikar district of Rajasthan and then disappears in Mahendragarh district in Haryana where it used to be a tributary of Sahibi River, which in turn is a still flowing tributary of Yamuna. Its canalised portion in one of its paleochannel in Haryana is called the "Outfall Drain No 8".

At Mandholi there is a small gomukh from where the river begins.

Several Ochre Coloured Pottery culture sites (also identified as late Harappan phase of Indus Valley civilisation culture) have been found along the banks of Krishnavati river, Sahibi river, Dohan river (tributary of Sahibi river) and Sota River (another tributary of sahibi river that merges with Sahibi at Behror in Alwar district).

Basin
The Dohan river originates from Aravalli Range near the village of Mandholi from the western slopes of the Dohan Protected Forest hills and flows towards north-east. The Krishnavati river, another independent River, flows north-east for about 42 km in Rajasthan and subsequently disappears in Haryana. The drainage pattern for both is dendritic.

Tributaries
These west to north-west flowing rivers originate from the western slopes of Aravalli range in Rajasthan, flow through semi-arid historical Shekhawati region, drain into southern Haryana.

Archaeological findings
Archaeological findings on the Sahibi River have confirmed habitations on its banks before the Harappan and pre-Mahabharata periods. Both handmade and wheel-made earthenware dated from 3309–2709 BCE and 2879–2384 BCE has been found on the banks of the Sahibi River at Jodhpura. INTACH-Rewari found pottery on the Sahibi riverbed at Hansaka in the Rewari district. A red stone statue of Vamana Dev was found in the Sahibi riverbed near Bawal in 2002; the statue is now displayed at the Shri Krishna Museum, Kurukshetra. Other artifacts discovered in the Sahibi River include arrowheads, fishhooks, appearheads, awls, and chisels.

Identification with Vedic rivers
