The Sankh River flows across Jharkhand, Chhattisgarh and Odisha states in India. The river flows for 240km (150miles) before it meets the Koel River in Odisha.
The river starts 1000m (3,000feet) above sea level in Lupungpat village in Gumla district in Jharkhand and flows 67.5km (41.9miles) in the state before entering Chhattisgarh. It runs a distance of about 50km (30miles) in Chhattisgarh and enters Jharkhand again to flow for another 78km (48miles). The river finally enters Odisha and travels another 45km (28miles) before merging with the Koel.[1] The South Koel enters Odisha and joins the Sankh River at Vedavyas near Rourkela from where it is called the Brahmani (see 22.2459°N 84.7838°W).[2]
The 60m (200feet) high Sadni Falls on the Sankh River at the edge of the Ranchi plateau is an example of scarp falls or knick line falls.[3]
