Answer 2

Son River is largest of southern tributaries of Ganga that originates near Amarkantak in Madhya Pradesh near the source of Narmada River, and flows north-northwest through Madhya Pradesh before turning sharply eastward where it encounters the southwest-northeast-running Kaimur Range.

The Son parallels the Kaimur hills, flowing east-northeast through Uttar Pradesh, Jharkhand and Bihar states to join the Ganga just above Patna. Geologically, the lower valley of the Son is an extension of the Narmada Valley, and the Kaimur Range an extension of the Vindhya Range.Chief tributaries of Son river are Rihand and the North Koel. The Son has a steep gradient (35–55 cm per km) with quick run-off and ephemeral regimes, becoming a roaring river with the rain-waters in the catchment area but turning quickly into a fordable stream.The Rihand River is a tributary of the Son River and flows through the Indian states of Chhattisgarh and Uttar Pradesh. It rises in Chhattisgarh at Matiranga hills and there is a Rihand Dam that was constructed at Pipri in Sonbhadra district of Mirzapur division in 1962 for hydropower generation. The reservoir of this dam is called Govind Ballabh Pant Sagar. Rihand meets Son at Sonbhadra of Uttar Pradesh.
