Yamuna River in the context of "Brahmaputra River"

The Terai or Tarai is a lowland region in parts of southern Nepal and northern India that lies to the south of the outer foothills of the Himalayas, the Sivalik Hills and north of the Indo-Gangetic Plain. This region is characterised by tall grasslands, scrub savannah, sal forests and clay rich swamps. In North India, the Terai spreads from the Yamuna River eastward across Haryana, Uttarakhand, Uttar Pradesh, Bihar and West Bengal. The Terai is part of the Terai-Duar savanna and grasslands ecoregion.Nepal's Terai stretches over 33,998.8 km (13,127.0 sq mi), about 23.1% of Nepal's land area, and lies at an elevation of between 67 and 300 m (220 and 984 ft). The region comprises more than 50 wetlands. North of the Terai rises the Bhabar, a narrow but continuous belt of forest about 8–12 km (5.0–7.5 mi) wide.

Yamunotri, also Jamnotri, is the source of the Yamuna River and the seat of the Goddess Yamuna in Hinduism. It is situated at an altitude of 3,293 metres (10,804 ft) in the Garhwal Himalayas and located approximately 150 kilometres (93 mi) North of Uttarkashi, the headquarters of the Uttarkashi district in the Garhwal Division of Uttarakhand, India. It is one of the four sites in India's Chota Char Dham pilgrimage. The sacred shrine of Yamunotri, source of the river Yamuna, is the westernmost shrine in the Garhwal Himalayas, perched atop a flank of the Bandarpunch mountain. The chief attraction at Yamunotri is the temple devoted to the Goddess Yamuna and the holy thermal springs at Janki Chatti which is 7 km away.

The actual source, a frozen lake of ice and glacier (Champasar Glacier) located on the Kalind Mountain at a height of 4,421 m above sea level, about 1 km further up, is not frequented generally as it is not accessible; hence the shrine has been located on the foot of the hill. The approach is extremely difficult and pilgrims therefore offer puja at the temple itself.

Sone River, also spelt Son River, is a perennial river located in central India. It originates near Amarkantak Hill in Pendra (Gaurela-Pendra-Marwahi district), Chhattisgarh and finally merges with the Ganges river near Maner in Patna, Bihar. The Sone River is the second-largest southern tributary of the Ganges after the Yamuna River. India's oldest river bridge Koilwar Bridge over the Sone River connects Arrah with Patna. Sone river is famous for its sand across country. Multiple dams and hydro-electric projects run on its course towards the Ganges.The river is also mentioned in Valmiki Ramayans's Balkand where Ram. Laxman along with Vishvamitra is crossing the river to further go north towards Ganga.

Johilla River is a river in Amarkantak, a pilgrim town in Madhya Pradesh, India. It is a tributary of the Son river, which is a perennial river located in Central India and is the second-largest southern tributary of the Ganges after the Yamuna River.
