Vindhya in the context of "Central India"

Kishkindha (Sanskrit: किष्किन्धा, IAST: Kiṣkindhā) is a kingdom mentioned in Ramayana. It is ruled by King Sugriva, the younger brother of Vali, in the Sanskrit epic Ramayana. According to the Hindu epic this was the kingdom that Sugriva ruled with the assistance of his counsellor, Hanuman. Kishkindha is identified with the present location of Hampi, the erstwhile royal capital of Vijayanagara Empire.

During the Treta Yuga, the whole region was within the dense Dandaka Forest which was founded by King Danda, son of Ikshvaku, and descendant of Vaivasvata Manu in the Satya Yuga, which extended from the Vindhya range to the South Indian peninsula. Thus, this kingdom was considered that of the vanaras. During the Dvapara Yuga, the Pandava Sahadeva is stated to have visited this kingdom in the epic Mahabharata during his southern military campaign to collect tribute for Yudhishthira's Rajasuya sacrifice.

The Narmada River (IPA: [nəɾməd̪aː]), previously also known as the Narbada or anglicised as Nerbudda, is the 5th longest river in India and overall the longest west-flowing river in the country. It is also the largest flowing river in the state of Madhya Pradesh. This river flows through the states of Madhya Pradesh and Gujarat in India and is known as their lifeline due to its contribution to the two states in many ways. The Narmada River rises from the Amarkantak Plateau in the Anuppur district in Madhya Pradesh. It forms the traditional boundary between North and South India and flows westwards for 1,312 km (815.2 mi) before draining through the Gulf of Khambhat into the Arabian Sea, 30 km (18.6 mi) west of Bharuch city of Gujarat.

It is one of only two major rivers in peninsular India that runs from east to west (longest west flowing river), along with the Tapti River. It is one of the rivers in India that flows in a rift valley, bordered by the Satpura and Vindhya ranges. As a rift valley river, the Narmada does not form a delta; Rift valley rivers form estuaries. Other rivers which flow through the rift valley include the Damodar River in Chota Nagpur Plateau and Tapti. The Tapti River and Mahi River also flow through rift valleys, but between different ranges. It flows through the states of Madhya Pradesh (1,077 km (669.2 mi)), and Maharashtra, (74 km (46.0 mi)), (39 km (24.2 mi)) (actually along the border between Madhya Pradesh and Maharashtra (39 km (24.2 mi)) and then the border between Maharashtra and Gujarat (74 km (46.0 mi)) and in Gujarat (161 km (100.0 mi)).

The Ganges Basin is a major part of the Ganges-Brahmaputra-Meghna (GBM) basin draining 1,999,000 square kilometres in Tibet, Nepal, India and Bangladesh. To the north, the Himalaya or lower parallel ranges beyond form the Ganges-Brahmaputra divide. On the west the Ganges Basin borders the Indus basin and then the Aravalli ridge. Southern limits are the Vindhyas and Chota Nagpur Plateau. On the east the Ganges merges with the Brahmaputra through a complex system of common distributaries into the Bay of Bengal. Its catchment lies in the states of Uttar Pradesh (294,364 km), Madhya Pradesh (198,962 km), Bihar (143,961 km), Rajasthan (112,490 km), West Bengal (71,485 km), Haryana (34,341 km), Himachal Pradesh (4,317 km), Delhi, Arunachal Pradesh (1,484 km), the whole of Bangladesh, Nepal and Bhutan. Several tributaries rise inside Tibet before flowing south through Nepal. The basin has a population of more than 500 million, making it the most populated river basin in the world.
