GODAVARI BASIN DETAILS (http://www.sakti.in/godavaribasin/basindetails.htm)
Water is one of the five elements. No water, no life. Water is the source of live. There are several rivers that make India
greeny. Ganges; Yamuna, Saraswathi, Sindhu, Narmada, Godavari, Kaveri and Krishna are the symbols of our
civilization. River water is a national asset. River is gift of nature; therefore no body has monopoly on it. The Godavari is
the biggest river in South India. It originates near Triambak in Nashik district of Maharashtra. The river runs from western
to south India. The river flows eastwardly across the Deccan Plateau among the states of Maharasthra, Chattisgarh and
Andhra Pradesh, then crossing the latter state and turning to flow in a southeast direction via Polavaram until it empties
into the Bay of Bengal near Rajamundry.
It flows 1465 km, 694 km in Maharasthra, and 767 km in Andhra Pradesh. It flows 653 km in Telangana and 114 km in
Andhra area.
Its tributies includes Manjira, Pranahita, Sabari, Poorna, Maneru, Penganga, and Wainganga Godavari tributaries are
spread over Maharasthra, Chattisgarh, Orissa, Karnataka and Andhra Pradesh. Therefore, the rivers are recognized as
Inter-state River.

Basin characteristics
The Godavari basin receives major part of its rainfall during the Southwest monsoon period. The other rainy seasons are not so
well defined and well spread as the South-West monsoon season. They contribute about 16% of the total annual rainfall in the
Godavari basin. The annual rainfall of Godavari basin varies from 3000 mm to 600 mm. The Godavari basin has a tropical
climate. The mean annual surface temperature in the Western Ghat area is about 24oC, and it increases gradually towards the east
and attains a maximum of 29.4oC on the East Coast. During January the mean daily minimum temperature increases from West to
East from 15oC on the Western Ghats to about 18oC on the East Coast. The mean maximum daily temperature generally exceeds
30oC in the western part of the Godavari basin and it is only slightly less than 30oC in the Eastern part.
The population of the basin, based on 2001 census was 60.57 million out of which about 75% live in rural and remaining 25% in
urban areas. The density of population is around 194 persons per km2. Nearly 40% of work force is engaged in cultivation, 30% as
agriculture labour and balance 30% in mining, manufacturing etc.
Except for the hills forming the watershed around the basin, the entire drainage basin of the river Godavari comprises of
undulating country, a series of ridges and valleys interspersed with low hill ranges. Large flat areas which are characteristic of the
Indo-Gangetic plains are scarce except in the delta. The Sahyadri ranges of Western Ghats form the Western edge of the basin.
The interior of the basin is a plateau divided into a series of valleys sloping generally towards East. The Eastern Ghats, which
form the Eastern boundary, are not so well defined as the Sahyadri range on the West. The Northern boundary of the basin
comprises of tablelands with varying elevation. Large stretches of plains interspersed by hill ranges lie to the South.
