Godavari Delta
The river has been revered in Hindu scriptures for many millennia and continues to harbour and nourish a rich cultural heritage. In the past few decades, the river has been barricaded by several barrages and dams, keeping a head of water (depth) which lowers evaporation. Its broad river delta houses 729 persons/km – nearly twice the Indian average population density and has a substantial risk of flooding, which in lower parts would be exacerbated if the global sea level were to rise.
Course
The Godavari originates in the Western Ghats of central India near Nashik in Maharashtra, 80 km (50 mi) from the Arabian Sea. It flows for 1,465 km (910 mi), first eastwards across the Deccan Plateau then turns southeast, entering the Eluru district and Alluri Sitharama Raju district of Andhra Pradesh, until it splits into two distributaries that widen into a large river delta at Dhavaleshwaram Barrage in Rajamahendravaram and then flows into the Bay of Bengal.
The Godavari River has a coverage area of 312,812 km (120,777 sq mi), which is nearly one-tenth of the area of India and is equivalent to the area of the United Kingdom and Republic of Ireland put together. The river basin is considered to be divided into 3 sections:
- Upper (source to the confluence with Manjira),
- Middle (between confluence of Manjira and Pranhita) and
- Lower (Pranhita confluence to mouth).
These put together account for 24.2% of the total basin area. The rivers annual average water inflows are nearly 110 billion cubic metres. Nearly 50% of the water availability is being harnessed. The water allocation from the river among the riparian states are governed by the Godavari Water Disputes Tribunal. The river has highest flood flows in India and experienced recorded flood of 3.6 million cusecs in the year 1986 and annual flood of 1.0 million cusecs is normal.
Within Maharashtra
The river originates in Maharashtra state and has an extensive course. The upper basin (origin to its confluence with Manjira) of which lies entirely within the state, cumulatively draining an area as large as 152,199 km (58,764 sq mi) – about half the area of Maharashtra. Within Nashik district, the river assumes a north-easterly course until it flows into the Gangapur Reservoir created by a dam of the same name. The reservoir along with the Kashypi Dam provides potable water to Nashik, one of the largest cities located on its banks. The river as it emerges through the dam, some 8 km (5.0 mi) upstream from Nashik, flows on a rocky bed undulated by a series of chasms and rocky ledges, resulting in the formation of two significant waterfalls – the Gangapur and the Someshwar waterfalls. The latter, located at Someshwar is more popularly known as the Dudhsagar Waterfall. About 10 km (6.2 mi) east of Gangapur the river passes the town of Nashik where it collects its effluents in the form of the river Nasardi on its right bank.
About 0.5 km (0.31 mi) south of Nashik, the river bends sharply to the east, washing the base of a high cliff formerly the site of a Mughal fort, but which is now being eroded away by the action of floods. About 25 km (16 mi) below Nashik is the confluence of the Godavari and one of its tributaries, the Darna. The stream occupies, for nine months in the year, a small space in a wide and gravelly bed, the greyish banks being 4 to 6 m (13 to 20 ft) high, topped with a deep layer of black soil. A few kilometres after its meeting with the Darna, the Godavari swerves to the north-east, before the Banganga, from the north-west, meets it on the left. The course of the main stream then tends more decidedly south. At Nandur-Madhmeshwar, the Kadva, a second large affluent, brings considerable increase to the waters of the Godavari. The river begins its southeasterly course characteristic of rivers of the Deccan Plateau. The river exits the Niphad Taluka of Nashik and enters the Kopargaon taluka, Ahmednagar District. Within Ahmednagar District the river quickly completes its short course, flowing alongside the town of Kopargaon and reaching Puntamba. Beyond this, the river serves as a natural boundary between the following districts:
- Ahmednagar and Aurangabad: Along the boundary here, it receives its first major tributary the Pravara River, draining the former district. The confluence is located at Pravarasangam. By virtue of a sub-tributary of Pravara – Mandohol, which originates in Pune District – the basin impinges the Pune district. The river at Paithan has been impounded by the Jayakwadi Dam forming the NathSagar Reservoir. Kalsubai located in Godavari basin, is the highest peak in Maharashtra.
- Beed and Jalna
- Beed and Parbhani: Located along here is its merger with Sindphana, an important tributary which drains a considerably large area within Beed. The sub-tributary river Bindusara forms a landmark at Beed.
The river beyond, near the village Sonpeth, flows into Parbhani. In Parbhani district, the river flows through Gangakhed taluka. As mentioned above, the Godavari is also called Dakshinganga so the city is called as Gangakhed (meaning a village on the bank of Ganga). As per Hindu rituals this place is considered quite important for after death peace to flow ashes into the river.
Its course is relatively non-significant except for receiving two smaller streams – Indrayani and Masuli – merging at its left and right banks, respectively. Within the last taluka of the district Parbhani, Purna, the river drains a major tributary of the same name: Purna.
It then exits into the neighbouring district of Nanded where 10 km (6.2 mi) before reaching the town Nanded, it is impounded by the Vishnupuri Dam and thus with it, bringing Asia's largest lift irrigation projects to life. A little downstream from Nanded, the river receives Asna, a small stream, on its left bank. It then runs into the controversial Babli project soon ends its course within Maharashtra, albeit temporarily, at its merger with a major tributary – Manjira.
The river after flowing into Telangana, re-emerges to run as a state boundary separating the Mancherial, Telangana from Gadchiroli, Maharashtra. At the state border, it runs between Sironcha and Somnoor Sangam receiving one tributary at each of those nodal points – the Pranhita and subsequently the Indravati.
Within Telangana
Godavari enters into Telangana in Nizamabad district at Kandakurthy where Manjira, Haridra rivers joins Godavari and forms Triveni Sangamam. The river flows along the border between Nirmal and Mancherial districts in the north and Nizamabad, Jagtial, Peddapalli districts to its south. About 12 km (7.5 mi) after entering Telangana it merges with the back waters of the Sriram Sagar Dam. The river after emerging through the dam gates, enjoys a wide river bed, often splitting to encase sandy islands. The river receives a minor but significant tributary Kadam river. It then emerges at its eastern side to act as a state border with Maharashtra only to later enter into Bhadradri Kothagudem district. In this district, the river flows through an important Hindu pilgrimage town – Bhadrachalam.
The river further swells after receiving a minor tributary Kinnerasani River and exits into Andhra Pradesh.
