POLAVARAM PROJECT - ENVIRONMENT

News: 892 acres to be submerged in backwater of Polavaram 

What's in the news?

       Telangana has informed the Polavaram Project Authority (PPA) that the floods in Godavari in July inundated 103 villages, submerging 40,446 acres in the State.

Polavaram Project:

       The Polavaram Project is an under construction multi-purpose irrigation project on the Godavari River in the Eluru District and East Godavari District in Andhra Pradesh.

       The project has been accorded National project status by the Union Government of India.

       Its reservoir back water spreads up to the Dummugudem Anicut (i.e. approx 150 km back from Polavaram dam on main riverside) and approx 115 km on Sabari River side.

       Thus back water spreads into parts of Chhattisgarh and Odisha States.

       It gives a major boost to the tourism sector in Godavari Districts as the reservoir covers the famous Papikonda National Park.

River Godavari:

       The Godavari, also known as the Dakshin Ganga, is Peninsular India's biggest river system.

       The Godavari basin spans Maharashtra, Andhra Pradesh, Chhattisgarh, and Odisha, as well as minor sections of Madhya Pradesh, Karnataka, and the Union territory of Puducherry (Yanam), covering around 3 lakh square kilometers.

       At a height of 1,067 meters, the Godavari River emerges from Trimbakeshwar in Maharashtra's Nashik region, roughly 80 kilometers from the Arabian Sea.

       The Godavari is 1,465 kilometers long from its source to its outflow into the Bay of Bengal.

       In its lowest levels, the Godavari basin is prone to floods.

       Coastal locations are prone to cyclones.

       The flat geography of the delta zones causes drainage congestion.

Tributaries:

       The tributaries on the left bank are more numerous and greater in size than those on the right bank.

       Dharna, Penganga, Wainganga, Wardha, Pranahita, Pench, Kanhan, Sabari, Indravati, are Left Bank Tributaries.

       Pravara, Mula, Manjra, Peddavagu, Maner, are Right Bank tributaries.

       The river separates into two major streams below Rajahmundry, the Gautami Godavari on the east and the Vasishta Godavari on the west, and creates a huge delta before emptying into the Bay of Bengal.

       The Godavari delta is lobate in shape, with a circular bulge and several distributaries.

Festival: The Kumbh Mela is also held at Nashik, on the banks of the Godavari river.
