Key Points

  • Godavari River:
    • The Godavari is the largest Peninsular river system. It is also called the Dakshin Ganga.
    • Source: Godavari river rises from Trimbakeshwar near Nasik in Maharashtra and flows for a length of about 1465 km before outfalling into the Bay of Bengal.
    • Drainage Basin: The Godavari basin extends over states of Maharashtra, Telangana, Andhra Pradesh, Chhattisgarh and Odisha in addition to smaller parts in Madhya Pradesh, Karnataka and Union territory of Puducherry.
    • Tributaries: Pravara, Purna, Manjra, Penganga, Wardha, Wainganga, Pranhita (combined flow of Wainganga, Penganga, Wardha), Indravati, Maner and the Sabri.
    • Cultural Significance: Kumbh Mela also takes place on the banks of the Godavari river in Nashik.
      • Other locations for Kumbh are the Shipra river in Ujjain, the Ganges in Haridwar, and the confluence of the Ganges, Yamuna, and the mythical Saraswati river in Prayag.
    • Godavari River Dispute: Godavari river water sharing is bone of contention among Andhra Pradesh, Madhya Pradesh, Chhattisgarh, Odisha, and Karnataka.
    • Important Projects on Godavari:
      • Polavaram Irrigation Project.
      • Kaleshwaram.
      • Sadarmatt Anicut across river Godavari is one among the two irrigation projects in the International Commission on Irrigation and Drainage (ICID) Register of Heritage Irrigation Structures.
      • Inchampalli: The Inchampalli project is proposed on the Godavari River about 12 km downstream of the confluence of Indravati with the Godavari River in Andhra Pradesh.
        • It is a joint project among the States of Maharashtra, Madhya Pradesh, Telangana and Andhra Pradesh.
      • Sriram Sagar Project (SRSP): The Sriram Sagar Project is a multipurpose project, located across the Godavari River near Pochampad of Nizamabad District in Telangana.

  • Polavaram Irrigation Project:
    • Polavaram Project is located in Andhra Pradesh on the river Godavari, near Polavaram village.
    • It is a multi-purpose irrigation project as the project once completed will provide Irrigation benefits and will generate HydroElectric Power.
      • In addition, this project will also supply drinking water.
    • It will facilitate an inter-basin transfer to the Krishna river basin through its Right canal.
    • It will also provide indirect benefits such as development of Pisciculture (breeding and rearing of fish), tourism and urbanisation.
    • The Project has been accorded national project status by the union government in 2014 (under Section-90 of Andhra Pradesh Reorganization Act, 2014).

Cofferdam

  • A cofferdam is defined as a temporary barrier in or around a body of water which allows the process of de-watering, diversion, or damming of water within an enclosed area.
  • The major purpose of any cofferdam type is to hold back overwhelming or inconvenient waters and create a dry work environment.
  • This allows a project to proceed with as little resistance and as much safety as possible.
