Indian Hydroelectric Projects and Dams

The Hanumannagar barrage is associated with the Kosi Project, a major irrigation and flood control initiative in Bihar. The main canal of the Kosi Project is taken from the Hanumannagar barrage. The other options refer to different dam projects: Bhakra Nangal (on Sutlej River), Indira Gandhi Project (on Beas River), and Hirakud Dam (on Mahanadi River).

The Tungabhadra River is a tributary of the Krishna River and flows through both Karnataka and Andhra Pradesh. The dam was built as a joint project between these two states to provide irrigation and hydroelectric power.

The Gandak Project is a joint venture between India and Nepal, constructed on the Gandak River. It serves irrigation and hydroelectric power generation needs for both countries, similar to the Kosi Project.

The Chambal Project is a multi-purpose project on the Chambal River. It consists of a series of dams including Gandhi Sagar Dam (first in the series) and Jawahar Sagar Dam (second), used for irrigation and power generation.

The Nagarjunasagar Project on the Krishna River is one of India's largest irrigation projects. It has an irrigation potential of about 8-9 lakh hectares, making it the project that irrigates approximately 8,67,000 hectares as mentioned.

The Chambal Project has an irrigation capacity of approximately 5 lakh (500,000) hectares. This multi-purpose project includes Gandhi Sagar, Jawahar Sagar, Rana Pratap Sagar, and Kota dams primarily serving Madhya Pradesh and Rajasthan.

The Hirakud Dam on the Mahanadi River in Odisha is the longest dam in India and was built primarily to control floods in the Mahanadi delta region. It also serves irrigation and power generation purposes.

The Balimela hydroelectric project is located on the Sileru River in Odisha (formerly Orissa). It is a joint project between Odisha and Andhra Pradesh and was constructed to harness the hydroelectric potential of the Eastern Ghats region.
