Explanations:The Nagarjuna Sagar Dam is a significant hydroelectric and irrigation project located in the state of Andhra Pradesh, India. It is situated on the River Krishna, which is one of the major rivers in the Indian subcontinent. The River Krishna originates in the Western Ghats in Maharashtra and flows through the states of Karnataka and Andhra Pradesh before emptying into the Bay of Bengal.
The construction of the Nagarjuna Sagar Dam began in 1955 and was completed in 1966. It is a masonry dam and is known for its impressive height and the large reservoir it creates. The dam is a crucial part of the Krishna River Project, which aims to provide water for irrigation, generate hydroelectric power, and control floods in the region.
Understanding the geographical context of the Nagarjuna Sagar Dam is essential for students preparing for competitive examinations, particularly those related to geography and general knowledge. The River Krishna is a significant river in the region, and its importance is highlighted by the presence of major projects like the Nagarjuna Sagar Dam.
It is important to note that the River Krishna is not the only major river in Andhra Pradesh. The state is also home to the River Godavari, which is the second-longest river in India. However, the Godavari does not flow through the location of the Nagarjuna Sagar Dam. Similarly, the River Tapi is located in western India and is not related to the geographical features of Andhra Pradesh.
Therefore, the correct answer is that the Nagarjuna Sagar Dam is constructed on the River Krishna. This information is crucial for students to remember, as it is a common question in competitive examinations and general knowledge tests.
