Explanation: The Polavaram project is a significant irrigation and multipurpose project located in Andhra Pradesh, India. It is situated on the Godavari River, which is the second-longest river in India and a vital water resource for the state. The project includes a dam, a spill channel, and extensive irrigation facilities designed to provide water for agriculture, drinking, and other purposes.
The Godavari River originates in the Western Ghats in Maharashtra and flows through several states before reaching Andhra Pradesh. It is a crucial river for the state, providing water for irrigation, drinking, and industrial use. The Polavaram project aims to harness the water resources of the Godavari River to benefit the agricultural and economic development of Andhra Pradesh.
The project's spill channel concrete works were recognized by the Guinness Book of World Records for completing 32,315.5 cubic meters of concrete in 24 hours. This achievement highlights the scale and importance of the project, which is considered a significant development for the state.
It is important to note that the Polavaram project is not located on the Krishna River, which is another major river in Andhra Pradesh but is a different river system. The Kaveri River is primarily located in Karnataka and Tamil Nadu, and the Mahanadi River is in Odisha. Therefore, the correct answer is that the Polavaram Dam is located across the Godavari River.
Understanding the location and significance of the Polavaram project is crucial for comprehending the water management and development efforts in Andhra Pradesh. The project's success in setting a world record for concrete works also underscores the engineering and construction capabilities involved in such large-scale projects.
