Explanation: The Tungabhadra River is a significant river in the Indian subcontinent, primarily flowing through the states of Karnataka and Andhra Pradesh. It is a major tributary of the Krishna River, which is one of the longest rivers in India. The Tungabhadra River originates in the Western Ghats in Karnataka, specifically in the Chikmagalur district. It flows through the districts of Shimoga, Chitradurga, Bellary, and Raichur in Karnataka before entering Andhra Pradesh.
The river's course is approximately 550 kilometers long, with the majority of its length lying within Karnataka. The river basin covers an area of about 7,650 square kilometers in Karnataka. The Tungabhadra River is crucial for irrigation, drinking water supply, and hydroelectric power generation in the region. The Tungabhadra Dam, constructed across the river, is a significant water resource project that provides water for irrigation and power generation.
The river's flow through Karnataka is extensive, and it forms a vital part of the state's geography and economy. The river basin supports agriculture, particularly in the districts of Raichur and Bellary, where it is used for irrigation. The river also plays a significant role in the cultural and historical landscape of Karnataka, with several ancient temples and historical sites located along its banks.
In contrast, the river flows through a smaller portion of Andhra Pradesh and does not significantly impact Telangana or Orissa. Therefore, the major part of the Tungabhadra River lies in Karnataka, making it the correct answer to the question.
Understanding the geographical distribution of rivers is essential for comprehending the water resources and economic activities of a region. The Tungabhadra River's course through Karnataka highlights the state's importance in managing and utilizing this significant water resource.
