The Kaveri rises in the Brahmagri range of the Western Ghats and it reaches the Bay of Bengal in south of Cuddalore in Tamil Nadu. The total length of the river is about 760 km. Its main tributaries are Amravati, Bhavani, Hemavati and Kabini. Its basin drains parts of Karnataka, Kerala and Tamil Nadu.

Detailed Explanation

The Kaveri River has its source in the Brahmagri range, which is part of the Western Ghats, a mountain range in India. It flows through various states and eventually empties into the Bay of Bengal near Cuddalore. The river is approximately 760 kilometers long and has several main tributaries that contribute to its flow. These tributaries, including Amravati, Bhavani, Hemavati, and Kabini, play a vital role in the river's system. The Kaveri basin itself encompasses parts of the states of Karnataka, Kerala, and Tamil Nadu, showcasing its extensive geographical range.

Examples & Analogies

Imagine the Kaveri River as a long straw that draws water from a large bowl (the river basin). The tributaries are like smaller straws that bring extra water from different surrounding areas, ensuring that the main 'straw' has enough liquid to maintain its flow towards the 'drinking glass' (the Bay of Bengal).

The river Kaveri makes the second biggest waterfall in India, known as Shivasamudram Falls. The hydroelectric power generated from the falls is supplied to Mysuru, Bengaluru and the Kolar Gold Field.

Detailed Explanation

The Kaveri River is noteworthy for its waterfalls, particularly the Shivasamudram Falls, which is the second largest waterfall in India. This natural feature is not only a tourist attraction but also serves a practical purpose. The water that cascades down the falls is harnessed to generate hydroelectric power, which is vital for cities such as Mysuru and Bengaluru, as well as for the Kolar Gold Field. This illustrates how natural resources can be utilized for human benefit while also enhancing the beauty of the landscape.

Examples & Analogies

Think of the Kaveri River as a giant water wheel that not only provides us with water but also powers the machines that light up our homes and run our city. Just like how farmer’s wheel is essential to drawing water from the well, the Kaveri provides both resources and energy, showing how nature contributes to our day-to-day lives.

Besides these major rivers, there are some smaller rivers flowing towards the east. The Damoder, the Brahmani, the Baitar ni and the Subarnrekha are some notable examples. Locate them in your atlas.

Detailed Explanation

In addition to the Kaveri, there are smaller rivers in the region, like the Damoder and the Brahmani, that flow eastward. Understanding the Kaveri Basin is important not only for its major river but also for recognizing these smaller waterways that contribute to the ecosystem and hydrology of the area. By exploring these rivers on a map, students can visualize the larger network of waterways that intertwine and affect the environment and communities in South India.

Examples & Analogies

Consider the Kaveri Basin as a large neighborhood where the Kaveri is the main road, and the smaller rivers are side streets. Just like how side streets provide access to different parts of a neighborhood, the smaller rivers help deliver water and nutrients to various regions within the basin, supporting diverse habitats and communities.
