Explanations:The Kaveri River, also known as Cauvery, is a significant river in southern India, flowing through the states of Karnataka and Tamil Nadu. It is an important water resource for both states and is a subject of considerable interest in geography and environmental studies. The river has several tributaries that contribute to its flow and water volume.
Among the options provided, Hemavathi, Simsha, and Arkavathi are all tributaries of the Kaveri River. Hemavathi originates in the Western Ghats and flows through the districts of Hassan and Mysuru in Karnataka, joining the Kaveri at Srirangapatna. Simsha is another tributary that flows through the districts of Bangalore Rural and Tumakuru in Karnataka, merging with the Kaveri near Srirangapatna. Arkavathi also originates in the Western Ghats and flows through the districts of Bangalore Rural and Tumakuru, joining the Kaveri near Kanakapura.
On the other hand, Bhima is not a tributary of the Kaveri River. It is a major tributary of the Krishna River, which flows through the states of Maharashtra and Karnataka. The Bhima River originates in the Western Ghats and flows through the districts of Pune and Solapur in Maharashtra before entering Karnataka and joining the Krishna River. This makes Bhima a part of the Krishna River system, not the Kaveri River system.
Understanding the tributaries of a river system is crucial for comprehending the geographical and hydrological characteristics of a region. It helps in managing water resources, planning irrigation systems, and understanding the ecological impact of river systems. In the context of competitive examinations, knowledge of river systems and their tributaries is often tested to assess a candidate's geographical knowledge and spatial awareness.
