Consider the hydrological features, tributary orientations, and major water resource structures of the Cauvery River basin in Peninsular India. Which of the following statements regarding the Cauvery River system are correct?
- Unlike most other Peninsular rivers, the Cauvery River basin receives rainfall from both the Southwest Monsoon during summer and the Northeast Monsoon during winter, resulting in a relatively less seasonal fluctuation in its discharge.Answer
- BThe Shimsha, Hemavati, and Arkavathi rivers are major right-bank tributaries of the Cauvery River, whereas the Kabini, Bhavani, and Amaravati are its primary left-bank tributaries.
- Along its upper course in Karnataka, the Cauvery River splits into two branches to enclose sacred riverine islands including Srirangapatna and Sivasamudram before cascading down the Sivasamudram Falls.Answer
- DThe Stanley Reservoir, impounded by the Mettur Dam across the Cauvery River, is located near Talakaveri in the Kodagu district of Karnataka.
Answer
The statements confirming that the Cauvery River receives rainfall from both monsoons and that it forms the riverine islands of Srirangapatna and Sivasamudram are correct.
The Cauvery River system is unique among Peninsular rivers due to its regime: its upper basin is fed by the Southwest monsoon during summer and its lower basin by the Northeast monsoon during winter, which keeps its water flow comparatively stable. Furthermore, the river bifurcates and reunites in Karnataka to form the famous riverine islands of Srirangapatna and Sivasamudram.
