Question

Which river system originates from Sivagiri Hill and includes tributaries like Mullayar, Muthirapuzha, and Idamalayar?

• A. Bharathapuzha
• B. Periyar
• C. Chaliyar
• D. Chalakudy

Answer 1

Answer:

B. Periyar

• Correct Answer: Option B - Periyar

• The Periyar River is one of the longest rivers in Kerala and originates from Sivagiri Hill in the Western Ghats. It is the second-longest river in Kerala after Bharathapuzha. The river system includes several important tributaries:

• Mullayar - Joins the Periyar at Mullakudy

• Muthirapuzha - Originates from the Anamudi hills

• Idamalayar - A major tributary that joins the main river

• The Periyar flows through districts like Idukki and Ernakulam before emptying into the Arabian Sea. The river is significant for Kerala as it supports the Idukki and Periyar Valley hydroelectric projects and provides water for irrigation and drinking water supply to many parts of central Kerala. The Periyar is also known as the "Lifeline of Kerala" due to its crucial role in the state's economy and ecology.

• The other options are incorrect:

• Bharathapuzha originates from Anamalai Hills

• Chaliyar originates from Illambalari Hills in Wayanad

• Chalakudy River is a tributary of the Periyar, not an independent river system with the mentioned tributaries
