Explanation: The Periyar River is a significant geographical feature of Kerala, India. It is the longest river in the state, originating in the Western Ghats and flowing through several districts before draining into the Laccadive Sea. The river plays a crucial role in the state's geography, supporting agriculture, providing water for domestic use, and serving as a habitat for various species of flora and fauna.
The Periyar River has a total length of approximately 244 kilometers (152 miles). It begins its journey in the Anamalai Hills of the Western Ghats, specifically in the Anaimalai Wildlife Sanctuary. The river flows through the districts of Idukki, Ernakulam, Thrissur, and Malappuram before reaching the Laccadive Sea. Along its course, the Periyar River forms several tributaries and passes through important cities and towns, including Periyar, Thodupuzha, and Kochi.
The Periyar River is not only a geographical feature but also a cultural and historical landmark. It is associated with the Periyar Tiger Reserve, which is a protected area known for its biodiversity. The river is also the site of the Mullaperiyar Dam, a controversial structure that has been a subject of dispute between Kerala and Tamil Nadu due to concerns over water sharing and safety.
Understanding the geography of the Periyar River is essential for students preparing for competitive exams related to Kerala, such as the Kerala Public Service Commission (KPSC) exams. It is important to recognize that while the Periyar River does have a small portion in Tamil Nadu, its primary course and origin are in Kerala. This distinction is crucial for correctly identifying the state associated with the Periyar River.
In summary, the Periyar River is a significant river in Kerala, originating in the Western Ghats and flowing through several districts before reaching the Laccadive Sea.
