The Western Ghats, is a mountain range that covers an area of 160,000 square kilometres (62,000 sq mi) in a stretch of 1,600 kilometres (990 mi) parallel to the western coast of the Indian peninsula, traversing the states of Kerala, Tamil Nadu, Karnataka, GOA, Maharashtra and Gujarat. It is a UNESCO World Heritage Site and is one of the eight hot-spots of biological diversity in the world. It is sometimes called the Great Escarpment of India. It contains a very large proportion of the country's flora and fauna, many of which are only found in India and nowhere else in the world. According to UNESCO, the Western Ghats are older than the Himalayas. They influence Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer. The range runs north to south along the western edge of the Deccan Plateau, and separates the plateau from a narrow coastal plain, called Konkan, along the Arabian Sea. A total of thirty-nine areas in the Western Ghats, including national parks, wildlife sanctuaries and reserve forests, were designated as world heritage sites in 2012 – twenty in Kerala, ten in Karnataka, six in Tamil Nadu and four in Maharashtra.

Periyar is the longest river and the river with the largest discharge potential in the Indian state of Kerala. It is one of the few perennial rivers in the region and provides drinking water for several major towns. The Periyar is of utmost significance to the economy of Kerala. It generates a significant proportion of Kerala's electrical power via the Idukki Dam and flows along a region of industrial and commercial activity. The river also provides water for irrigation and domestic use throughout its course besides supporting a rich fishery. Due to these reasons, the river has been named the "Lifeline of Kerala". Kochi city, in the vicinity of the river mouth draws its water supply from Aluva, an upstream site sufficiently free of seawater intrusion. Twenty five percent of Kerala's industries are along the banks of river Periyar. These are mostly crowded within a stretch of 5 kilometres (3 mi) in the Eloor-Edayar region (Udhyogamandal), about 10 kilometres (6 mi) north of Kochi harbor.
The Anaimalai or Anamala Hills, also known as the Elephant Mountains, are the range of mountains that form the southern portion of the Western Ghats and span the border of Tamil Nadu and Kerala in Southern India.

Though Chalakudy river in strict geological sense is a tributary of the Periyar river, for all practical purposes it is treated as a separate river by Government and other agencies. The River has gained its name, since it flows along the banks of the Chalakudy Town, the major settlement along the course of the river. It is perhaps the most unpolluted and pristine river in the state and even in India due to the limited amount of industries and wastage disposal around it. Chalakudy River and its basin area were one of the most affected rivers during the 2018 Kerala floods.
