Eastern Coastal Plains

The Eastern Coastal Plains is a stretch of coastal land lying between the eastern edge of the Deccan Plateau and the Bay of Bengal in the west. The disjointed mountain range of Eastern Ghats forms a rough western boundary of the plains. The plains stretch from the Mahanadi delta to Kaniyakumari at the southern tip of the Indian peninsula and traverses the states of Odisha, Andhra Pradesh, Tamil Nadu and the union territory of Puducherry. It is wider and leveled than the Western Coastal Plains and both the coastal plains meet at Kaniyakumari. The average width of the plains vary between with an average width of . The plains are broadly divided into three subdivisions–Utkal Plains in the north, Andhra plains (Circars) in the center, and Tamil Nadu plains (Coromandel) in the south. == Utkal plains ==

The Utkal Plains form a major part of Odisha and stretch from the southern end of the Indo-Gangetic plains to the Andhra plains in the south. The region is drained by rivers such as Mahanadi, Brahmani, Baitarani, and Subarnarekha. The region consists of fertile red and black soil interspersed with gneiss and sandstone rock formations formed during the paleogene and neogene eras. The sands in the beaches consists of small granites and zircon. The vegetation consists of littoral forests on the coasts and tropical moist deciduous forests inland. Chilika Lake, the largest lake in the region is a brackish lagoon. == Andhra plains ==

The Andhra Plains (Circars) extend from the south of the Utkal Plain to Pulicat Lake, north of Chennai. The coastal plains are widest in the region with a significant portion formed by the deltas of the largest peninsular rivers Godavari and Krishna. The deltas have advanced towards the Bay of Bengal, which has pushed the Kolleru Lake inwards. The Pulicat Lake is interrupted by a sand spit which forms the island of Sriharikota. == Tamil Nadu plains ==

The Tamil Nadu Plains (Coromandel) stretches for from the south of Pulicat Lake to Kanniyakumari at the southern end of the Indian peninsula. The average width is about with the plains widest at the Kaveri delta at . The fertile soil and irrigation facilities have made the Kaveri delta region as one of the major centers of agriculture. The coast itself has sparse vegetation with marshlands dotted with coconut and palm trees. == See also ==
