Coastal Plains of India


  • The coastal plain of India is situated on the coast of the Arabian Sea (Gujarat) in the west and along the Bay of Bengal (West Bengal) in the east.
  • They are called East Coastal Plains and West Coastal Plains according to their location east or west of the peninsula.
  1. East coastal plain
  2. West coastal plain

 East coastal plain-

  • Due to the slow gradient of the rivers in the east coastal plain in India, their flow is very slow, due to which when it collides with the strong waves of the sea, then its water flows into hundreds of streams and the rivers slow their alluvial deposits. This is the reason why the delta is formed as a result.
  • The delta is constantly running towards the sea.
  • The eastern coastal plain is formed by the joining of the delta region of hundreds of rivers, hence it is an alluvial deposit area, hence the eastern coastal plain is very fertile and is famous for paddy cultivation such as delta of Mahanadi, the delta of Godavari, Krishna and Kaveri. Delta of rivers.
  • The east coastal plain extends from the mouth of the Hooghly River (West Bengal) to Kanyakumari. Which is divided into two parts-
  1. Coromandel Coast

  2. North Sircar Coast

It has less lagoon than the west coast, while it can be divided according to the states:

  • Orissa Coast or Utkal Coastal Plain
  • Andhra Coastal Plain
  • Tamil Nadu Coastal Plain or Coromandel Coast

Western Coastal Plain

  • The West Coast of India is narrower than the East Coast.
  • Due to the gradient of the Western Ghats being very intense, the flow from the Western Ghats to the rivers flowing is very fast, due to which the rivers do not form deltas before joining the Arabian Sea, but form the estuary.
  • Majority of Malabar coast comes in Kerala and hence it is called Kerala coast.
  • There is a lot of lagoon lake here. The lagoon lake has saline water as it is in contact with the sea.
  • Lagoon lakes in Kerala are locally called Kayal.

The western coastal plain extends from Gujarat to Kanyakumari. Which is divided into three parts-

  1. Gujarat to Mumbai coast – Kathiawar Beach 
  2. Coast from Mumbai to Goa – Konkan
  3. Coast Goa to Kanyakumari – Malabar Coast
  • On the west coast, the rivers fall into the Arabian Sea at a rapid speed and push the seawater back, creating a tidal situation here.
  • Such as the Narmada and Tapi rivers in Gujarat, Sharavati in Karnataka, Mandvi and Jowari in Goa, Bharatpura in Kerala, Periyar forms the Jauvanadamukh.
