Features of the western coastal plains:

  • The western coastal plains extend from Rann of Kuchh in Gujarat (North) to Kanyakumari in Tamilnadu (South).
  • The coastal plains spread to 1500 km in length and the average width is 50 km.
  • The western coastal plains pass through six states  Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamilnadu.
  • These coastal plains extend to continue except Gujarat plains.
  • The north and south sections of these coastal plains are wider but the central section is very narrow.

Division of western coastal plains:

The western coastal plains divided into three sections:

(A) Gujarat coastal plains:

  • Gujarat coastal plains are formed from the deposition activities of rivers such as Mahi, Luni, Sabarmati, and Tapi.
  • Gujarat coastal plains divided into two parts (a) Rann of Kuchh (b) the Kathiawar Peninsula.
  • Rann of Kuchh: It is the northern part of Gujarat's coastal plains. It consists of Great Rann and Little Rann. The Rann of Kuchh is a salt-soaked plain. The land is barren and infertile in this region.
  • Kathiawar Peninsula: It is located between the Gulf of Kutch and the Gulf of Khambhat. This region is also known as " Saurashtra".  The Kathiawar Peninsula contains volcanic hills (Mandav hills and Girnar hills) and is made of basaltic lava. Mt. Girnar is the highest peak of Gujarat state and situated in this region.
(B) Konkan coastal plains:
  • Konkan coastal plains extend from Daman to Goa. These coastal plains pass through Daman, Maharashtra, and Goa.
  • These coastal plains are flat and made of basaltic rocks.

(C) Malabar Coastal Plains:

  • Malabar Coastal Plains strat from west of Konkan plains (Karnataka) to Kanyakumari( Tamilnadu). 
  • These coastal plains pass through Karnataka, Kerala, and Tamilnadu.
  • The coastal plains of Karnataka are also known as " Kanara" or "Karavali".  This is the narrowest part of the western coastal plains.
  • It has the characteristic lagoon and backwaters of Malabar Coastal Plains. eg. Vembanad(the largest lake of India) and Asthamudi etc.

The climate of western coastal plains of India:

  • Western coastal plains have humid or sub-humid climate conditions but Gujarat coastal plains' climate is arid or semi-arid.
  • It receives more than 2500 mm/year rain except for Gujarat coastal plains. More than 80% of rain receives through the South-West monsoon but Tamilnadu receives rain mainly through the retreating monsoon.


  • On the basis of the Agro-ecological region, Western coastal plains divided into two parts (a) Gujarat coastal plains hot and arid ecoregion (b) other parts of western coastal plains are a hot and subhumid ecoregion.
  • Rice: Main crop, double cropping pattern with rice.
  • Plantations: Coconuts, Bananas, Arecanut, Cashew nut, and Rubber.
  • Pluses and Spices
  • Gujarat coastal plains: Pearl miles, mustard, cluster-bean, Groundnut, and Cotton.
  •  Konkan coastal plains: Rice, Pulses, Coconut, and Rubber.
  • Malabar Coastal Plain: Rice, Pulses, Coconut, Rubber, Spices, and Bananas.


  • The rivers are flowing to the Arabian sea to form estuaries. eg. Narmada, Tapi, Sabarmati, etc.
  • The rivers come to descend into the coastal plains from hills to form waterfalls. eg. Gersoppa falls in the Sharavati river.
  • The main rivers of the western coastal plains are Mahi, Sabarmati, Narmada, Tapi, and Sharavati.


  • The western coastal plains are more indented so that it provides favourable for natural harbours and ports. eg. Kandla port( Gujarat), JLN port( Maharashtra), Mazagaon port( Goa), Mangalore (Karnataka) and Cochin port(Kerala).
  • Intensive agriculture activities in the western coastal plains.
  • Many types of minerals, oil and gas are found in these coastal plains. eg.  Petroleum (Bombay and Ankleshwar), Iron ore and Monozites (Kerala).
  • To provide favourable conditions for pisciculture due to the formation of estuaries by rivers.
  • To attract tourists all over the world for its tourism. eg. Beaches (Goa), Kayals or Backwaters(Kerala), and Marine biodiversity.
