The Western Coastal Plains are run between the west coast of India and the Western Ghats highlands, beginning at the Tapi River. Between the Western Ghats and the Arabian Sea lie the lowlands. The plains start in the north and terminate in the south, with Gujarat in the north and Tamil Nadu in the south. Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu are all part of it. This article will explain to you about the Western Coastal Plain which will be helpful in Geography preparation for the UPSC Civil service exam.

Western Coastal Plains of India

• The Western Coastal Plains go from Kerala in the south to Gujarat in the north, passing through Karnataka, Goa, and Maharashtra along the way.
• The western coastal plains run about 1500 kilometres north to south, with widths ranging from 10 to 25 kilometres.
• The West Continental Shelf is at its broadest near the coast of Bombay. This region is rich in oil.
• There are several gorgeous lagoons along the Malabar Coast, making it a popular tourist destination.

• The western shore is narrower than the east.
• Submerged coastal plains may be found in the western coastal plains.
• The city of Dwaraka, which was originally a part of the Indian mainland and is located along the west coast, is said to have submerged beneath the water. Because of the submergence, it is a small band with natural circumstances for the construction of ports and harbours.
• The western coast is classified into four sections:
• Kachchh and Kathiawar coast
• Konkan coast
• Kanada coast
• Malabar coast
• There are several gorgeous lagoons along the Malabar Coast, making it a popular tourist destination.
• The western coast of India is narrower than the eastern.
• It's made up of alluvium brought down by short streams from the Western Ghats.
• Coves (small bays), creeks (short, protected waterways such as an inlet in a coastline or a channel in a marsh), and estuaries dot the landscape.
• The most major estuaries are the Narmada and Tapi.
• The Vembanad Lake is the largest of the Kerala coast's lakes, lagoons, and backwaters (Malabar Coast).

Kachchh and Kathiawar coast

• The Indus River deposits silt at Kachchh, which was formerly a gulf. During the monsoons, the land of Kachchh is separated into two parts:
• the Great Rann in the north
• the Little Rann in the east.
• Kathiawar, on the other hand, is located to the south of Kachchh.
• Despite being an extension of the Peninsular plateau (since Kathiawar is built of Deccan Lava and there are tertiary rocks in the Kutch area), Kutch and Kathiawar are still recognised as vital parts of the Western Coastal Plains because they have been levelled.
• The Kutch Peninsula was an island with oceans and lagoons surrounding it. The material transported by the Indus River, which used to flow through this area, subsequently filled these seas and lagoons. Due to a lack of rain in recent years, the environment has become parched and semi-desert.
• The Great Rann is a salt-soaked plain to the north of Kutch. The Little Rann, its southern extension, sits on the shore and south-east of Kachchh.
• Though Kutch and Kathiawar are an extension of the Peninsular Plateau (since the Kathiawar Peninsula is to the south of the Kachchh), they are not part of the Peninsular Plateau.
• The Mandav Hills form the middle highland, from which minor streams flow in all directions (Radial Drainage).
• The highest peak is Mt. Girnar (1,117 m), which is volcanic in nature.
• The Gir Range is found in the Kathiawar peninsula's southern region. It is known for being the home of the Gir lion and is shrouded in lush woods.

Konkan coast

• The Konkan is a strip of land stretching from Thane in the north to Karwar in the south on the west Indian coast, with the Arabian Sea to the west and the Western Ghats to the east.
• Among the mountainous slopes rising up into the Deccan Plateau tablelands are several river basins and riverine islands in the hinterland east of the coast.
• It is bordered on the east by the Western Ghats mountain range (also known as Sahyadri), west by the Arabian Sea, north by the Ganga River, and south by the River Aghanashini.
• Cliffs, shoals, reefs, and islands in the Arabian Sea are all examples of marine erosion.
• Around Mumbai, the Thane Creek is an important embayment (a bay formed by a dip in the shoreline) that serves as a natural harbour.

Kanada coast

• Kannada Coast is a coastal lowland in Karnataka, India's westernmost state.
• It is bordered on the north by the Konkan, on the east by the Western Ghats, on the south by the Kerala Plains, and on the west by the Arabian Sea.
• The plain is narrow, with an average width of 30-50 kilometres and a maximum of 70 kilometres near Mangalore.
• Streams that originate in the Western Ghats down steep hillsides and form waterfalls in certain areas.
• The Sharavati creates a magnificent cascade known as Gersoppa (Jog) Falls, which is 271 metres high, when it descends such a steep hill.
• Angel Falls (979 metres) in Venezuela is the world's tallest waterfall. Tugela Falls (948 m) in South Africa's Drakensberg mountains is the second tallest.
• On the seashore, the marine terrain is particularly distinct.
• The Kali Nadi, Gangavali, Bedti, Tadri, Sharavati, and Netravati rivers, which have carved out small valleys with high grades and run in a westerly direction, drain the shore.
• In the south, alluvial soils are found. The rest of the shore is covered with barren red soil that is frequently gravelly and sandy.

Malabar coast

• The Malabar Coast is located on the Indian subcontinent's southwest coast.
• Geographically, it includes the wettest parts of southern India, since the Western Ghats, especially on their westward-facing mountain slopes, intercept the moisture-laden monsoon rains.
• This plain is substantially larger than the plain of Karnataka. It's a flat, low-lying plain.
• The presence of lakes, lagoons, backwaters, spits, and other water bodies is a distinctive feature of the Kerala coast.
• The backwaters, also known as kayals, are shallow sea inlets or lagoons that run parallel to the shore.
• The greatest of these is the Vembanad Lake, which is 75 kilometres long and 5 kilometres broad and gives birth to a 55-kilometre-long spit of land known as Marine Landforms.
• From the western coast of Konkan to the subcontinent's point at Kanyakumari, the phrase is used to refer to the whole Indian coast.
• On the Malabar Coast, the peak of Anamudi, which is also India's highest point outside of the Himalayas, and Kuttanad, which is India's lowest point, are located.
• Kuttanad, popularly known as Kerala's Rice Bowl, is the lowest point in India and one of the few areas on the planet where agriculture takes place below sea level.

Significance of Western Coastal Plain

• India's peninsular plateau is rich in valuable resources, high-quality coal, iron ore, and a large population.
• The peninsular plateau of India includes the Western Coastal Plains.
• The Western Coastal Plains are named from their location on the plateau's western side.
• These plains provide the best biodiversity and weather conditions for humans and other species to live in.
• It is the thinnest in Goa and the thickest in Kerala.
• From an economic standpoint, such lengthy coasts are critical for the country.
• The majority of individuals who live along with the shore work in the fishing industry.
• Over the years, several seaports have sprouted along the shorelines. These ports assist the country in conducting international trade via the sea.
• There are two gulfs on its northern side: the Gulf of Khambhat and the Gulf of Kutch.
• The rivers that run along the shore generate estuaries, which are suitable for pisciculture. Because there is less coastline land in this region, it will be more affected by global warming.

Conclusion

The peninsular plateau of India is abundant in important resources, such as high-quality coal and iron ore, as well as a big population. The Western Coastal Plains are part of India's peninsular plateau. The Western Coastal Plains get their name from the fact that they are located on the plateau's western side. From Kerala in the south to Gujarat in the north, the Western Coastal Plains run through Karnataka, Goa, and Maharashtra.
