Study Notes

Landform of West Bengal

West Bengal's landform comprises three distinct physiographic units: Northern Mountain, Western Plateau, and The Plains.

Northern Mountain Region

The Northern Mountain Region encompasses the Darjeeling Himalayan region.
The region is situated on the north-western side of West Bengal.
The Teesta River divides the region into two parts: the Singalila range and the Darjeeling range.
The Singalila range holds the highest point in West Bengal, the Sandakfu peak at 3,636 meters.
Sandakfu & Phalut are the only places in West Bengal where Mount Everest is visible.
The Buxa-Jayanti Hills, remnants of the Siwaliks, are found in the Jalpaiguri and Alipurduar districts.

Western Plateau Region

The Western Plateau, a part of the Chhota Nagpur plateau, is characterized by small hills called "Dungi" or "Tila".
The region comprises Purulia, western parts of Birbhum, Bankura, Bardhaman, and West Midnapore districts.
The highest peak in the Ayodhya hills is Gorga Buru.
The region is dissected by rivers originating from the Chotanagpur plateau.
The area between the Kansai and Subarnarekha rivers in Purulia district is known as "Barabhum".
Bakreswar in Birbhum district is home to a hot water spring.

The Plains

The Plains of West Bengal extend from Siliguri to the coast of the Bay of Bengal.
This region is divided into two sub-regions: Plains of North Bengal and Plains of South Bengal.

Plains of North Bengal

The Plains of North Bengal stretch from Siliguri to the north bank of the Ganges River.
The region is further divided into the Terai-Duars region and the Northern Plain.

Terai-Duars Region

The Terai-Duars region consists of sand, gravel, and pebbles brought down from the Himalayas by rivers.
The Teesta River divides the region into Terai (western) and Duars (eastern).
The Duars region is further subdivided into Siliguri (western), Jalpaiguri (middle), and Alipur (eastern) duars.

Northern Plain

The Northern Plain extends from the southern end of the Terai region to the northern bank of the Ganges.
It is further classified into:
- Diara: New alluvium brought by the Kalindi River.
- Barendrabhumi: Old alluvium found in south West Dinajpur and northeast Malda.
- Tal: Lakes or wetlands formed by floodwaters, numerous between the Mahananda and Kalindi rivers.

Plains of South Bengal

The delta plain formed by the lower course of the Ganges River constitutes the entire plains of South Bengal.
The region is classified into four sub-divisions:

Ganga Delta Plain

The Ganga Delta Plain is further categorized into three distinct plains:
- Moribund Delta Plain: Old delta, covers Nadia and eastern Murshidabad districts.
- Mature Delta Plain: Newer delta, covers Hooghly, Howrah, parts of Bardhaman, and East Midnapore districts.
- Active Delta Plain: On-going delta formation, covers eastern South 24-Parganas and southern North 24-Parganas districts.
New islands, such as Purbasha, are often formed in the southern part of the active delta.

Rahr Plain

The Rahr Plain lies between the delta plain and the Western Plateau.
It is formed by silt deposition carried out by tributaries of the Ajay, Damodar, Mayurakashi, and Rupnarayan rivers.
The soil of the Rahr Plain is red due to the flow of rivers over the laterite soil of the Western Plateau.

Sandy Coastal Plain

This plain lies along the Bay of Bengal in East Midnapore.
It is formed by sand and mud deposition by rivers and wind.
It features numerous sand dunes.

Sundarban Plain

The Sundarban Plain encompasses the southern parts of North and South 24-Parganas, especially the Sundarbans.
It is characterized by:
- Alluvial low plains
- Muddy and saline water
- Numerous tributaries
- Islands and estuaries
The Sundarbans is the largest mangrove forest in the world.
The region is named after the abundant presence of "Sundari" trees.
It was declared a World Heritage Site by UNESCO in 1987.
Many tidal rivers, such as Bartala, Saptamukhi, Jamina, Malta, and Gosaba, flow through the region.
