The Northern Plains of India, formed by the alluvial deposits of the Indus, Ganga, and Brahmaputra rivers along with their tributaries, represent the second youngest physiographic region in the country, succeeding the Indian desert.
Bounded by the Shiwalik range to the north, the Desert to the west, the Peninsular Plateau to the south, and the Purvanchal Hills to the east, these plains play a crucial role in the geographical makeup of India.
Comprising mud and sand carried by rivers such as the Indus, Ganga, and Brahmaputra, the Northern Plains are an essential feature with significant importance. For a comprehensive understanding of the Northern Plains of India, read this informative article.
Northern Plains of India
- The Northern Plains of India, emerging as the second-youngest physiographic region in the country after the Indian desert, are delineated by distinct geographical features.
- Bounded by the Shiwalik range to the north, the Desert to the west, the Peninsular Plateau to the south, and the Purvanchal Hills to the east, these plains are shaped by the alluvial deposits of the Indus, Ganga, and Brahmaputra river systems, along with their tributaries.
- Stretching approximately 2400 km from west to east and 150–320 km from north to south, the Northern Plains cover an expansive area exceeding 7 lakh square kilometers.
- Fed by the abundant waters of the mentioned rivers, these plains enjoy a favorable climate and boast fertile alluvial soil, contributing to their high population density.
- The gentle slope of the rivers in this region facilitates a slow flow of water. Ambala, situated in the state of Haryana, marks the highest elevation at 291 meters above sea level, creating a watershed between the Ganga and Indus river systems.
- The Northern Plains, with their ample water supply, agreeable climate, and fertile soil, serve as a vital region supporting a dense population.
- Situated between the Yamuna catchment in the west and the Bangladesh border in the east, the Ganga plains cover a vast region from the Rajmahal hills to the Meghalaya plateau.
- This expansive area, formed by the downwarping of a section of Peninsular India, is shaped by the sedimentation of the Ganga and Brahmaputra rivers.
- Key topographical features of the Ganga plains include levees, abandoned golf courses, and distinct regions such as Bhabar, Tarai, Bhangar, and Khadar plains.
- The constant shifting of river courses makes the region prone to periodic floods, with the Kosi River earning the nickname “Sorrow of Bihar.”
- This fertile expanse is home to the northern states of Haryana, Delhi, Uttar Pradesh, Bihar, a part of Jharkhand, and West Bengal.
- The Ganga-Brahmaputra delta, recognized as the largest delta globally, encompasses the tidal woods of the Sunderbans, hosting the world’s largest mangrove swamp.
- The delta’s unique ecosystem supports diverse wildlife, including crocodiles and the Royal Tiger.
- Located in northwest Uttar Pradesh, the upper Ganges alluvial plain houses a low-lying alluvial tract known as Rohilkhand.
- Positioned between the Avadh Plain and the Ganga River, it spans from the west to the east.
- Mentioned as Madhyadesh in the Mahabharata, Rohilkhand derives its name from the Rohilla tribe.
- The region is associated with the Pathan highlanders, specifically from the Yusufzai tribe, who were recognized as Rohillas.
- Positioned in the central part of Uttar Pradesh, it lies between Purvanchal in the east and Rohilkhand in the west.
- Historically known as India’s granary, this region is famous for its unique cultures and cuisines.
- Notable cities within this area include Kanpur, Rae Bareilly, and Faizabad.
- The Rarh region is situated between the Chota Nagpur Plateau in the west and the ever-changing main flow of the Ganges River in the east.
- The Rarh lowlands, located to the west of Bhagirathi-Hooghly and south of the Ganges River, are characterized by alluvial plains formed by deposits over time.
- The primary river in this region is the Damodar, and the elevation ranges from 75 to 150 meters.
- Known for its heavy industrialization, the area was previously notorious for severe floods.
- The Chhattisgarh plain is the sole deserving plain in the peninsular plateau, shaped like a saucer and drained by the upper Mahanadi.
- Situated between the Maikala Range and the Odisha hills, it is enclosed by the Chota Nagpur plateau to the north, the Raipur Upland to the east, the Bastar plateau to the southeast, and the Maikala Range to the west.
- Originally governed by the Haithaivanshi Rajputs, the region derived its name, Chhattisgarh, from their 36 forts.
- The basin consists of shales and limestone arranged in nearly horizontal strata, making it known as India’s “rice bowl.”
- Abundant coal reserves, along with significant amounts of iron ore, bauxite, manganese, and commercial clays, have contributed to the region’s development.
- The plain’s elevation varies from 250 meters in the east to 330 meters in the west.
- Key commercial hubs in the area include Bhilai, Bilaspur, Raipur, Raigarh, and Durg, while emerging urban areas include Rajgarh, Korba, and Nandgaon.
Northern Plains of India Physiographic Divisions
- The Bhabar is a narrow band extending 8 to 10 km parallel to the Shiwalik foothills.
- Streams and rivers originating from the mountains often vanish in this region, leaving behind substantial rock and boulder deposits.
- The area is characterized by large trees with deep roots, making it unsuitable for cultivation.
- The region provides building materials such as boulders.
- Footloose businesses in the area have recently received encouragement and support.
- South of Bhabar, the Terai is a marshy tract that comes into view.
- The abundant natural vegetation in this region sustains a diverse range of wildlife.
- Unfortunately, in the Indian state of Uttar Pradesh, forests in the Terai are often cleared to make room for the cultivation of crops such as wheat, rice, and sugarcane.
- Represents ancient uplands formed by alluvium deposits.
- The calcium-rich, dark-colored alluvium in this region is referred to as kankar.
- Bhangar’s soil is predominantly clay, but loam and sandy loam can be occasionally found.
- Dry areas may exhibit saline and alkaline efflorescences known as Reh.
- When a river is termed Khadar, its younger floodplain alluvium is characterized by a light color.
- This type of alluvium is deficient in calcareous materials.
- This area serves as an extension of the Khadar Plains.
- Uplands in this region are known as Chars, while the marshy terrain is referred to as Bils.
Northern Plains of India Regional Division
- This region, situated to the west of the Aravalis, encompasses Marusthali and the Rajasthan Bagar areas.
- The area features brackish lakes, a result of past marine submergence, with Sambhar being a notable example.
- Despite having several inland drainage systems, only the Luni River reaches the ocean.
- The Luni River, initially sweet in the upper areas, turns salty in the lower regions.
- Dunes and sandy terrain characterize the landscape of this region.
- The Bagar district is located 25 cm Isohyet away from this area.
- Bagar, a fertile semi-arid region, is drained by the Luni River in the south.
Punjab Haryana plain
- The Punjab Plain is a vast alluvial plain situated in Eastern Pakistan and Northwestern India, covering the Pakistani province of Punjab and the Indian states of Punjab and Haryana, along with parts of Rajasthan.
- Geographically, the plain is approximately 200–300 meters above mean sea level.
- The region is extensively used for cultivating cereals and Wheat.
- It constitutes the western segment of the Indo-Gangetic Plain, formed by the Indus River and its tributaries – the Jhelum, Chenab, Ravi, Beas, and Sutlej.
- The area between two rivers, known as Doab, consists of land formed by alluvium.
- Bhangar refers to flood plains created by the deposition of older alluvium.
- Bet indicates flood plains formed through the repeated deposition of new alluvium during each flood.
- These plains fall within the category of plain biomes.
- The northern half of the region has experienced notable erosion, primarily due to small streams called Chos.
Northern Plains of India Formation
- The northern part of the Indian Peninsula sank when the Himalayas rose in the Tethys Sea.
- Sediments from rivers flowing from the southern peninsula and the northern mountains gradually filled this sizable basin.
- The extensive alluvial deposits in this basin played a crucial role in shaping India’s northern plains.
