Northern Plains - The Northern Plains of India, one of the most fertile and densely populated regions, hold significant geographical, agricultural, and cultural importance. Extending across the northern part of the Indian subcontinent, these plains are shaped by the alluvial deposits of mighty rivers like the Indus, Ganga, and Brahmaputra. This article explores the formation, divisions, characteristics, and significance of the Northern Plains.
Formation of the Northern Plains
The Northern Plains were formed through the deposition of alluvium brought down by rivers originating from the Himalayas and the Peninsular Plateau. This process occurred over millions of years, leading to the creation of one of the world's largest and most fertile alluvial plains.
Key Features
Area Covered: The plains stretch approximately 3,200 km from west to east.
Width: Varies between 150-300 km.
Depth of Alluvium: Ranges between 1,000-2,000 meters.
Rivers: The region is watered by rivers from the Indus, Ganga, and Brahmaputra river systems.
Divisions of the Northern Plains
The Northern Plains can be divided into three distinct zones based on their geographical features:
1. Bhabar
Location: Narrow belt parallel to the Shiwalik foothills.
Width: Approximately 8-10 km.Characteristics: Streams and rivers flowing from the mountains deposit heavy materials like rocks and boulders here. As a result, rivers often disappear in this zone due to the porous soil.
2. Terai
Location: South of the Bhabar belt.
Width: Approximately 10-20 km.Characteristics:
- Rivers re-emerge without forming a clearly demarcated channel.
- Known for its marshy and swampy conditions.
- Rich in natural vegetation and biodiversity.
3. Alluvial Plains
The alluvial plains are the most fertile zones and are further divided into:
Khadar:- New alluvium deposited annually by rivers.
- Extremely fertile and ideal for agriculture.
- Older alluvial deposits situated above the floodplain.
- Less fertile compared to Khadar, containing calcareous deposits called Kankar.
River Systems of the Northern Plains
1. The Indus River System
- Rivers: Indus, Jhelum, Chenab, Ravi, Beas, and Sutlej.
- Importance: Major irrigation source in the Punjab and Haryana regions.
2. The Ganga River System
- Rivers: Ganga, Yamuna, Ghaghara, Kosi, and Son.
- Importance: Forms the core of the fertile Gangetic Plains, supporting dense agriculture and population.
3. The Brahmaputra River System
- Originates in Tibet and flows through Arunachal Pradesh and Assam.
- Known for its unique riverine islands, such as the famous Majuli island.
Importance of the Northern Plains
1. Agricultural Significance
The alluvial soil of the Northern Plains supports the cultivation of crops like wheat, rice, sugarcane, and jute, making it the agricultural heartland of India.
2. Water Resources
The extensive river systems provide water for irrigation, drinking, and industrial use.
3. Population and Economy
The plains are home to a dense population and contribute significantly to India's GDP, owing to agriculture, trade, and industry.
4. Biodiversity
The Terai belt houses diverse flora and fauna, including protected areas like Jim Corbett National Park.
