description Bengal Plain Overview
The Bengal Plain is a broad alluvial lowland in the eastern part of the Indian subcontinent, formed largely by sediments deposited by the Ganges, Brahmaputra, and Meghna river systems. It covers most of Bangladesh and extends into the Indian states of West Bengal and adjoining areas. Its fertile floodplain soils support intensive agriculture, while the low elevation, monsoon rains, river flooding, and dense settlement create recurring environmental risks.
help Bengal Plain FAQ
Where is the Bengal Plain?
The Bengal Plain is a broad alluvial lowland in the eastern Indian subcontinent. It covers most of Bangladesh and extends into West Bengal and nearby parts of India.
Which rivers formed the Bengal Plain?
The Ganges, Brahmaputra, and Meghna river systems supplied much of the sediment that formed the plain. Their channels and floodplains continue to reshape the region.
Why is the Bengal Plain so fertile?
Regular flooding deposits nutrient-rich alluvium across large parts of the lowland. This supports intensive agriculture, including rice cultivation, although floods and river erosion create serious risks.
Is the Bengal Plain the same as the Ganges Delta?
They overlap but are not identical terms. The Bengal Plain is the broader lowland, while the Ganges-Brahmaputra-Meghna Delta describes the river-built deltaic area near the Bay of Bengal.
