Bangar/Bangad/Bhangar (Hindi: बांगर) areas are beyond the floodplains, [2] that lie more upland, and compared to Khadar it consists of older alluvial soil which is higher in sandy loam content. [4] Bangar areas are less prone to flooding but are usually more sandy and less fertile as well. [5] [6]
The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. [1] [7] [8] However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690.
Soil deposit Description Image Alluvial soil Alluvial soil have been deposited by the Indus, the Ganges, and the Brahmaputra rivers. The entire northern plains (including parts of Arunachal Pradesh, Assam, Bihar (Almost entirely), Chandigarh, Delhi (almost entirely), Haryana, Himachal Pradesh, Madhya Pradesh, Punjab, Rajasthan, Uttarakhand, Uttar Pradesh, and West Bengal) are made of alluvial ...
Old alluvium is found rather away from river courses, especially on uplands of the plain where silting is a rare phenomenon. [8] A large number of small and usually seasonal rivers flow through the Terai, most of which originate in the Sivalik Hills. The soil in the Terai is alluvial and fine to medium textured.
Kankar or (kunkur) is a sedimentological term derived from Hindi (and ultimately Sanskrit) which is occasionally applied in both India [1] and the United States to detrital or residual rolled, often nodular calcium carbonate formed in soils of semi-arid regions. [2] It is used in the making of lime and of roads. [3]
The region is home to many major cities and nearly one-seventh of the world's population. As the region was formed by the deposits of the three major rivers–Indus, Ganges and Brahmaputra, the plains consists of the world's largest expanse of uninterrupted alluvium. Due to its rich water resources, it is one of the world's most densely ...
Areas where more particles are dropped are called alluvial or flood plains, and the dropped particles are called alluvium. Even small streams make alluvial deposits, but it is in floodplains and deltas of large rivers that large, geologically-significant alluvial deposits are found. The amount of matter carried by a large river is enormous.
alluvial fan A fan-shaped deposit formed where a fast flowing stream flattens, slows, and spreads typically at the exit of a canyon onto a flatter plain. alluvium Soil or sediments deposited by a river or other running water. amber Fossilized resin or tree sap that is appreciated for its vivid colour, usually reddish-orange to gold or yellow ...
