Floodplain A floodplain or flood plain is an area of land adjacent to a stream or river that stretches from the banks of its channel to the base of the enclosing valley walls and experiences flooding during periods of high discharge.[1] The soils usually consist of levees, silts, and sands deposited during floods.

Major soil deposits of India These soils are formed by the sediments brought down by the rivers. They are also rich in chemical ingredients. The rivers deposit very fine particles of soil called alluvium in their plains during their long course of journey. Alluvial soil is also known as riverine soil because it is mainly found in the river basin. Desert soils Edit These soils are found in Thar desert in the Indian state of Rajasthan. This soil is formed from arid conditions with practically negligible rainfall. This type of soil is highly pervious and has a low density. It requires densification to increase its bearing capacity and shearing strength. Commonly recognised plants that grow in these soils are cacti.

- Over thousands of years, the sediments build up floodplains. Alluvial plains often form where steep mountain valley rivers gush onto more level lands, forcing the rush of heavy waters to spill over their banks and drape their sediments out like a fan. Out on the wide-open valley floors, rivers twist and turn on a constant search for passage to the sea.

Alluvium Most, if not all, alluvium is very young (Quaternary in age), and is often referred to as cover because these sediments obscure the underlying bedrock. Most sedimentary material that fills a basin (basin fill) that is not lithified is typically lumped together as alluvial.ost, if not all, alluvium is very young (Quaternary in age), and is often referred to as cover because these sediments obscure the underlying bedrock.

- An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface. They are among the flattest, smoothest and least explored regions on Earth.

- Section Summary • Sediment forms several types of deposits, such as deltas, alluvial fans, and floodplains. • A delta is a fan-shaped deposit of sediment that forms where a river meets a large body of water. • Alluvial fans can form when a river deposits sediment on land. • Flooding brings rich soil to farmland and may cause a stream to change course. • Flooding can also lead to property damage and death.

Usage notes The noun is normally used in the plural by engineers who recover valuable minerals from these layers.

Floodplain The finer sediments transported by the floodwater, silt and clay, are deposited on the floor of the floodplain away from the levees. The general term for sediment deposited by running water is alluvium (pronounced ah-LOO-vee-em). Because floodplains are covered with alluvium, they are often called alluvial plains.

FLOODPLAIN meaning, definition & explanation A floodplain or flood plain is an area of land adjacent to a stream or river that stretches from the banks of its channel to the base of the enclosing valley walls and experiences flooding during periods of high discharge.lood plains are made by a meander eroding sideways as it travels downstream. When a river breaks its banks and floods, it leaves behind layers of alluvium (silt). These gradually build up to create the floor of the flood plain.
