A floodplain or flood plain or bottomlands [1] is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high discharge. [2] The soils usually consist of clays, silts, sands, and gravels deposited during floods. [3]
Observations made on long geologic times scales (≥10 6 annum) typically reveal much about slower, larger-magnitude geologic processes such as tectonism [5] from a regional to even global scale. Evaluation on geologically short time scales (10 3 -10 5 a ) can reveal much about the relatively shorter climatic cycles, [ 5 ] local to regional ...
Fluvial terraces are elongated terraces that flank the sides of floodplains and fluvial valleys all over the world. They consist of a relatively level strip of land, called a "tread", separated from either an adjacent floodplain, other fluvial terraces, or uplands by distinctly steeper strips of land called "risers".
An overbank is an alluvial geological deposit consisting of sediment that has been deposited on the floodplain of a river or stream by flood waters that have broken through or overtopped the banks. The sediment is carried in suspension , and because it is carried outside of the main channel , away from faster flow, the sediment is typically ...
Flood geology (also creation geology or diluvial geology) is a pseudoscientific attempt to interpret and reconcile geological features of the Earth in accordance with a literal belief in the Genesis flood narrative, the flood myth in the Hebrew Bible.
An alluvial plain is a plain (an essentially flat landform) created by the deposition of sediment over a long period by one or more rivers coming from highland regions, from which alluvial soil forms. A floodplain is part of the process, being the smaller area over which the rivers flood at a particular time. In contrast, the alluvial plain is ...

In geology, a backswamp is a type of depositional environment commonly found in a floodplain.It is where deposits of fine silts and clays settle after a flood.These deposits create a marsh-like landscape that is often poorly drained and usually lower than the rest of the floodplain.
