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 ]
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 ...
The difference between a flood plain and an alluvial plain is: a flood plain represents areas experiencing flooding fairly regularly in the present or recently, whereas an alluvial plain includes areas where a flood plain is now and used to be, or areas which only experience flooding a few times a century.

Exhumed river channel – Ridge of sandstone that remains when the softer flood plain mudstone is eroded away; Floodplain – Land adjacent to a water body which is flooded during periods of high water; Fluvial island – Exposed landmass within a river; Fluvial terrace – Elongated terraces that flank the sides of floodplains and river valleys
Proponents of flood geology hold to a literal reading of Genesis 6–9 and view its passages as historically accurate; they use the Bible's internal chronology to place the Genesis flood and the story of Noah's Ark within the last 5,000 years. [4] Scientific analysis has refuted the key tenets of flood geology.
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".
