Use of "alluvial plain" as a general, informal term for a broad flood plain or a low-gradient delta is explicitly discouraged. The NCSS glossary instead suggests "flood plain". [1] Alluvial plains have similar traits to a river delta; however, the river delta will flow into a larger body of water. Alluvial plains generally lack this.
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.

Alluvium and adjacent constituents Alluvium deposits in the Gamtoos Valley in South Africa An alluvial plain in Red Rock Canyon State Park (California) Alluvial river deposits in the Amazon basin, near Autazes, AM, Brazil. The seasonal deposits are extremely fertile and crucial to subsistence farming in the Amazon Basin along the river banks.
A wide, flat, gently sloping plain created by the long-term deposition of alluvium from one or more rivers flowing from highland regions, and typically characterized by various fluvial landforms such as braided streams, terraces, and meanders. Alluvial plains encompass the larger area over which a river's floodplain has shifted through ...
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 old fallacy exists regarding the formation of point bars and oxbow lakes which suggests they are formed by the deposition (dropping) of a watercourse's suspended load claiming the velocity and energy of the stream decreases toward the inside of a bend.
The Chiayi–Tainan, Chianan or Jianan Plain (Chinese: 嘉南平原; pinyin: Jiānán Píngyuán), is an alluvial plain located at the central-southern region of western Taiwan. It is the largest plain of the island, [ 1 ] and lies in Tainan City and Chiayi County / Chiayi City , from which the name of the plain derived.
Veneto-Friuli foreland basin, an alluvial plain in north-eastern Italy. Developed as the result of superposition of three overlapping foreland systems which differed in age and tectonic movement direction as this plain is the foreland of three surrounding chains.
