The lowlands adjoining the channel of a river, stream, or watercourse, or ocean, lake, or other body of standing water, which have been or may be inundated by flood water The channel of a stream or watercourse is part of the floodplain
(a) The surface of strip of relatively smooth land adjacent to a river channel, constructed by the present river in its existing regimen and covered with water when the river overflows its banks It is built of alluvium carried by the river during floods and deposited in the sluggish water beyond the influence of the swiftest current A river has one flood plain and may have one or more terraces representing abandoned flood plains (b) Any flat or nearly flat lowland that borders a stream and that may be covered by its waters at flood stages; the land described by the perimeter of the maximum probably flood (c) The part of a lake-basic plain between the shoreline and the shore cliff, subject to submergence during a high stage of the lake
A strip of relatively level land bordering a stream or river It is built of sediment carried by the stream and dropped when the water has flooded the area It is called a water flood plain if it is overflowed in times of high water, or a fossil flood plain if it is beyond the reach of the highest flood
- The nearly level plain that borders the river and is subject to inundation from the main channel relatively frequently, usually once every two years or more frequently A flood plain is a depositional landform constructed from the river under current hydro-climatic conditions
A strip of relatively smooth land bordering a stream, built of sediment carried by the stream and dropped in the slack water beyond the influence of the swiftest current It is called a living flood plain if it is overflowed in times of highwater; but a fossil flood plain if it is beyond the reach of the highest flood (Bryan, 1922, p 88 )
The area around a body of water which may at times be under water and may at other times be dry land, depending on the level of the water in the lake, river, pond, etc
Areas of land that are subject to periodic flooding by a neighboring river, stream or other body of water Flood plains are classified according to the anticipated frequency of flooding
A flood plain is a flat area on the edge of a river, where the ground consists of soil, sand, and rock left by the river when it floods. the large area of flat land on either side of a river that is sometimes covered with water when the river becomes too full
