Flood plains (Vgff)

Definition
The position occupied by the water surface of a stream during a particular flood. Also, loosely, the elevation of the water surface at various points along the stream during a particular flood. Also, any plain which borders a stream and is covered by its waters in time of flood. Topographic area adjoining a channel that is covered by flood flows, as well as those areas where the path of the next flood flow is unpredictable, such as a debris cone, alluvial fan or braided channel. A nearly flat, alluvial lowland bordering a stream and commonly formed by stream processes, that is subject to inundation by floods. (Source: AASHTO Glossary)
