Floodplain

Gravel floodplain of a glacial river near the Snow Mountains in Alaska, 1902

Entrenched river: The Virgin River at the upper end of Zion Canyon, Zion National Park, Utah, has almost no floodplain at all.

A floodplain or flood plain is an area of land adjacent to a stream or river that stretches from the banks of its channel to the base of the enclosing valley walls and experiences flooding during periods of high discharge. It includes the floodway, which consists of the stream channel and adjacent areas that actively carry flood flows downstream, and the flood fringe, which are areas inundated by the flood, but which do not experience a strong current. In other words, a floodplain is an area near a river or a stream which floods when the water level reaches flood stage.
