What is the floodplain of a stream?
A floodplain is the low-lying ground adjacent to a river subject to flooding. A river terrace is the bench or step that extends along the side of a valley and represents a former level of the floodplain of a stream or river.
Where is a floodplain formed?
Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Wherever the river meanders, the flowing water erodes the river bank on the outside of the meander, while sediments are simultaneously deposited in a point bar on the inside of the meander.
What is the floodplain of a stream quizlet?
What is a floodplain? The floodplain is the wide, flat area of land either side of the river in its lower course.

What is floodplain in river?
A floodplain (or floodplain) is a generally flat area of land next to a river or stream. It stretches from the banks of the river to the outer edges of the valley. A floodplain consists of two parts. The first is the main channel of the river itself, called the floodway.
How floodplain lakes are formed?
Floodplains are produced by lateral movement of a stream and by overbank deposition; therefore they are absent where downcutting is dominant. Any erosional widening of one bank is approximately equalled by deposition on the opposite side of the channel in the form of bar development along the inside of meander bends.

How does a floodplain form quizlet?
When a river floods onto the flood plain, the water slows down and deposit the eroded material that it's transporting. This builds up the floodplain. Meanders migrate across the flood plain, making it wider.

Why is it called a flood plain?
Lesson Summary. A floodplain is where a stream or river regularly overflows, whether it's over a small area or gigantic area. The river or stream often overflows seasonally, and floodplains tend to be rich agricultural areas because of the sediment that is deposited during flooding.
