Floodplains and Meanders By group 3 -Amy, Edward, Komal, and Tony.

Floodplains Flood plains are made by a meander eroding sideways as it travels downstream. When a river breaks its banks and floods, it leaves behind layers of rock and mud. These build up to create the floor of the flood plain. Floodplains can support to have a good ecosystem. Historically, a lot of big towns have been built beside floodplain. There were a lot of reasons why people built a lot of cities besides the floodplain. It was because they can use a lot of fresh water, the fertility of floodplain land for farming, cheap transportation because they can use boats for transportation, and development of flat land.

Meanders The middle course or lower course flows in large bends. These bends are called meanders. A meander is a general bend in a curved watercourse. A meander is formed when a stream erodes the outer bank and widens its valley. The formation of a meander is a result of natural factors. When a meander is formed an oxbow lake is formed, an oxbow lake is a u-shaped body of water formed, when a wide meander from the main steam of a river is cut off to create a lake.
