Floodplains and Levees

What landforms can be created along the course of a river?

MIDDLE AND LOWER COURSE - Floodplains and Levees

Levees can be natural or manmade. They form on the edge of a river channel. When a river floods the velocity of the water flowing over the floodplains suddenly drops.  This fall in velocity means that the river has less energy, so immediately deposits its load. The river deposits the largest material first on the banks of the river, creating embankments. Over time these embankments begin to grow in size and become more stable.
