A floodplain is a flat area of land bordering a river that is subjected to periodic flooding. It is made up of silts and sands which have been deposited oever many years by the river.
When the river floods over the surrounding land it loses energy and deposits its suspended load. Regular flooding results in the building up of layers of nutrient which forms a flat and fertile floodplains.
Levees
A raised river bank building up by deposition of the river during flooding period.
When the river water burst its bank, the water loses its energy and therefore deposit occurs. The heaviest materials are deposited first as these required most energy to be transported and therefore build up around the sides of the river forming raised banks known as levees.

Hey Frank I think you could have elaborated more on which part of the river floodplains are formed at. Like for example they are usually located at the lower course of the river, but overall I think you have managed to sum up most of the necessary stuff on floodplains and levees into a simple and easily understandable method.
