A floodplain is the land that is covered by water when a river overflows it's banks. When this happens, silt and clay are deposited over time and the land on either side of the river flattens out. Any depressions in the land will hold water when the river level returns to normal after flooding and therefore more clay and silt will be deposited there filling it up.
