(4112) Floodplain, or Flood Land
1 - The portion of the landscape inundated by a flood. The extent of the floodplain is often defined by a particular frequency flood : the 100-year floodplain is the area inundated by a flood with an average return period between events of 100 years, or an annual probability of occurrence of 0.01 (illustrated). 2 - The flood-prone areas adjacent to a river channel over which flood waters habitually and temporarily spill when river flows exceed the bank-full capacity of the river channel. Generally a 100-year return period flood level is accepted as defining the limit of a floodplain. 3 - Also see 4122.
