As you know Active floodplain is an area alongside a lake, stream or other body of water that is periodically flooded, ranging from rare, severe storm events to flows experienced several times a year.

Old floodplain is opposite to active floodplain its is only flooded when there is heavy monsoon rainfall and are covered with old alluvium (alluvium deposited in the past).
