Clark Fork River along Higgins Avenue 1931
A floodplain is a generally flat area of land next to a river or stream.  A floodplain consists of the main channel of the river (floodway) and the area beyond (flood fringe).  

Floodplains are unique and provide a number of natural and beneficial functions

Riverine and shallow flooding can occur in Missoula.  Riverine flooding occurs when a channel receives too much water causing excess flow over its banks and into the adjacent floodplain.  Shallow flooding occurs when a lack of channel means water cannot drain away easily.
