Floodway delineation is the process by which an area is marked for use as a floodway. The Federal Emergency Management Agency (FEMA) defines a floodway as follows:
A "Regulatory Floodway" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height.[1]
