A levee ( or ),[a][1]dike (American English), dyke (British English; see spelling differences), embankment, floodbank, or stop bank is a structure used to keep the course of rivers from changing and to protect against flooding of the area adjoining the river or coast. It is usually earthen and often runs parallel to the course of a river in its floodplain or along low-lying coastlines.[2]

Levees can be naturally occurring ridge structures that form next to the bank of a river or be an artificially constructed fill[3] or wall[4] that regulates water levels. However, levees can be bad for the environment.[5]Floodwalls are a more confined alternative.
