A thin, discontinuous layer of alluvium often covers this gently sloping bedrock surface. This type of slip-off slope is formed by the contemporaneous migration

as the meander necks are narrowed and eventually cut through by the river. Because they are low-lying, slip-off slopes are easily inundated during high water events, contributing to floodplain evolution in the middle and lower courses of a river.
