Antidune

From Wikipedia, the free encyclopedia

An antidune is an upper flow regime sedimentary structure found in aquatic environments. In an antidune system, material is deposited on the lee side and eroded from the stoss side. Waves follow the curves of the antidunes, rather than being offset as in dunes.
