A coupure is a means of closing an opening in a wall, floodwall or levee (dike). The word comes from the French verb couper which means "to cut". In historic times a coupure was a location where a breach in the city walls or the walls of a fortress was closed. In more modern times a coupure is a way of allowing traffic to pass a flood protection structure.
