Embanking arrangement

Abstract

Disclosed is an embanking arrangement for separating and protecting a first water volume from a second water volume, including a barrier connected to land and having an opening, a stationary basis extending across the opening, and a mobile port arrangement including a hull delimiting an inner tank. The embanking arrangement takes closed and open states respectively, wherein the inner tank of the port arrangement is at least partly filled with water and the hull of the port arrangement is standing on the basis when the embanking arrangement is in the closed state. The port arrangement is floating in the open state. The port arrangement includes at least a first opening connecting the inner tank and the first water volume, and including a controllable valve, and a pump connected with the second water volume to transport water from the first water volume to the second water volume.
