Backwater production arrangement for cargo ship, has resistance bodies arranged next to each other with mutual distance transverse to direction of flow of water to obtain sufficient-driving depth for ships during small flow of water

摘要

The arrangement has resistance bodies (2) arranged next to each other with mutual distance transverse to a direction of flow of water in order to obtain a sufficient-driving depth for ships during small flow of water. The resistance bodies are designed in cuboid shape. The resistance bodies are attached to a concreted tunnel (5), which responds to a river bed, where an upper edge of the tunnel is flushed with the river bed.
