Abstract

A common problem for port authorities around the world is that of shoaling in harbour basins, caused by the deposition of sediments transported by flow in adjoining channels. In order for port authorities to operate efficiently the deposited sediment has to be dredged regularly. Major benefits have been achieved in reducing this sediment build-up in harbour entrances and basins by a new passive device known as a Current Deflecting Wall (CDW). The device is a full height curved wall, located at the upstream corner of a basin entrance. Currently the only way to design a CDW is by physical hydraulic model studies, which are costly and time consuming. The paper describes recent research unde
