Abstract


In this paper a harbour engineering application of an operational system to forecast circulation and transport fields is presented. It deals with the functional design of a quay in the Bilbao harbour (Bay of Biscay, North-Atlantic coast of Spain). The aim is to use physical oceanography “tools” to design the optimal quay alignment according to two criteria: i) Minimize the currents in order to guarantee the vessel maneuverability and quay operability for given safety levels and ii) Maximize the water renewal capacity of the harbour inner basins (beyond the studied quay) in order to reduce the risk of water quality degradation. The methodology and the results reveal a new procedure to enhance the harbour lay-out design from an environment point of view.
