PORT OF LISBON IMPROVEMENT OF THE ACCESS CONDITIONS THROUGH THE TAGUS ESTUARY ENTRANCE

I.B. Mota Oliveira

Abstract


The Port of Lisbon authority is aiming at the reception of container ships of the fourth generation. For that a deeper and wider artificial channel has to be dredged through the outer bar. The set of studies undertaken (data collection, site investigations, mathematical and physical modelling) put into evidence the importance ofthe opening of a secondary bar, some 50 years ago, over the general morphological behaviour of the estuary entrance. So a recommendation has been made to close it using an artificial sand dike.
