The Administracao dos Portos do Douro e Leixoes is confronted with the fact that future expansion of the port area of Leixoes is limited by the surrounding hills and urbanization. One of the alternatives for future expansion might be the creation of port facilities in the Douro estuary, where a relatively large, flat area is available. However, the river entrance is rather unstable from a morphological point of view, so that regular dredging is required to maintain an access channel. In order to eliminate the risk of unexpected morphological changes in the Douro estuary, due to harbour works in thee Douro estuary, APDL has decided to study the morphology of the Douro bar thouroughly, and to make a design for a mathematical model to investigate the influence of harbour works in the area. The study consists of: (1) wave penetration study (2) calculation of longshore transport (3) calculation of tidal prism (4) sediment transport measurements (5) morphological evaluation (6) set-up of a mathematical model.
