The calculations of bottom changes presented in our report "Terminal do Seixal Hydro-morphological study", February 1982 were based on a calibrated sediment transport formula. This formula was calibrated with the results of measurements made by Hydronamic in September 1981. These measurements were executed during one of the driest summers...

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,...

Sand waves, defined as longshore wave-like movements of the shoreline, measured in a horizontal plane, are described along several stretches of the shoreline of The Netherlands. They have a celerity in the order of 50-200 m/yr, a period of 50- 150 years and an amplitude of 30- 500 m. They are found along the whole Dutch shoreline. Analysis of...

The 1400 km Dutch coastline is affected by sea level rise. At this moment a legal framework is made to guarantee the safety of dikes also in future. Also a national policy id developed for compensation of all coastal erosion. Both measures should make it possible for the Netherlands to survive an increased sea-level rise,

In a densely populated country such as The Netherlands it is almost impossible to install large numbers of large windturbines on the mainland. That was the main reason to investigate the possibilities of siting the windturbines offshore on the Dutch part of the North Sea Continental Shelf, with a further advantage of a higher windfactor. The...

Because a sandy coast is a very dynamic coastline, and because stability of the coastline is vital for the safety of the Netherlands against inundation by storm surges (dunes protect the polder-area, which is situated below sea level), already in former centuries it was necessary to get some knowledge about the movements of the coastline. In the...
