In one of the most recent studies for AGPL, Hydronamic studied the influence of works in the outer bar on the salinity-distribution in the upstream section of the estuary. The main conclusion from this study was that current-patterns, tidal prism, etc. in the inner estuary are :fully determined by ,the geometry of the Corredor, and that...

The erosion of a nourished beach may be conveniently described as the sum of the linear coastal retreat and a surcharge which decreases exponentially in time. Application of this model to data from eight nourishment projects in north-western Europe has shown on average only 52% of nourished volume becomes a permanent part of the coastal volume....

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...

Norman Hells is situated on the north bank of the Mackenzie River, 145 km south of the Arctic Circle. The use of a pool-wide water flood system for secondary recovery and the features of the oil-bearing structure require six man-made platforms to provide vertical access to the portion of the oil pool that 1 ies beneath the Mackenzie River (60%)....

Ten behoeve van een optimale keuze van een beheersstrategie voor de stormvloedkering is het nodig inzicht te hebben in het faalgedrag van glooiingen langs de Oosterscheldedijken. Hieroe zijn o.a. proeven gedaan in de Deltagoot van het WL. Deze nota analyseert de proefresultaten en vertaalt e.e.a. naar de aanwezige glooiingen langs de...

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...
