In het kader van het landelijk kustbeleid is een methode voor het berekenen van de kustlijn ontwikkeld (nota wba-n-90.125). De aldaar beschreven methode wordt hier toegepast voor een aantal kustvakken (Ameland, Callantsoog, Kop van Schouwen). Geconcludeerd wordt dat de gebruikte rekenmethode een redelijk stabiel beeld van de kustlijnligging geeft.

Because dunes protect a large part of The Netherlands against coastal flooding and inundation, it is vital to guarantee the strength of these natural sea defenses. Besides sea defense, dunes have other functions. Sandy shorelines and dunes are frequently eroded. A legal framework has been developed that guarantees the required safety-level of...

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....
