Verhagen, H.J. (author)
The government of The Netherlands has decided in the summer of 1990 to maintai.n the coastline at the position of 1990. This will be done mainly by artificial beach nourishment. The costs will be paid by the national government. The purpose of this coastal maintenance is to maintain a sufficient level of safety and to maintain the various...

The 350 km long Dutch coast along the North Sea is characterized by alternating coastal stretches of accretion and erosion resp. resulting in seaward and landward displacement retreats of the shoreline. Places of accretion and erosion also vary in time. Behind the dunes are low lying polders (very often with a ground level even below the low...

In the Netherlands today much attention is paid to the effect of coastal structures on the environment. In the past it was usual to quantify the effect of such a structure on its environment solely with the purpose of deciding whether that effect could imply any hazard to the structure itself (or to structures in the neighbourhood). Nowadays...

Kraus, N.C. (author)
This report consists of seven papers dealing with numerical simulation of beach change that were recently published by members of the Coastal Engineering Research Center, US Army Engineer Waterways Experiment Station, and colleagues from other organizations. The papers collectively provide an overview of the state of research and engineering...

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...

The set-up and results of a field experiment on sand-dike breach erosion are described, It is found that the breaching process for the 2.2 m high sand-dike is similar to that in Visser's (1988) laboratory experiments with a 0.6 m high sand-dike. Confrontation of Visser's (1988) breach erosion model with the field data shows reasonable agreement...

A method is presented to evaluate the safety of dunes as a sea defence. The method is based on the dune erosion profile according to VELLINGA combined with a probabilistic approach. Every dune can be tested with this method and it is possible to determine the probability of collapse of a dune whereby the polders are flooded.
