The state of the coast (Toestand van de kust). Case study: North Holland

Over more than a thousand years, the Dutch coast has been eroding for large stretches. Coastal retreat puts coastal functions (e.g. safety against flooding) under pressure. Since 1990, the Dutch policy aims at preventing further retreat of the coastline, but in the meantime taking the valuable dynamical behaviour of the coast into account....

World-wide sand bypassing systems: Data report

This report was prepared in 1996/97 as background information for the assessment of bypassing systems for the Tweed River Entrance Sand Bypassing Project. The information contained within this report has been obtained from a number of sources. The authors wish to thank all those who have provided assistance. In particular, the advice and...

Design of beach replenishment

In the Netherlands much land was captured from the sea. At the same time however along the coast severe losses of land occurred. The main reasons were sea level rise and effects of decreasing tidal volumes of estuaries. Besides there were the local effects of shifting tidal channels and periodical movements of the coastline. Building of groynes,...

A new coastal defence policy for the Netherlands

Translation of two Dutch governmental reports about the decision to maintain the Dutch coastline by means of artificial beach nourishment and to maintain the coastline of 1990 (so in fact compensate all erosion by artificial beach replenishment).

Coastal Protection and Dune Management in the Netherlands

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...

Kustverdediging na 1990 (Kustnota 1990): Technisch rapport 11: Strand en duinsuppleties

In Technisch Rapport 11 (TR 11) wordt een overzicht gegeven van de strand- en duinsuppleties, welke ter compensatie van kusterosie zijn uitgevoerd. In 1988 is het "Handboek zandsuppleties" uitgegeven. Hierin is een schat van gegevens verzameld over het desbetreffende onderwerp. Dit rapport voorziet in een aanvulling op het handboek, met meer...

Trends in sand tranfer systems

The purpose of this paper is to discuss some of the factors that have been influential in the change of functional design of sand transfer systems . The more common man-made littoral barriers are presented with types of sand transfer systems employed at each type of barrier.

By-passing and backpassing with special reference to conditions in Florida

By-passing by natural action is mentioned with special reference to Florida Inlets and to some other inlets in the United States and abroad. Natural by-passing at harbors on open shores is dealt with briefly. Present status of by-passing plant operations in Florida is reviewed. Inasmuch as it is evident that by-passing plants - partly because of...
