Eastern Scheldt Inlet Morphodynamics

In the south-western part of the Netherlands, the system of estuaries, tidal basins and islands called the Delta, has been shaped and studied by humans for centuries. By far the largest event that determined its current configuration was the storm surge that occurred in 1953. This giant flooding gave rise to one of the largest engineering...

Zanddiodes voor Delfland: Onderzoek naar de invloed van drijvende Offshore golfbrekers op de Delflandse kust

Onderzoek naar de invloed van drijvende golfbrekers op de kust van Delfland. Om de werking te zien van het zanddiode-principe in te zien, is zowel voor het langstransport als het dwarstransport, een mathematisch model toegepast op de Delflandse kust. Uit de berekeningen van het langstransport kwam naar voren, dat het mogelijk was om het netto...

Morphodynamic computations under tidal conditions: A Survey of Simplified Solution Techniques

In this report a model has been derived to simulate morphological behaviour under tidal conditions. The model is based on the set of equations of motion and mass-balance for both water and sediment. The study focused on the underlying assumption that the kinematic response of the water movement on the bottom variation is much stronger than the...

Een model voor de benadering van het jaarlijks langstransport

Bij het doen van voorspellingen op lange termijn met morfologische modellen heeft men te maken met sterk variërende randvoorwaarden (b.v. golfhoogte, getij stroming). Als men bijvoorbeeld het jaarlijkse sedimenttransport in een gebied langs de kust wil bepalen moeten eigenlijk al deze variaties van de randvoorwaarden, in de berekeningen worden...

Sand Waves along the Dutch Coast

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 realization and function of the northern basin of the Delta project

Translation of several articles pubished earlier in "Driemaandelijks bericht Deltawerken"on the works in the Haringvliet and Volkerak, as well as the watermanagement in the area after execution of the works. Design of the discharge sluices in the Haringvliet. Estimation of the morphological effects of the works in the coastal area in front of...

Littoral processes and the development of shorelines

Basic principles bearing on the nature of beaches and processes that act to modify them are considered in the light of present coastal development demands. A working hypothesis is developed that applies the principle of the conservation of mass to the mechanics of granular- fluid media. This hypothesis appears to have general application to sand...

Nearshore sediment movement - Central California coast

An 80- mile reach of the central California coast, extending from the mouth of the Russian River in the north to Half Moon Bay in the south, was studied for the characteristics of sediment movement in the nearshore zone. From the results of a large number of beach and offshore sediment samples and other information, several techniques were...

Coastal Engineering (Proceedings of the 1st ICCE, International Conference on Coastal Engineering)

The Conference on Coastal Engineering at Long Beach was conceived originally as a local meeting of engineers and scientists interested in shoreline problems and was sponsored by the University of California. It early became evident that there was widespread interest in the subject and that the program should be planned on a more ambitious scale....
