Maasvlakte 2 is het project waarmee de haven van Rotterdam wordt uitgebreid. Het sluit direct aan op de huidige Maasvlakte. De havenbekkens van beide Maasvlaktes worden verbonden door de Yangtzehaven in westelijke richting door te steken naar Maasvlakte 2. De doorsteek bestaat uit een voorfase waarin een kanaal wordt gegraven ten behoeve van de...

Op moment van schrijven is de aanleg van Maasvlakte 2 in volle gang. Het masterplan is echter nog in ontwikkeling, maar steeds meer keuzes worden vastgelegd. Daarom moet onderzocht worden of er op Maasvlakte 2 een ruimteclaim voor een Binnenvaart Service Centrum (BSC) moet blijven staan. Een BSC is een neutrale binnenvaartterminal waar een deel...

Since the end of 2006 in the Netherlands a test is going on with a passive beach drainage system called Ecobeach. The system consists of vertical draining tubes with a length of 2.0 m called PEMs (Pressure Equalizing Modules). Under the surface level, every 100 m a row of PEMs is installed between the high and low waterline. Ecobeach is a Danish...

The goal of this master thesis is to describe the spatial distribution of the wave overtopping discharge over and behind the crest of a coastal defence structure. The influence of the most relevant parameters on this process is explored. This research has been performed by means of a physical model. The following relevant parameters were varied...

Er is onderzoek gedaan naar de technische en economische haalbaarheid van voorgespannen diepwanden. Binnen enkele randvoorwaarden, blijkt het goede mogelijkheden te geven om de zettingen van de belendingen tot een minimum te beperken.

The most densely populated and economical most valuable areas in The Netherlands lie below mean sea level. These areas are protected against the sea by a joint coastal dune system. The vital importance of this dune system is reflected in the extensive collection of Dutch legal regulations that ensure the safety level of the dunes. The assessment...

For a proposed liquefied natural gas export facility, Olokola LNG (OKLNG), located at the western limits of the Niger Delta in Nigeria a 10 km long and 17 m deep approach channel is designed for tankers to reach the terminal at the shoreline. Mud is expected to be deposited in the channel because of the persistent swell climate which mobilizes...

Groins are old and intuitive means of reducing erosion and are found along the coast worldwide, although according to CEM (Coastal Engineering Manual 2003), “they are probably the most misused and improperly designed of all coastal structures”. The original purpose of groins was to reduce local erosion, that is, to hold the width of beach in...

Two dimensional physical model tests are executed with Xbloc armour units on low crested structures to answer the objective. On the basis of findings in the literature study it can be expected that the stability of the Xbloc elements on low-crested breakwaters is a function of crest freeboard and crest width. The crest freeboard (Rc/Dn) varied...

The purpose of this thesis was to develop a preliminary concept design of a wave energy converter. The type of device designed was limited by several starting points which stipulated, among other criteria, a robust structure which can be constructed within a breakwater and can generate electricity from a fairly mild (in the order of Hs=0.5-1.5m)...

This thesis is about the influence of the specific weight on the stability of single layer interlocking armour units on rubble mound breakwaters. The hydraulic stability of the Xbloc armour unit is expressed by the stability number which is based on the assumption of dominance of lift, drag and gravity forces. If other forces have significant...

In an attempt to reduce the cost of breakwaters, several elements have been developed. Examples are Accropodes, Tetrapods and concrete cubes. Previous tests were performed with armour layers consisting of a double layer of cubes. This study is based on a single layer of cubes. The great benefit of a single layer of cubes is that it reduces the...

In numerical modelling of water movement wetting and drying is a well known problem. The governing equations are not valid in the dry part of the computational domain which may result in problems with mass conservation, negative water depths and artificially enlarged gradients. A method is proposed that allows for the surface elevation to become...

The second Delta-committee (September 2008) foresees difficulty in resolving flood safety issues for Rotterdam and Dordrecht if high river runoffs are still running through the New Waterway. A new safety issue, induced by climate changes, lies in the combination of closed sea defensives and relatively high river runoffs at the same time. A...

As waves enter the surf-zone, the wave spectra undergo drastic transformations because of depth-induced breaking and triad interactions. Any arbitrary spectrum will converge towards a smooth, universal shape in which initially higher harmonic peaks emerge that disappear as wave propagate further into the surf-zone. The current formulation of...

The elastocoast system can be used as an armour layer on revetments. The bonding system exists of a mix of crushed stones and 2-component polyurethane. This bonding system creates bonding forces between the stones and an open (porous) structure can be obtained. Elastocoast is developed by Elastogran GmbH, a BASF subsidiary. The response of an...

After a storm surge in November 2007, older storm surge deposits were discovered in the eroded dunes near Heemskerk, the Netherlands. These deposits undulate in height with a maximum elevation of over 6 m above mean sea level. Luminescence dating suggests that the layers were deposited by either the 1775 or the 1776 storm surge. The aim of this...

The Westerschelde estuary in the South-West of the Netherlands displays two meandering flood and ebb channels separated by shoals. The system of flood, ebb channel and shoal between two channel crossings form a morphological cell. The stability of the serial cell system formed by the Westerschelde is important for the navigation route to the...

Bed degradation in a number of Dutch river branches, like the Bovenrijn, can cause various problems in the near future. At low waters the navigation depth at the non-erodible layer near Emmerich can become too small. Other problems could be lower ground water levels and stability of structures in and near the river, like groynes. To diminish...

Compare the 1D spectrum computed in SWAN (Svasek, 2007) with it measured by buoy OS4 in the Oosterschelde Estuary, serious underestimation of wave energy can be found on low-frequency band. Investigation has been performed to find the possible reasons for the missing energy on low frequency part. In this study, diffraction is hypothesized as the...
