Het doel van dit bachelor eindproject is een antwoord vinden op de vraag of het mogelijk is door middel van het IH-2VOF model resultaten gevonden in een stroomgoot te simuleren. Dit moet worden uitgezocht omdat door gebruik te maken van dit model de teen van een golfbreker beter, veiliger en eenvoudiger ontworpen kan worden. Het onderzoek...

The main goal of this study is to determe the relation between very oblique wave attack and overtopping, and to accordingly adjust the formulae for oblique wave attack. The required knowledge to be able to read and understand this report is of a Bachelor in civil engineering level. All around the world different types of structures are built to...

In Europe the interest in and the importance of vertical breakwaters is growing. A central point is the optimal geometry, e.g. the width and height of the breakwater caisson chosen such that the total costs over the lifetime of the structure are minimized. Probabilistic design tools provide several methods to determine the probability of failure...

The first one who studied the problem of armour layer stability was Iribarren (1938). Iribarren derived stability criteria that were based on the acting physical processes on the slope of a structure. In the stability criteria of Iribarren only the influence of a few structural and hydraulic parameters were taken into account. In 1988 Van der...

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...

Onderzoek naar de inzet van materieel voor het transport van stenen over water, ten behoeve van de bouw van een golfbreker. Vanuit de praktijk (Boskalis) is de vraag gekomen om het bakkentransportproces, zoals dat plaatsvindt bij de bouw van offshore golfbrekers, nader te bestuderen. De reden daarvan is, dat de berekende productie met behulp van...

The dimensions of single layer concrete armour units (interlocking armour units) are calculated with a similar stability relation as the stability relation for quarry stone. In these design formulas an 'average/significant' wave load is used (Hs). Since quarry stone gains its stability only from gravity, this type of armour unit is constructed...

Nowadays the most important sectors in the strategy for the future of the port of Rotterdam are container handling, chemicals and distribution. To offer these sectors the opportunity to grow and renew, space is needed. By means of the construction of Maasvlakte II this space can be given. This land reclamation is planned to be located in the...

The overtopping empirical formulas calculate the discharge only at the top of the crest of a coastal protection structure. On the other hand, the tolerable overtopping discharges are defined at certain points behind the crest where the total overtopping is reduced. The scope of this thesis is to find an empirical formula to describe the...

Currently, sand retaining rubble mound structures are often constructed with geotextiles, lining the interface between the core material and the sandfill. These geotextiles are placed to make sure the sand from the sandfill is not flushed out through the core by incoming hydraulic forces from the surrounding water. It is proposed that...

The Van der Meer formula for amour stability takes the Iribarren number, number of waves and damage level into account. It also contains a factor P which describes the “notional permeability” of the breakwater. This factor is based on the fact that a more permeable structure dissipates more energy and hence requires less heavy armouring. Its...

In this MSc thesis it is investigated how the first version of concrete armour unit Xbloc+, Xbloc+ v1, acquires its stability. The stability mechanisms are investigated by conducting two type of physical model tests. First, 23 dry pull-out tests are done to obtain insights into the aspects and mechanisms that influence the...

This report presents the results of an Additional MSc Thesis as part of the Master Programme of Hydraulic Engineering from the Delft University of Technology Civil Engineering and Geosciences Faculty. The objective of this additional graduation work is to provide a better insight on economical optimization of breakwaters. Information about the...

The XblocPlus is a new type of single layer armour unit for breakwaters. The key difference between earlier single layer armour units is that the unit is not only placed in a regular grid, but also with a regular orientation. The main benefit of this is that it can directly be seen whether the unit is placed correctly. Additionally,...

The need for coastal structures, such as breakwaters, at great water depths is rapidly increasing as a result ofthe increasing draught of large vessels and off-shore land reclamations which can, for instance, be used for the benefit of the expansion of harbours and related industrial activities. In water depths greater than approximately 10 m...

Along the northern coast of Morocco order has been given for the construction of a large transshipment port in the Mediterranean Sea, at a designated project location around the city of Nador. On this green-field coastal stretch a new transhipment port will have to be developed for various types of cargo. Throughputs of the terminals will have...

A major part of the breakwaters constructed in the world are the so-called conventional rouble mound breakwaters, which consist of a core, a filter layer and a heavy armour layer. An alternative to the conventional rouble mound breakwater is a berm breakwater. Berm breakwaters have mainly developed in two directions over the last couple of...

Breakwaters are used for reducing wave height in harbours or divert sediment. One of the types of breakwaters is the rubble mound breakwater. These structures are constructed with smaller quarry rock as core and larger quarry rock as outer layer. For economical reasons, the design allows some damage to the armour layer. The amount of damage is...

Dit verslag geeft een beschrijving van een onderzoek naar de golfbelasting van kruinmuren boven op breukstenen golfbrekers. Een kruinmuur is een betonnen element dat boven op een golfbreker geplaatst wordt. De voornaamste functie is het terugbrengen van de overslag zonder toepassing van zeer veel stortsteen en toplaagelementen. In dit onderzoek...
