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...

In coastal regions where the land is sensitive to erosion, but also for harbours and ports, numerous types of defensive structures have been developed to protect it from the effects of incident waves. More recently breakwaters have been constructed which combine the stability characteristics of a conventional two-layered uniform sloped...

One of the most basic types of breakwaters is the rubble mound breakwater which in essence is a heap of stones consisting of a core of fine material covered by an armour layer of big rock or concrete elements. Mostly unreinforced, these concrete elements exist in different sizes and geometries varying from massive concrete cubes to more...

At breakwater and seawall projects at Port St Francis and Scarborough breakage of single layer interlocking armour units was observed. It is generally assumed that breakage of single layer armour units has a significant negative effect on the hydraulic stability of a rubble mound breakwater. The significant decrease of interlocking capacity and...

Thesis study into an alternative design for breakwaters made of granular materials like sand and quarry stone. In this design, the breakwater is constructed of a sand core and a layer of large stones directly on top of it, without the traditional filter layers in-between. The single layer of stones serves as one open filter layer that has to...

Master project report. Havana is protected from the sea’s severity by a seawall which is called the Malecón. The study area of this report is section 4 of the Malecón which more or less matches the coast of the district ‘Centro Habana’. Since the construction of the Malecón the hinterland has frequently been flooded due to storms and hurricanes...

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...

Door de jaren heen is er veel onderzoek gedaan naar golfbrekers en de stabiliteit van de 'armour layer'. Hieruit is gebleken dat de plaatsingsdichtheid van de 'armour layer' elementen een belangrijke parameter is. De doelstelling van dit onderzoek is om inzicht te verkrijgen in de invloed van de plaatsingsdichtheid op de stabiliteit van kubussen...

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...

Breakwaters can be divided into two maintypes: the classic (rubblemound) type breakwater and the vertical (caisson) type breakwater. In general it is assumed that vertical type breakwaters are more economic than classic type breakwaters, due to the quadratic increase of volume of material needed for the classic type breakwater as a function of...

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...

Although a lot is known nowadays about the run-up on smooth and impermeable slopes as well as the run-up on slopes covered with a rock armour layer, the physical properties of the armour layer of a rubble mound breakwater are not incorporated in the relations describing the run-up on a breakwater’s slope. The roughness of a slope and its...

In een gebied als Nederland met een relatiefflauw oplopende kust, heeft de conventionele stortstenen golfbreker in het verleden de voorkeur gekregen boven andere typen golfbrekers. Binnen de brekerzone wordt de golfhoogte begrensd door de waterdiepte, wat de keuze ten aanzien van de conventioneIe stortstenen golfbreker bevestigt aangezien de...

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...

Een teenconstructie van een golfbreker is het deel van een golfbreker dat zich aan de onderzijde van het golfbrekertalud bevindt. Een teenconstructie geeft steun aan het voortalud van de golfbreker en voorkomt, samen met andere golfbrekeronderdelen, het wegspoelen van constructiemateriaal en ondergrond vanonder een golfbreker. Bij het...

This study comprises the design of the reconstruction of the main breakwater of the Tripoli Harbour in Libya. Tripoli harbour is one of the oldest harbours of North Africa situated on the Southern coast of Mediterranean Sea. The harbour as it existed in 1972 was built at the beginning of this century and was protected by two main breakwaters....

Recently, interest in vertical breakwaters has grown. The development of ports from natural small harbours to artificial large harbours facing the outer sea has demanded the construction of breakwaters in rougher seas. The vertical breakwater could play a role of importance in this development. To obtain general guidelines for the design of...

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...
