Deiters, B. (author)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...master thesis 1999

Laenen, K.C.J. (author)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...master thesis 2000

De Heij, J. (author)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...master thesis 2001

Van den Bosch, A.F.M. (author)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...master thesis 2001

Garcia Beses, A.J. (author)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...master thesis 2005

Baart, S.A. (author), Van Kruchten, Y.J.G. (author), McCall, R.T. (author), Van Nieuwkoop, J.C.C. (author)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...student report 2006

Ockeloen, W.J. (author)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 thesis 2007

De Rover, R.A. (author)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...master thesis 2007

Fozein Kwanke, N.J.C. (author)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...master thesis 2007

Dijkstra, O.P.J. (author)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...master thesis 2008

Sveinbjornsson, P.I. (author)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...master thesis 2008

Van Buchem, R.V. (author)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...master thesis 2009

Schoolderman, J.E. (author)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)...master thesis 2009

Van Zwicht, B.N.M. (author)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...master thesis 2009

Van der Linde, J.P. (author)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...master thesis 2009

Kersten, M.K. (author)Albania has the following major sea ports: Durrës, Vlora, Sarandë and Shëngjin. The port of Durrës has the biggest share in the volume of import/export in Albania, nearly 75%. Due to current development rates, limited possibilities for expansion and pollution in the city because of its vicinity to the port, projects are identified to construct a...master thesis 2010

Mulders, P.H.M. (author)During the construction of breakwaters contractors often encounter undesired reshaping of exposed core material. This reshaping is comparable to the deformation process of berm breakwaters in which the outer profile reshapes into a more stable s-curve. In the case of oblique waves this deformation is enhanced by a longshore transport of stones...master thesis 2010

Afridi, Z.N. (author)The purpose of this report is to investigate the differences in overtopping characteristics over the crest of a rubble mound breakwater when the crest is made either impermeable or permeable. Among numerous characteristics that are effected by a modification in the permeability of the crest, this report looks specifically into three separate...student report 2010

Lioutas, A.C. (author)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...master thesis 2010
