Azikci, M.A. (author)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...master thesis 2015

Piccoli, C. (author)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...master thesis 2014

van den Berg, Ileen (author)The Xbloc<sup>Plus</sup> 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,...master thesis 2018

Verpoorten, S.P.K. (author)Seaports are often protected against waves and currents by rubble mound breakwaters. At the interface between outer breakwater slope and seabed a toe structure is often build, which provides stability to the outer slope. The toe consists of a relatively small heap of rock. Since 1977 dedicated studies are made to the stability of these rock...master thesis 2015

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

Le, T.N. (author)Prototype single layer armour units on a breakwater slope are observed to break. To predict when breakage occurs, the objective of this research project is to obtain knowledge on, and measurements of the rocking behaviour and failure mode of single layer armour units. A single cube on a breakwater slope is subjected to investigations. An...master thesis 2016

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

Vervoorn, H. (author)Since the awareness that the conventional energy sources will run short, the use of various renewable energy sources has been investigated, these are solar, wind, ocean and geothennal energy. Quite some countries are interested in wave energy conversion. In several countries some full-scale wave energy converting pilot plants have been tested....master thesis 1997

Van Broekhoven, P.J.M. (author)In JUMELET [2010] a method with a physical basis (so called “Volume Exchange model”) to determine the ‘notional’ permeability coefficient P was developed. The ‘notional’ permeability coefficient was previously introduced in the stability formula of the armour layer; see VAN DER MEER [1988]. In this latter study this coefficient was empirically...master thesis 2011

Verweij, A.P. (author)Vertical breakwaters are used in the design of harbours to create a protective area. This protective area can be an approach channel or the harbour itself. Because of large new projects, such as Maasvlakte 11 in the Netherlands and the increasing sizes of ships, many harbours have to be placed in deep water. Deep water requires higher...master thesis 1997

Voortman, H.G. (author)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...master thesis 1997

Schepers, M.R. (author)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...master thesis 1998

Van de Koppel, M.A. (author)Interlocking, single layer concrete armour units are placed in a specific grid depending on the type of armour unit. Within this grid, armour units are placed in horizontal rows. The number of horizontal rows of single layer armour units on a breakwater is limited to 20. This limit is proposed in order to prevent major settlements, which might...master thesis 2012

Heuts, R.A.R. (author)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...master thesis 2010

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

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

DERMENTZOGLOU, Dimitrios (author)This work studies crownwalls with a fully curved face versus a vertical wall in non-breaking wave conditions. Its aim is to provide appropriate tools that can be used to compare the performance of the two structures in terms of loading and overtopping. To this end, small scaled experiments of the two structures are carried in a flume with a flat...master thesis 2021

Kik, R. (author)The stability formula developed by Van der Meer is used for the design of different kind of rock slopes. In the formula is among a number of other parameters also the permeability of the structure represented. A more permeable structure has the ability to dissipate more water and therefore more energy, this results into a lower required weight...master thesis 2011
