Peters, R.B.M. (author)This study investigates the stability of rocks in breakwater toes. Previous studies have coupled the toe stability directly to the wave height, which is not physically accurate. In this study the local hydraulic conditions at the point of incipient motion are considered. First the forces acting on a single stone are identified. Thereafter the...master thesis 2014

Attema, Y.H. (author)The interaction between vegetation and the morphodynamics is considered to be an important process in salt marsh formation and succession. Therefore, the contribution of vegetation modelling on the long-term morphological development of salt marshes is assessed by implementing a vegetation growth model in the morphodynamic modelling software...master thesis 2014

Op het Veld, R.H.T.H. (author)FLNG cooling water outfalls can be characterized as high momentum buoyant jets, relatively close to the surface. The buoyant jet trajectories, spreading rates and surface distribution very much depend on the jet outflow characteristics. A study with the CFD software OpenFOAM has been carried out into the mixing and transport processes of buoyant...master thesis 2014

Van Geffen, C.A. (author)Glacier surge behaviour is characterized by multiyear, quasi-periodic changes in glacier geometry and ice flow. Various attempts have been done on modelling glacier surge behaviour. The focus of this research will be on land-terminating, hard-bedded, temperate glaciers (LHT-glaciers). Whereas the drainage system at the base of the glacier is...master thesis 2014

Lee, E.K.C. (author)Een van de belangrijkste aspecten bij het ontwerp van een nieuwe binnenhaven of waterweg is de toegankelijkheid voor de scheepvaart. Tot medio de jaren 90 toen de Richtlijnen Vaarwegen werden gepubliceerd werd ontworpen op basis van het oordeel van ervaren nautici die zich aan de hand van bezoek, onderzoek van de stroming een beeld van de...master thesis 2014

Briele, A.C. (author)Permeable wooden pile groins have a long tradition as being part of the coastal protection in the Netherlands, as well as in Germany and the United Kingdom. They are built to protect beaches from eroding by reducing the current velocity along the beach and thus its ability to transport beach material. This type of groin is most popular among the...master thesis 2014

Siverd, C.G. (author)Hurricane Sandy made landfall in Atlantic City, New Jersey, United States (U.S.) October 29, 2012 as a post-tropical cyclone. With a wind field of approximately 1000 mi (1600 km) and a near 90 degree landfall angle with the coast, the storm generated an 11.6 ft (3.52 m) storm tide above mean sea level (MSL) at the Battery, New York City, and...master thesis 2014

Smulders, J. (author)The devastation caused by Hurricane Ike in the Galveston Bay area (Texas, United States of America) proved the necessity of an improved water defense. Multiple flood risk reduction studies were undertaken. The Texas A&M University of Galveston proposed the Ike Dike, a fortification of the coastal spine to prevent a storm surge from entering the...master thesis 2014

Woudstra, S.D. (author)Introduction In navigation locks levelling is executed under free flow. The net flow from the upper section into the lower section of the waterway is considered as a water loss. An innovative water saving concept is an IRS Lock. IRS stands for inflatable rubber structure. The concept consists of an air filled IRS applied in a lock chamber. In...master thesis 2014

Lievens, R.A. (author)Marine contractors deal with processes that are understood qualitatively but are hard to quantify. The amount of data available for these processes is ever growing, and so too the intrinsic value that lies within this data. Several data driven model approaches can be used to analyse this process data, one being a Bayesian Network (BN) approach....master thesis 2014

Arailopoulos, I. (author)Depth-averaged morphological computations using Delft3D tend to produce ‘strange’, results for river bends when the sediment transport formulas of Van Rijn are used. Even pools in inner bend regions and bars in outer bend regions can result from the model. The objective of the present thesis is to identify the cause of the problem and propose...master thesis 2014

Curto, V. (author)The morphological impact on nourishments of conditions with high oblique wave incidence has been investigated in literature using either a one-line approach or quasy-2D models. These models predict downdrift nourishment migration and the generation of alongshore sand waves for persistent conditions with high oblique wave incidence. However,...master thesis 2014

Van der Valk, K. (author)In December 2002 the highly innovative inflatable storm surge barrier near Kampen in the Netherlands was finished. This Ramspol barrier (named after the small villages next to it) has to protect the area surrounding the "Zwarte Meer" during north-western storms. These storms result in water setup that can cause severe problems for the very low...master thesis 2014

Van Mierlo, F.A.J.M. (author)Wave climates in ports can determine the efficiency of port operations to a large extent, so good predictions of them are important. This thesis therefore focusses on the modelling of wave penetration in ports, using several numerical models as well as a physical model. The goal is to compare numerical wave models for the use of wave penetration...master thesis 2014

Van Loon, P.S.P. (author)During this research a method is developed for finding the cost optimal design of a sea dike when a probabilistic method is being applied and flexibility is allowed in the distribution of the total failure probability over the various failure mechanisms. A probabilistic model has been set up to calculate the cost optimal design for a sea dike...master thesis 2014

Nederhoff, C.M. (author)Many of the most densely populated areas are located near the coast. Climate change and population growth put more and more pressure on these coastal areas. As free space is becoming sparse, coastal disaster risk reduction plans need to be spatially efficient. In this thesis the sandy coast with hard structures, such as buildings or dune...master thesis 2014

Ni, Y. (author)Vegetation in coastal areas plays an important role in its environment. In addition, vegetation can also be utilized for coastal protection. Incoming wave energy could be effectively attenuated by the upstanding vegetation plants. The reduced wave energy results in stabilized seabed and harmonious environment in coastal zones. Nowadays, an...master thesis 2014

Van Berchum, E.C. (author)The current Dutch electricity market is changing rapidly. New energy agreements demand 40% of Dutch electricity to be produced by renewable sources. This will complicate the link between supply and demand. Where demand used to be the only unknown, also a large part of the electricity supply will become less certain. It is necessary to be able to...master thesis 2014

Dijkstra, Y.M. (author)Numerical modelling for environmental flow applications, such as for rivers, lakes, estuaries and coastal flows, faces a trade-off between the numerical accuracy and the required computation time. This trade-off results in grids which typically contain 10 to 100 layers in the vertical direction. Such a grid resolution poses severe limitations to...master thesis 2014
