Doets, I.J.E. (author)Controlling the distribution of water and sediment at river bifurcations is one of the main challenges in river engineering and management. This distribution affects the stability of river bifurcations as well as the distribution of flooding risk, navigability and environmental conditions. The governing factors are the hydrodynamics of the two...master thesis 2015

Bijlard, R.W. (author)There is a shift in the approach for designing coastal structures. In the past, dikes were designed on the probability of exceedance of an incoming wave during storm conditions. In the near future, the design criteria will be the probability of flooding of the hinterland. In order to determine this flooding probability, the strength of the dike...master thesis 2015

Evers, G.A. (author)A dike is designed for an extreme event which greatly exceed the situation under daily circumstances. The expected loading during such an event is, however, difficult to estimate. Inherent uncertainties in nature and epistemic uncertainties in models and statistical data impede a clear verdict about the exact loading on a dike. Consequently,...master thesis 2015

Bresser, G. (author)The Ampelmann system consists of a motion compensating Stewart platform and a telescoping connection bridge, a gangway. The gangway creates a large asymmetric load case on top of the Stewart platform. The purpose of this study is to make the A-type operable for larger gangways by investigating the possibilities to reduce the cylinder forces by...master thesis 2015

De Kort, J.G. (author)In 2011 the Sand Motor was realised at the coast of the province of South-Holland as a pilot project combining different functions such as safety, recreation and nature development, following the philosophy of Building with Nature. The idea was to create a mega nourishment that would supply the coastal system between Hook of Holland and...master thesis 2015

Kroon, M.E.N. (author), Rip, J. (author)Coastal squeeze is defined as the reduction in the space of coastal habitats to operate [1] and it is an important cause for (amongst others) coastline retreat, an increase in flood risk and salinity intrusion. Land use changes, such as deforestation and urbanization, reduce the space of natural habitats such as mangrove forests. This causes a...master thesis 2015

Mol, M. (author)In this study, an improved error metric for morphodynamic models is introduced. Current error metrics, like the classical (Root) Mean Squared Error (RMSE), assume that predictions can be properly validated against observations by regarding the point-wise difference in bed level. This analysis inherently has the problem that phase differences of...master thesis 2015

Leontaris, G. (author)During the past years a lot of attention has been drawn towards the development of renewables, due to the expected depletion of fossil fuels and political decisions. Offshore wind energy is considered as one of the most promising renewable energy sources, however the cost of offshore wind farms have not yet reached competitive levels. Hence...master thesis 2015

Carrion Aretxabala, B.I. (author)A very large storm hit the coasts of The Netherlands-and most of north-west Europe-during the evening of the 5th of December 2013. The Sinterklaas storm, as it was later known, induced extremely high water levels and substantial dune erosion all along the Dutch coastline. In this thesis the morphological impact of the Sinterklaas storm at one...master thesis 2015

Zeelenberg, W. (author)This study investigates the existence and character of tidal flow separation at the Sand Motor, a mega-scale sand nourishment at the Delfland coast. Tidal flow contracts at the tip of the Sand Motor, downstream the tip the flow diverges and flow separation could occur. In case of flow separation the diverging streamlines cannot follow the...master thesis 2015

Wijnands, R.G.M. (author)With the increase in size of offshore structures and the increase in costs related to the construction of these facilities, a necessity to optimize the construction of offshore facilities arises. An element that contributes greatly to these costs is the transportation and installation of the structures. Transportation costs are proportional to...master thesis 2015

Berkhout, B. (author)River bed degradation is sometimes counteracted with nourishment of sediment material. Numerical models — which include Hirano’s sediment continuity model for mixed-size sediment — can be used to predict the transport of different sediment fractions (the waves due to spatial variations in the grain size distribution of the bed material are here...master thesis 2015

Verduijn, M. (author)The Meuse in the Netherlands is since the 1920s dammed by 7 weirs, which are located near Borgharen, Linne, Roermond, Belfeld, Sambeek, Grave and Lith. The weirs regulate the water levels in the canal sections (=stuwpanden) to provide sufficient depth for navigation. The management of the weirs is regulated by water level measurements at...master thesis 2015

Osmanoglou, Defne (author)Flood safety in low-lying delta regions has been a challenge of all ages. Societies worldwide have been trying to protect themselves against flood hazards for centuries. Floods in vulnerable urban regions are often caused by heavy rainfall, high river flow, extreme sea levels, or combinations of those three. Currently, there is a lack of tools...master thesis 2015

Tisheh, I. (author)Future-proof design of quay walls is an interesting issue in civil Engineering, because of the dynamic environment in which quay walls are operating. Designers are confronted with time-changing requirements such as larger retaining heights and heavier loads. However, a technical and financial analysis has revealed that the design of new quay...master thesis 2015

Witteman, D. (author)Quarry rock is a frequently applied construction material in hydraulic engineering. The main reason is its unique stability capacities in environments of high hydrodynamic activity. Furthermore, quarry rock is produced and handled relatively easily and available at numerous locations across the globe. The size, or more precisely, the dimension...master thesis 2015

Koole, T. (author)This thesis describes an analysis of modern jack-up designs. Trends throughout the various designs are identified and justified. The environmental loads and dynamic response of these modern designs are analysed using the methodology as described in current guidelines. Furthermore, the water depth limit of current design philosophy is...master thesis 2015

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

Van Corven, T.A.W. (author)The lock complex at Terneuzen is the main entrance for ships coming from the Westerscheld and navigating towards the cities of Terneuzen and Ghent. The construction of a new large lock at the lock complex of Terneuzen is planned to increase its capacity. This lock will be built between the existing locks. The ground level is situated at NAP +6...master thesis 2015

Kisoensingh, J. (author)Over the last centuries, Dutch rivers such as the Rhine have been heavily trained for the purpose of the safe discharge of water, sediment and ice, and navigability. After the notorious flood events of 1993 and 1995 along the Rhine, new large-scale river works were initiated, such as the Room for the River (RfR) programme, to increase flood...master thesis 2015
