Posidonia oceanica is a flexible subaquatic seagrass species that forms extensive meadows across the Mediterranean Sea. These are considered one of the most valuable ecosystems on Earth. This MSc. thesis examines the role of P. oceanica in protecting the coast from storm impacts. Prior studies are based on flume experiments that focused, almost...

A group of islands will be constructed in the lake Markermeer to act as nature reserve for birds, called the Marker Wadden. These islands will be constructed out of soft clay, dredged from the bottom of the lake. Building with soft cohesive soils, also referred to as mud, is still a largely unknown territory. Traditionally, sand is used for land...

Postma, M.G. (author)
This study describes the stability of rock on a mild slope (e.g. milder than 1:6) under wave loading. This is done because an increasing number of situations occur where mild foreshores are protected from the wave and currents. The empirical stability formula, designed by VAN DER MEER [1988], is not valid for these kind of slopes. Nonetheless,...

This thesis investigates the origin of observed current velocities at the Gemini offshore wind farm in 2015. Currents have been measured of 1.2 m/s while, based upon tidal and storm predictions, currents of only 0.7 m/s were expected. The aim of this research is to gain insight into the origin of these higher currents, taking into account the...

Aquatic vegetation attenuates local currents, dampens wave energy and promotes sedimentation. Its function as shoreline defence has gained strong interest in the recent years, since it may offer sustainable and cost-effective solutions to coastal protection problems. Predictions of wave dissipation by macrophytes require understanding of the...

The objective of this study is to identify the mechanisms that drive the morphodynamic behaviour of the sediment disposals in the subtidal zone north of the intertidal shoal Walsoorden. The morphological development of the sediment in the subtidal zone near this shoal has been monitored and measured. The gathered bathymetric data show that one...

Low-lying tropical islands are highly vulnerable to the effects of sea-level rise and climate change. Most pressing is the threat posed to their fresh water supplies by wave-induced flooding. This thesis attempts to generalize previous site-specific studies of flooding on coral atolls and apply it in a framework that can be used for early...

Fixed steel structures in the North Sea that are approaching end of life are increasing in mass and dimensions, this imposes challenges on the current decommissioning strategies. The main challenges arise during removal of the barge-launched substructures. In contrast to the topsides of these large structures the substructures cannot be easily...

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...

In dit onderzoek is aandacht besteed aan de gravitatie circulatie in de Waddenzee. Daarbij is de vraag of dit een rol kan spelen bij sedimenttransport. De gravitatie circulatie is een stroming die bovenin de waterkolom een andere stromingsrichting kent dan onderin en ontstaat doordat het water niet een uniforme dichtheid kent in het bekken....

In this study, a numerical model (XBeach-vegetation) and statistical Bayesian Network (Netica) was developed for the simulation and quantification of wave attenuation for various combinations of global salt marsh characteristics and extreme hydraulic conditions. The purpose of this modeling effort was to test the ability of the numerical model...

A survey dataset taken at the Sand Engine mega-nourishment on the southwest coast of Holland was analyzed in an attempt to locate beach scarps and characterize their development. A beach scarp is defined as a vertical discontinuity in the upper foreshore slope generated through the removal of sediment by natural processes. More specifically,...

The determination of wave penetration in ports is of great importance for the design of coastal structures and for the efficiency of port operations. Nowadays, coastal engineers can make use of numerical models for the assessment of wave climates in ports. Various numerical models exist, including the phase resolving models SWASH (TU Delft) and...

River floods are considered one of the most important natural disasters and causes huge damages every year, both in economic consequences and fatalities. Out of historical perspectives, human settlements are located in fertile and economic attractive delta regions. Deltas tend to be constantly changing nodes of economic and urban growth leading...

This thesis investigates the governing generating mechanisms, shoaling and reflection behaviour of infra-gravity waves on a mild-sloping, macro-tidal, rocky shore platform. The methods comprise among others, field data analysis of the Lilstock platform, numerical modelling using a calibrated XBeach model and a cross-correlation analysis to...

All over the world rubble mound breakwaters are built to protect harbours, shorelines, and other vulnerable coastal areas against wave action and currents. Most of the designs for these structures use so called deterministic or semi-probabilistic design methods (level I). With these methods insight in the uncertainties, and consequently the...

Om erosie en ontgronding in rivieren te voorkomen kan bodembescherming worden toegepast. Voor stenen als bodembescherming zijn er al twee verbanden bekend tussen de stroomsnelheid waarbij de stenen instabiel worden, ofwel de kritieke stroomsnelheid, en de diameter. Deze twee verbanden zijn door de onderzoekers Izbash en Shields samengesteld....

The subject of this master thesis is introduced by the lack of regulations for the design of flexible dolphins. Currently, the design of flexible dolphins is based on the Eurocode, which does not cover all aspects which are of importance in dolphin design. Consequently, different countries and associations developed their own guidelines, which...
