Structural vibrations are a known cause of damage to offshore structures and equipment. A Cutter Suction Dredger (CSD) is a dredge vessel known to vibrate heavily during operation. Primary cause of these vibrations is the cutting process, performed to cut and excavate soil from the seabed. A component prone to damage is the cutter ladder, a...

A shoal connecting channel connects two main channels over a shoal area. Shoal connecting channels are dynamic in their behavior and create areas alternating in height. By doing so the connecting channels make the area ecologically more valuable. Over time the dynamics of the shoal connecting channels in the Westerschelde have decreased. The...

The Oesterdam tidal flat nourishment is a hook-shaped nourishment that was constructed in November 2013 in the Kom area of the Eastern Scheldt. One of the objectives of the nourishment is to increase the design life of the Oesterdam in the face of increasing wave loads due to structural erosion of the intertidal flats. A study is conducted in...

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...

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...

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...

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...

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...

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...

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...

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 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...

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,...

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...

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...
