Gijón, A. (author)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...master thesis 2016

van Olphen, E.J.C. (author)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...master thesis 2016

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,...master thesis 2016

Claessens, C. (author)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...master thesis 2016

Serrano Urena, A.M. (author)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...master thesis 2016

Kala, Y.M.A. (author)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...master thesis 2016

van Kooten, V. (author)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...master thesis 2016

Bartstra, T.P. (author)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...master thesis 2016

Dorrepaal, S.G. (author)The Netherlands are protected against extreme high waters from the sea by an ingenious system of barriers. One of the most famous ones is the Maeslant barrier in the New Waterway near the port of Rotterdam. This barrier however, is subject to discussion, as it might not function as intended, because of the following reasons. It has a very low...master thesis 2016

Steenbergen, C.T.J.D.M. (author)Sheet pile walls are increasingly applied in the Netherlands to reinforce dikes. Up to now it is not known what is the real strength and stiffness behaviour of this sheet pile walls and when the dike with the construction can be considered to have failed. Nowadays an elastic design is applied for reinforcements with sheet pile walls, while for...master thesis 2016

Sehrawat, N. (author)The present state-of-the-art modelling tools (such as FAST, BLADED) used for modelling an offshore wind turbine (OWT) are too detailed and computationally expensive. These tools are required only at detailed design stages of a project. For the preliminary phase, however, a much simpler (yet reliable) 3D model can improve and speedup the design...master thesis 2016

Das, N. (author)In 2002, several mooring chains of Girassol Off-loading buoy which was installed offshore Angola ruptured just after 8 months of service. A new failure mechanism called out-of plane bending(OPB) fatigue in mooring chain links was identified in addition to tension induced fatigue after a series of experiments. Currently, there are no models in...master thesis 2016

van Elsäcker, W.A. (author)Liquefaction may have large influence on performance of anchored quay walls and is important to include in seismic design. Design codes provide evaluation methods that provide hardly any insight in the actual development of excess pore pressures and the don’t consider soil structure interaction. There is a need for tools that include these...master thesis 2016

Wang, Z. (author)Shanghai, a metropolis in the east of China, is vulnerable to flooding, and numerous floods have happened along the Huangpu River which flows through the city. In order to protect the booming city and nearly 25 million civilians’ lives and properties, a quantity of flood defences have been built along the Huangpu River. Therefore, a trustworthy...master thesis 2016

Okumura, N. (author)Five years ago, the Great Eastern Japan tsunami devastated a large part of Tohoku area (Northeastern Japan), and since then, other coastal areas in Japan have feared the possibility of such a large tsunami. This challenge of reducing flood vulnerability of coastal areas due to tsunamis has been discussed with high importance amongst the...master thesis 2016

Vasarmidis, P. (author)One of the most economically and ecologically important issues related to coastal engineering is the preservation of the coastal areas. The mean to do so, is the good understanding of the sediment transport mechanisms that are involved in the transformation of coasts. In order to protect these valuable areas, man-made structures have been...master thesis 2016

Gerritse, A.R. (author)In recent years, in a number of projects gate drive mechanisms of navigation locks were checked or adapted for a longer service life, during which the reliability, safety and availability of the structure had to be guaranteed for an extended period. Several problems were encountered. When verifying the gate drive mechanism, it was found that the...master thesis 2016

Zwennis, R.M. (author)In a world with an increasing energy demand and consciousness of the long-term effects of the use of fossil fuels, offshore industries are continuously searching for new sources of energy. Marine tidal currents, which are a consequence of the gravitational forces exerted by the Moon and the rotation of the Earth, have a theoretical potential up...master thesis 2016
