Van Buchem, R.V. (author)In an attempt to reduce the cost of breakwaters, several elements have been developed. Examples are Accropodes, Tetrapods and concrete cubes. Previous tests were performed with armour layers consisting of a double layer of cubes. This study is based on a single layer of cubes. The great benefit of a single layer of cubes is that it reduces the...master thesis 2009

Daly, C.J. (author)It has been found by many researchers that low frequency (LF) waves dominate the wave energy spectrum in very shallow water. Given that many longshore and cross-shore morphological processes are located within this zone, LF waves play an important role in determining morphological change, especially dune erosion and overwash during storm events....master thesis 2009

Boshek, M.R. (author)Diffraction diagrams are frequently utilized by engineers within the feasibility and early design phases of a project. These helpful graphics, based on directional spreading and wavelength, can be used for a number of layouts and angles of incidence. In spite of the tendency to design breakwaters for the fullest dissipation of wave energy,...master thesis 2009

Kooistra, J. (author)Connected to the Pacific Ocean by the Golden Gate channel, the San Francisco Bay accommodates a widely spread field of sandwaves that show large spatial variations which are not yet fully understood. Insight into the formation of sandwaves is necessary to understand and predict the processes that control sand transport and sedimentation patterns...master thesis 2009

Sluijsmans, R.W. (author)The elastocoast system can be used as an armour layer on revetments. The bonding system exists of a mix of crushed stones and 2-component polyurethane. This bonding system creates bonding forces between the stones and an open (porous) structure can be obtained. Elastocoast is developed by Elastogran GmbH, a BASF subsidiary. The response of an...master thesis 2009

Ravenstijn, E. (author)Bed degradation in a number of Dutch river branches, like the Bovenrijn, can cause various problems in the near future. At low waters the navigation depth at the non-erodible layer near Emmerich can become too small. Other problems could be lower ground water levels and stability of structures in and near the river, like groynes. To diminish...master thesis 2009

Mahmoodian, M. (author)Marine renewable energy as a infinite source of energy can be a reliable alternative for fossil fuels particularly in the UK with high potential wave energy in the Britain marine environment. Wide variety of wave energy converters has been developed in last decades and presenting more economical and reliable technologies is also under process....master thesis 2009

Belyaev, P. (author)Thesis deals with finite element (FE) simulation of borehole jack (BHJ) tests in ice. The purpose of the thesis was to simulate elastic-plastic range shown in BHJ tests, compare measured ice stiffnesses with obtained from simulations, fit plastic range, investigate plastic properties and stress descending in surrounding ice. Eight BHJ tests...master thesis 2009

Pieterse, J.J. (author)Since the end of 2006 in the Netherlands a test is going on with a passive beach drainage system called Ecobeach. The system consists of vertical draining tubes with a length of 2.0 m called PEMs (Pressure Equalizing Modules). Under the surface level, every 100 m a row of PEMs is installed between the high and low waterline. Ecobeach is a Danish...master thesis 2009

Zimmermann, N. (author)The Westerschelde estuary in the South-West of the Netherlands displays two meandering flood and ebb channels separated by shoals. The system of flood, ebb channel and shoal between two channel crossings form a morphological cell. The stability of the serial cell system formed by the Westerschelde is important for the navigation route to the...master thesis 2009

Aziz, N.S. (author)With the instability of oil prices and the increasing of people’s awareness in environmental problems, renewable energy is the key solution of these problems. Tidal energy, with its advantages of being predictable and its high energy density, is one of the most promising renewable energy forms. Indonesia’s topographic conditions with plenty of...master thesis 2009

Schoolderman, J.E. (author)The purpose of this thesis was to develop a preliminary concept design of a wave energy converter. The type of device designed was limited by several starting points which stipulated, among other criteria, a robust structure which can be constructed within a breakwater and can generate electricity from a fairly mild (in the order of Hs=0.5-1.5m)...master thesis 2009

Damsma, T. (author)Dune evolution on natural and nourished beaches on an engineering timescale is not well understood. Using a study of both literature, and data which has been gathered of the Dutch coast, a new hypothesis regarding the causes of variability in dune evolution is proposed. Following this hypothesis assumptions are made on the basis of which a...master thesis 2009

Vinke, F.R.S. (author)The effect of introducing an air film around a submerged water jet is examined in laboratory experiments. The objective is to reduce the friction forces between the water jet and the ambient fluid, making a jet potentially more effective at a larger distance. The test are conducted at a physical scale comparable to dredging practise, contrary to...master thesis 2009

Narayan, S. (author)A study of the effectiveness of mangroves in attenuating cyclone- induced waves was done using the SWAN 40.55MOD numerical model. Hydraulic parameters during extreme events and local mangrove vegetation parameters were estimated for the Kanika Sands mangrove island near the upcoming Dhamra Port in Orissa, India. Simplified generic analyses were...master thesis 2009

Bakker, S.A. (author)For a proposed liquefied natural gas export facility, Olokola LNG (OKLNG), located at the western limits of the Niger Delta in Nigeria a 10 km long and 17 m deep approach channel is designed for tankers to reach the terminal at the shoreline. Mud is expected to be deposited in the channel because of the persistent swell climate which mobilizes...master thesis 2009

Egon, A. (author)Coral reefs are highly diverse ecosystems that provide food, income, and coastal protection for hundreds of millions of coastal dwellers. They are found in tropical and semi tropical areas spread throughout South-east Asia, the Caribbean, the Indonesian archipelago, on Australian coasts and in the Pacific islands. Coral reefs are subject to both...master thesis 2009

Ho, J.C. (author)The rise of sea level increases the risk of coastal flooding by increasing the probability of occurrence of flood event at a given height. The essence of coastal planning and management in the future relies on an accurate coastal flood risk assessment with regards to sea level rise. Through the set up of flood risk assessment model in Geographic...master thesis 2009

Van Zwicht, B.N.M. (author)This thesis is about the influence of the specific weight on the stability of single layer interlocking armour units on rubble mound breakwaters. The hydraulic stability of the Xbloc armour unit is expressed by the stability number which is based on the assumption of dominance of lift, drag and gravity forces. If other forces have significant...master thesis 2009

Zuidgeest, R.F.J. (author)Op moment van schrijven is de aanleg van Maasvlakte 2 in volle gang. Het masterplan is echter nog in ontwikkeling, maar steeds meer keuzes worden vastgelegd. Daarom moet onderzocht worden of er op Maasvlakte 2 een ruimteclaim voor een Binnenvaart Service Centrum (BSC) moet blijven staan. Een BSC is een neutrale binnenvaartterminal waar een deel...master thesis 2009
