Henny, A. (author), Bronsvoort, K. (author)A remote guesthouse in the Brazilian province of Rio de janeiro is using electricity from the nuclear fed power grid. The owner would like to change the energy supply from nuclear to hydropower if a hydropower plant would produce enough energy to keep the guesthouse running. A small hydropower plant could possibly produce enough energy for the...bachelor thesis 2009

Nordbeck, P.M. (author)Maasvlakte 2 is het project waarmee de haven van Rotterdam wordt uitgebreid. Het sluit direct aan op de huidige Maasvlakte. De havenbekkens van beide Maasvlaktes worden verbonden door de Yangtzehaven in westelijke richting door te steken naar Maasvlakte 2. De doorsteek bestaat uit een voorfase waarin een kanaal wordt gegraven ten behoeve van de...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

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

Van Kester, D.C.P. (author)The goal of this master thesis is to describe the spatial distribution of the wave overtopping discharge over and behind the crest of a coastal defence structure. The influence of the most relevant parameters on this process is explored. This research has been performed by means of a physical model. The following relevant parameters were varied...master thesis 2009

Hoonhout, B.M. (author)The most densely populated and economical most valuable areas in The Netherlands lie below mean sea level. These areas are protected against the sea by a joint coastal dune system. The vital importance of this dune system is reflected in the extensive collection of Dutch legal regulations that ensure the safety level of the dunes. The assessment...master thesis 2009

Den Boer, V.J.E. (author), Joosten, D.A.W. (author), Melman, F.C.R. (author), Post, S. (author)The starting point for this project are the severe erosion problems at the Pacuare Nature Reserve, situated on the Caribbean coast of Costa Rica. The Reserve’s installations are situated next to a lagoon which is separated from the open sea by a barrier beach. The lagoon is connected on the landward side to local river? and channel system....student report 2009

(author)The beach in front of the hotel Sirius is suffering from a retreating coastline. Bathymetry and beach profiles were measured. With the data from previous years the long term evolution of the coast was analyzed. The main conclusions were that the beach in front of the Sirius hotel is still suffering from erosion and if this erosion trend...student report 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

Van der Woerdt, W. (author), Van den Bosch, I. (author), Heerema, R. (author), Ruijs, M. (author)Master project report. The hydraulic efficiency of the river Araranguá will be increased by the construction of jetties at the mouth of the river. The river tends to migrate from south to north which decreases the hydraulic efficiency and causes flooding upstream during events of high discharge. To stop the migration the construction of jetties...student report 2009

Eslami Arab, S. (author)Groins are old and intuitive means of reducing erosion and are found along the coast worldwide, although according to CEM (Coastal Engineering Manual 2003), “they are probably the most misused and improperly designed of all coastal structures”. The original purpose of groins was to reduce local erosion, that is, to hold the width of beach in...master thesis 2009

Van der Linde, J.P. (author)Two dimensional physical model tests are executed with Xbloc armour units on low crested structures to answer the objective. On the basis of findings in the literature study it can be expected that the stability of the Xbloc elements on low-crested breakwaters is a function of crest freeboard and crest width. The crest freeboard (Rc/Dn) varied...master thesis 2009

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

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

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

Van der Ziel, F. (author)The second Delta-committee (September 2008) foresees difficulty in resolving flood safety issues for Rotterdam and Dordrecht if high river runoffs are still running through the New Waterway. A new safety issue, induced by climate changes, lies in the combination of closed sea defensives and relatively high river runoffs at the same time. A...master thesis 2009

Kroon, J. (author)In numerical modelling of water movement wetting and drying is a well known problem. The governing equations are not valid in the dry part of the computational domain which may result in problems with mass conservation, negative water depths and artificially enlarged gradients. A method is proposed that allows for the surface elevation to become...master thesis 2009

Benit, M.P. (author)As waves enter the surf-zone, the wave spectra undergo drastic transformations because of depth-induced breaking and triad interactions. Any arbitrary spectrum will converge towards a smooth, universal shape in which initially higher harmonic peaks emerge that disappear as wave propagate further into the surf-zone. The current formulation of...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
