de Rooij, Steven (author)Microwave Kinetic Inductance Detectors (MKIDs) are remarkable photon detectors, that have single photon detection and energy resolving capabilities in the near-infra red and higher frequency range. At lower frequencies, MKIDs are excellent radiation detectors as well, because of their high sensitivity and natural multiplexing capabilities, which...master thesis 2020

Foortse, B. (author)People all around the world live and work in low-lying areas. Low-lying areas have to be protected against high water levels in rivers and at sea by a water protection system (e.g. by dunes, dikes and barriers). Dikes are an important component within water protection systems. Generally, dikes are described as elongated naturally occurring or...master thesis 2016

Van den Akker, P. (author)At the moment, for determining the safety of the dike ring areas around the IJsselmeer a possible failure of the Afsluitdijk is assumed to have no influence on loads occurring on the IJsselmeer dikes. As failure of the Afsluitdijk is always possible, the consequences of such a failure should be investigated. The objective of this thesis is to...master thesis 2015

De Vet, P.L.M. (author)Currently, morphodynamic models as XBeach show substantial overestimations of the erosion rates during breaching and overwash events at barrier islands. The presently used limitations on the Shields parameter and the sediment concentration do hinder erosion, but have undesirable side effects, e.g. the breaching process is suppressed. By...master thesis 2014

Gan, S.W. (author)Coastal erosion is greatly accelerated by the presence of agriculture and aquaculture activities (oil palm plantation or shrimp farming involving the construction of earth bunds) in the natural process. Earth bunds or dykes are constructed to prevent entrainment of seawater into the agriculture area behind the bunds so as to protect these...master thesis 2014

Lemmens, D.D.M.M. (author)Sand dikes have a sand core and a clay layer to protect the core against erosion. It is not unlikely that this layer fails due to several failure mechanisms, exposing the sand core to water. This can be catastrophically when water is overtopping the dike. In case the protective cover fails, water can flow over the core and erode the sand,...master thesis 2014

Tavouktsoglou, N.S. (author)Wave transmission is a very important design parameter for submerged porous breakwater design, as it defines the dimensions of the breakwater as well as the cost and construction process. The spatial distribution of the wave transmission parameter influences the current pattern on the lee of the breakwater and therefore the sediment transport...master thesis 2013

Toh, H.L. (author)Light is attenuated by materials present in the water column by scattering and absorption. The knowledge of light attenuation and its contributing factors influencing visibility/turbidity is unknown in Singapore waters. This MSc thesis consists of field measurement, laboratory experiment and numerical modelling in 3 parts; parameterisation of...master thesis 2012

Do, P.B. (author)Desalinated or demineralised water or even soft water is characteristically low in hardness, alkalinity and pH. Thus, these kinds of water need to be re-conditioned (re-mineralized) before distributing for usage as drinking water. The produced water is expected to satisfy the following requirements: safe quality for human health, no quality...master thesis 2012

Ren, Y. (author)The main objective of the study is to understand the effects of breach properties (e.g. the top width, the depth and the bottom width of the breach) on the breach flow. The breach flow was modeled as flow over a compound broad-crested weir. A laboratory experiment was carried out with a fixed weir model in a flume. Five cases with different...master thesis 2012

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

Nterekas, D. (author)This research investigates the Wilnis dike failure that occurred in the dry summer of 2003. It is believed that drought played an important role in decreasing the stability of the dike, finally leading to failure. In the reported MSc project the situation during drought is simulated with the help of finite element method programs Plaxis and...master thesis 2009

McCall, R.T. (author)The primary objective of this thesis is to generate a 2DH-numerical model to simulate dune overwash. The first stage in this is achieved by modifying the program code of an existing overwash model in development, XBeach, to enable 2DH calculations. In the second stage the hydrodynamics of the model are verified using theoretical and laboratory...master thesis 2008

Poort, M.C.L. (author)Detailed laboratory measurements of the wave and current field induced by bi-chromatic waves incident on an artificial surfing reef are presented. Strong wave focussing occurs on the surfing reef. Both PTV and in-situ measurements are reported that show the presence of a strong rip current flowing oblique off-shore. Observed water level set-up...master thesis 2007

Wierenga, J.N. (author)Door het uitmonden van verschillende rivieren in het IJsselmeer is er een permanente aanvoer van water. Een groot deel van het aangevoerde water wordt onder verval met spuisluizen in de Afsluitdijk afgevoerd. De capaciteit van deze spuisluizen is niet meer voldoende. Dit is het gevolg van groeiende pieken in de aanvoer van water naar het...master thesis 2007

Trung, L.H. (author)Wave surfing is existing and becoming more attractive in the Netherlands. However natural wave conditions are not suited to encourage the sport. To improve the surf conditions of the local waves, Artificial Surf Reefs are potential solutions. As a part of intentions to optimise the design of Artificial Surf Reefs, this thesis is aimed at gaining...master thesis 2006

Kleinlugtenbelt, R. (author)The Noord/Zuidlijn (North/South Line) is a 9.5 kilometers long metro line tunnel bored underground through the historical city centre of Amsterdam. The Tunnel Bore Machine (TBM) will initiate unacceptable settlement of monumental buildings in the surroundings. At these locations, mitigating measures are defined. One of the measures that will be...master thesis 2005

Relation between the design of creeks and the morphology of river bypasses in estuarine environmentsHuisman, B.J.A. (author)Framework Within the framework of the 'Room for the River' policy in the Netherlands several river bypasses are studied. One of these projects is the Noordwaard, which is a special project, because a large polder (about 20km2) will change into a tidal influenced area. The primary water defences in the North of the polder (Nieuwe Merwede) are to...master thesis 2005
