van Damme, M. (author), den Ouden-van der Horst, D. (author)Methods have been developed to predict how hydrodynamic loads acting on nearly saturated porous media are transmitted to the subsoil. In line with the effective stress principle of Terzaghi, these methods apply the boundary conditions that the effective stresses at the surface of a porous medium are zero, and that the pore water pressures...journal article 2024

Mares Nasarre, P. (author), García-Maribona, Julio (author), Mendoza Lugo, M.A. (author), Morales Napoles, O. (author)An accurate estimation of wind and wave variables is key for coastal and offshore applications. Recently, copulas have gained popularity for modelling wind and waves multivariate dependence, since accounting for the hydrodynamic relationships between them is needed to ensure reliable estimations of the required design values. In this study,...conference paper 2023

Blom, Mike (author)The development of floating islands is an attractive option to provide living/working spaces at sea, as it would be a more economical solution for many locations at sea where the water depth is high. However, large second-order wave forces cause the floating island mooring system to become expensive as the wave height increases. So, in many...master thesis 2022

Wani, F.M. (author)Among different ways of harnessing tidal energy, tidal stream turbines are gaining popularity over traditional tidal dams. This is owing to the lower capital cost, and potentially lower ecological impact of tidal turbines. However, compared to more developed sources of energy, tidal energy remains expensive, which impedes its large-scale...doctoral thesis 2021

Wani, F.M. (author), Shipurkar, U. (author), Dong, J. (author), Polinder, H. (author)This paper compares active and passive cooling systems in tidal turbine power electronic converters. The comparison is based on the lifetime of the IGBT (insulated gate bipolar transistor) power modules, calculated from the accumulated fatigue due to thermal cycling. The lifetime analysis accounts for the influence of site conditions, namely...journal article 2021

Bosboom, J. (author), Stive, M.J.F. (author)This textbook on Coastal Dynamics focuses on the interrelation between physical wave, flow and sediment transport phenomena and the resulting morphodynamics of a wide variety of coastal systems. The textbook is unique in that it explicitly connects the dynamics of open coasts and tidal basins; not only is the interaction between open coasts and...book 2021

Schmidt, Anneliese (author)Sand ripples are small (10 cm height) bed forms which occur in the nearshore and surf zone under the impact of both waves and currents. They impact the roughness of the bed used in models of this zone, and contribute to sediment transport. Predictions of their geometry are important to properly model roughness, so correlations between the waves...master thesis 2020

Dang, Y. (author), Grundel, D.A.J. (author), Youk, H.O. (author)Cells form spatial patterns by coordinating their gene expressions. How a group of mesoscopic numbers (hundreds to thousands) of cells, without pre-existing morphogen gradients and spatial organization, self-organizes spatial patterns remains poorly understood. Of particular importance are dynamic spatial patterns such as spiral waves that...journal article 2020

Sprong, Geert (author)The bulbous bow is a common feature for large displacement vessels. The purpose of the bulbous bow is to reduce the bow wave, hereby making use of wave cancellation theory. The main drawback of these type of bows is that the drag reduction effect is only present for a limited range of sailing speeds. If the transit velocity is altered, the...master thesis 2019

Maan, D.C. (author), van Prooijen, Bram (author), Wang, Zhengbing (author)We use the results of a one-dimensional morphodynamic model and the basis of the “Lagrangian equilibrium state” (Maan et al., 2015, https://doi.org/10.1002/2014JF003311) to derive a quantitative relationship between the progradation speed of tidal flats and the suspended sediment concentration in their adjacent waters and show that the speed...journal article 2019

de Angelis, L. (author)In this thesis, we explore the physics of optical singularities. We investigate them in light waves propagating randomly in a planar nanophotonic chip. With a custom-built nearfield microscope, we map the electromagnetic field resulting from the interference of these light waves. Our technique gives access to the full vectorial and complex...doctoral thesis 2018

van de Ven, Maartje (author)This study investigates nonlinear wave shape and the near-bed velocity influenced in the vicinity of a tidal inlet for the SEdiment supply At the WAdden Sea ebb-tidal Delta project. Wave nonlinearities occur when waves encounter a flow. An opposing flow leads to waves with higher peaks and reduced wave length. During a following flow, the waves...master thesis 2018

Sfikas, Ilias (author)Raising environmental concerns have stimulated the development of renewable energy, including energy from the oceans, which contain a huge potential. In this thesis, particular emphasis is given to wave energy, which can deliver up to 2 TW on a global scale. The aim of this thesis is to optimize the control system of the Symphony Wave Power...master thesis 2018

Kwant, Martijn (author)The North Sea is known for its marine activities, which need ocean data for safe operations. The ocean surface is described using the two-dimensional wave spectrum. This ocean wave spectrum can be estimated using wave buoys, wave models or remote sensing techniques. Wave buoys and numerical models are known to contain inaccuracies, which...master thesis 2017

Baudino Bessone, Matteo (author)Offshore wind energy is a fast-growing sector in the energy industry, and the cost of electricity per kilowatt-hour from offshore wind is decreasing significantly. Until now, offshore wind turbines are mainly installed on bottom-mounted foundations, which are economically feasible in shallow waters. This factor has limited the development of...master thesis 2017

de Jonge, Mark Pieter (author)Two important performance parameters of a ship are fuel consumption and motions in a seaway. Besides a well-designed hull, several appendages can be used to increase the performance. One of these is a resistance reducing fixed foil behind the transom of the ship. This wing has the potential to create large lift forces near the aft of the ship,...master thesis 2017

Van Schie, J.J.P. (author)The induced earthquakes in the north of the Netherlands cause problems for the shallow foundations. At this moment there is no generally accepted way to deal with these earthquakes. The NPR advises a combination of two methods to calculate the seismic bearing capacity of shallow foundations. In order to find out if this procedure is legitimately...master thesis 2016

Townend, I (author), Wang, Zhengbing (author), Stive, M.J.F. (author), Zhou, Z. (author)Whilst much attention has been given to models that describe wave, tide and sediment transport processes in sufficient detail to determine the local changes in bed level over a relatively detailed representation of the bathymetry, far less attention has been given to models that consider the problem at a much larger scale (e.g. that of...journal article 2016
