van Bemmelen, C.W.T. (author), de Schipper, M.A. (author), Darnall, J. (author), Aarninkhof, S.G.J. (author)Beach scarps are nearly vertical seaward facing sandy cliffs within the cross-shore beach profile. These features are often associated with eroding (nourished) coastlines and can reach heights of O(2–3 m). An analysis of a six-year dataset of beach scarp presence at the nourished Sand Engine beach shows that the formation of beach scarps at the...journal article 2020

Gawehn, M.A. (author), van Dongeren, Ap (author), de Vries, S. (author), Swinkels, Cilia (author), Hoekstra, Roderik (author), Aarninkhof, S.G.J. (author), Friedman, Joshua (author)Coastal management in the Netherlands has the aim to defend coastal zones by preventing flooding and mitigating erosion. To that end, large-scale nourishments are placed in the nearshore, which are supposed to dynamically preserve the coastal zone over a timescale of years. To assess their effectiveness, these nourishments are monitored over...journal article 2020

(author), Tao, Jian Feng (author), Gong, Zheng (author), Wang, Zhengbing (author), van Maren, D.S. (author)The fast economic development of the People's Republic of China has created an increasing demand for usable land, resulting in large-scale land reclamations along the coastal zone. One of these regions is Tongzhou Bay (Jiangsu coast), a region characterized by large intertidal mudflats and deep tidal channels with potential for the...journal article 2020

Hendrikse, H. (author), Nord, Torodd S. (author)Interaction of sea or lake ice with vertically sided offshore structures may result in severe structural vibrations commonly referred to as ice-induced vibrations. With the surge in offshore wind developments in sub-arctic regions this problem has received increased attention over the last decade, whereas traditionally the topic has been mainly...journal article 2019

Yasin, Saima (author), Shakeel, A. (author), Iqbal, Tanveer (author), Ahmad, Fazeel (author), Mehmood, Hamayoun (author), Luckham, Paul F. (author), Ullah, Nehar (author)Nano-indentation is an interesting tool for analyzing nano-scale mechanical properties. The analysis of nano-mechanical properties as a function of experimental conditions is very critical for designing engineering components. In this study, nano-indentation experiments were performed by considering different values of amplitude (1, 5, 10 nm...journal article 2019

Van Dorsser, C. (author)NL: Scenario’s zijn belangrijk bij het evalueren van infrastructuur beleid, maar helaas zijn er gegronde redenen om te twijfelen aan de gangbare veronderstellingen ten aanzien van economische groei zoals gehanteerd in vrijwel alle officiële scenariostudies. Dit artikel bespreekt de in de Nederlandse "WLO referentiescenario's" gehanteerde...journal article 2016

(author)This study identifies and unravels the processes that lead to stratification and destratification in the far field of a Region of Freshwater Influence (ROFI). We present measurements that are novel for two reasons: (1) measurements were carried out with two vessels that sailed simultaneously over two cross-shore transects; (2) the measurements...journal article 2016

Cenedese, C. (author), Gatto, V.M. (author)Idealized laboratory experiments investigate the glacier–ocean boundary dynamics near a vertical glacier in a two-layer stratified fluid. Discharge of meltwater runoff at the base of the glacier (subglacial discharge) enhances submarine melting. In the laboratory, the effect of multiple sources of subglacial discharge is simulated by introducing...journal article 2016

Huibregtse, E. (author), Morales Napoles, O. (author), Hellebrandt, L. (author), Paprotny, D. (author), De Wit, S. (author)This paper presents a risk-based method to quantify climate change effects on road infrastructure, as a support for decision-making on interventions. This can be implemented in climate adaptation plans as an element of asset management. The method is illustrated by a specific case in which traffic on a road network is disrupted by the flooding...journal article 2016

Gallagher, Edith (author), Wadman, Heidi (author), McNinch, Jesse (author), Reniers, A.J.H.M. (author), Koktas, Melike (author)Grain size on the surface of natural beaches has been observed to vary spatially and temporally with morphology and wave energy. The stratigraphy of the beach at Duck, North Carolina, USA was examined using 36 vibracores (~1-1.5 m long) collected along a cross-shore beach profile. Cores show that beach sediments are finer (~0.3 mm) and more...journal article 2016

Steenstra, Remco (author), Hofland, Bas (author), Paarlberg, Andries (author), Smale, Alfons (author), Huthoff, Fredrik (author), Uijttewaal, W.S.J. (author)A stability parameter for rock in bed protections under nonuniform stationary flow is derived. The influence of the mean flow velocity, turbulence, and mean acceleration of the flow are included explicitly in the parameter. The relatively new notion of explicitly incorporating the mean acceleration of the flow significantly improves the...journal article 2016

Maan, D.C. (author), van Prooijen, B.C. (author), Wang, Z.B. (author), de Vriend, H.J. (author)Various studies have identified a strong relation between the hydrodynamic forces and the equilibrium profile for intertidal flats. A thorough understanding of the interplay between the hydrodynamic forces and the morphology, however, concerns more than the equilibrium state alone. We study the basic processes and feedback mechanisms underlying...journal article 2015

Tissier, M. (author), Bonneton, P. (author), Michallet, H. (author), Ruessink, B.G. (author)The cross-shore evolution of individual wave celerity is investigated using two highresolution laboratory experiments on bichromatic waves. Individual waves are tracked during their onshore propagation and their characteristics, including celerity, are estimated. The intrawave variability in celerity is low in the shoaling zone but increases...journal article 2015

Hu, Z. (author), Wang, Z.B. (author), Zitman, T.J. (author), Stive, M.J.F. (author), Bouma, T.J. (author)Dynamic equilibrium theory is a fruitful concept, which we use to systematically explain the tidal flat morphodynamic response to tidal currents, wind waves, sediment supply, and other sedimentological drivers. This theory stems from a simple analytical model that derives the tide- or wave-dominated tidal flat morphology by assuming that...journal article 2015

Zerfu, T. (author), Beevers, L. (author), Crosato, A. (author), Wright, N. (author)This paper considers the erodible river corridor, which is the area in which the main river channel is free to migrate over a period of time. Due to growing anthropogenic pressure, predicting the corridor width has become increasingly important for the planning of development along rivers. Several approaches can be used to predict the future...journal article 2015

Hoonhout, B.M. (author), Radermacher, M. (author), Baart, F. (author), Van der Maaten, L.J.P. (author)Large, long-term coastal imagery datasets are nowadays a low-cost source of information for various coastal research disciplines. However, the applicability of many existing algorithms for coastal image analysis is limited for these large datasets due to a lack of automation and robustness. Therefore manual quality control and site- and time...journal article 2015

Gourdin-Bertin, S. (author), Chassagne, C. (author), Bernard, O. (author), Jardat, M. (author)In electrolyte solutions, an electric potential difference, called the Ionic Vibration Potential (IVP), related to the ionic vibration intensity, is generated by the application of an acoustic wave. Several theories based on a mechanical framework have been proposed over the years to predict the IVP for high ionic strengths, in the case where...journal article 2015

In Dutch flood defense reliability modeling, an efficient method for computing the failure probability of a system of correlated...journal article 2015

Gourdin-Bertin, S. (author), Chassagne, C. (author), Bernard, O. (author), Jardat, M. (author)In the framework of irreversible thermodynamics, we show that the sedimentation current in electrolyte solutions is mathematically equivalent to the low frequency limit of the ionic vibration current, appearing in the presence of an acoustic wave. This non-trivial result is obtained thanks to a careful choice of the reference frame used to...journal article 2015
