Kuai, Y. (author), Aarninkhof, S.G.J. (author), Wang, Zhengbing (author)Intertidal flats are of great socio-economic and ecological importance in defending the coastal cities from flooding, providing resources for land reclamations and habits for wildlife. On the intertidal flats, milder profiles are usually featured with finer sediment. However, we find the opposite relationship between the alongshore variation in...journal article 2023

Mata, Marisol Irías (author), van Gent, M.R.A. (author)Numerical modelling of wave interaction with rock-armoured rubble mound breakwaters has been performed to study wave overtopping. The influences of the slope angle, a berm in the seaward slope, a protruding crest wall, a recurved parapet, and the wave steepness have been studied using a validated CFD model (OpenFOAM). The numerical modelling...journal article 2023

Pol, J.C. (author), Kindermann, P.E. (author), van der Krogt, M.G. (author), van Bergeijk, Vera M. (author), Remmerswaal, G. (author), Kanning, W. (author), Jonkman, Sebastiaan N. (author), Kok, M. (author)Structural reliability analysis often considers failure mechanisms as correlated but non-interacting processes. Interacting failure mechanisms affect each others performance, and thereby the system reliability. We describe such interactions in the context of flood defenses, and analyze under which conditions such interactions have a large impact...journal article 2023

Mohsan, M. (author), Vardon, P.J. (author), Vossepoel, F.C. (author)Data assimilation methods have been implemented on a slope stability problem, and the performance of different constitutive models and data assimilation schemes has been investigated. In the first part, a data assimilation scheme called the ensemble Kalman filter (EnKF) is implemented using a finite element model (FEM) and its performance with...conference paper 2023

Alhaddad, S.M.S. (author), Weij, Dave (author), van Rhee, C. (author), Keetels, G.H. (author)As a result of the dilation of soil matrix, dense submarine sand slopes can temporarily be steeper than the natural angle of repose. These slopes gradually fail by the detachment of individual grains and intermittent collapses of small coherent sand wedges. The key question is whether steep disturbances in a submarine slope grow in size ...journal article 2023

Wang, Bin (author), Wang, Di (author), Hicks, M.A. (author), Feng, Xia Ting (author)Retrogressive failures occur in slopes consisting of sensitive materials such as snow or quick clay. They can be triggered by a small disturbance at the slope toe, but can cause propagated failure spreading miles away. Understanding the physical mechanism and predicting the retrogressive failure process are particularly important. Previous...journal article 2023

Kool, J.J. (author)In the last century, approximately 100,000 people lost their lives during a flood event and over 1.4 billion people were affected. As the population and economic activities grow in flood-prone areas and the frequencies and intensities of flood events increase due to climate change, damage due to flooding is expected to increase. To limit and...doctoral thesis 2022

Michels, Dirk-Jan (author)On the east coast of Romania, at Eforie, coastal erosion manifests. To strengthen the coastal area a large coastal protection project was setup involving beach nourishment combined with the construction of breakwaters. The breakwaters are designed with the well-known modified Van der Meer formulas. To ensure confidence in the breakwaters...master thesis 2022

Lengkeek, H.J. (author)The Netherlands is inherently challenged by water, as a large part of the country lies below sea level and several major rivers in North-western Europe cross the country. The most prevalent form of protection from coastal and river floods in the Netherlands includes approximately 22,000 km of earthen dikes, of which 3800 km are primary flood...doctoral thesis 2022

van der Krogt, M.G. (author)Dikes are crucial for the protection against floods. One of the ways in which dikes can fail is by the instability of the inner slope. Credible probabilities of failure for slope stability are essential for the safety assessment of existing dikes and the design of dike reinforcements. This dissertation focuses on improving failure probability...doctoral thesis 2022

Mohanty, Avinab (author)Vibratory installation of piles and casings can be extremely economical, therefore the contractors prefer pile driving. When compared to impact pile driving, vibratory pile driving generates less noise but this installation method is still fraught with uncertainties (Rausche 2003). Environmental effects (such as ground vibrations) have negative...master thesis 2022

Kamphuis, Arian (author)Climatic conditions in uence peak discharges in rivers and change sea levels; therefore, attention to the safety of dikes is of ever growing importance. Macro instability is one of the dike failure mechanisms that can inundate the hinterland. Soil heterogeneity plays an important role in assessing dike safety, especially for slope stability,...master thesis 2022

Chen, Y. (author), Gong, J. (author), Staszewski, R.B. (author), Babaie, M. (author)In this article, we present a 4.5-5.1-GHz fractional-N digitally intensive phase-locked loop (DPLL) capable of maintaining its performance in face of a large supply ripple, thus enabling a direct connection to a switched-mode dc-dc converter. Supply pushing of its inductor-capacitor (LC) oscillator is suppressed by properly replicating the...journal article 2022

Dào, H.T. (author), Hofland, B. (author), Stive, M.J.F. (author), Mai, Tri (author), Ngo, Anh (author)Wooden fences are nature-based supporting structures to restore mangroves in the Mekong Delta. The hydraulic functioning of wooden fences was studied in previous studies. However, the role of bathymetry in the dissipation and damping of waves by wooden fences has not been studied yet. Thus, in this study, a numerical approach is used to find...conference paper 2022

Varkey, D. (author), Hicks, M.A. (author), Vardon, P.J. (author)This paper investigates the influence of three forms of uncertainty on the probabilistic stability of an idealised 3D embankment slope. These are: 1D spatial variability in the external geometry of the slope along its length, 2D spatial variability in the depth of the boundary between the embankment material and the foundation layer, and 3D...journal article 2022

Jamalinia, E. (author)Large areas of the Netherlands are below the sea level, and a network of primary and secondary (regional) dikes protect these areas from inundation. Regular assessments and monitoring are implemented with the intention of ensuring the safety of the protected areas. However these assessments usually ignore that these dikes are subject to various...doctoral thesis 2021
