Chan, Kevin (author), Paardekooper, S. (author)Dust rings in protoplanetary discs are often observed in thermal dust emission and could be fa v ourable environments for planet formation. While dust rings readily form in gas pressure maxima, their long-term stability is key to both their observability and potential to assist in planet formation. We investigate the stability of the dust...journal article 2024

Ziampras, Alexandros (author), Nelson, Richard P. (author), Paardekooper, S. (author)Low-mass planets migrate in the type-I regime. In the inviscid limit, the contrast between the vortensity trapped inside the planet's corotating region and the background disc vortensity leads to a dynamical corotation torque, which is thought to slow down inward migration. We investigate the effect of radiative cooling on low-mass planet...journal article 2024

Bertozzi, Andrea (author), Niosi, Francesco (author), Jiang, X. (author), Jiang, Zhiyu (author)Numerical modeling of the floating offshore wind turbine (FOWT) dynamics plays a critical role at the design stage of a floating wind project. Still, there exist challenges for verification of efficient engineering models against experimental results. Recently, an experimental campaign was carried out for a 1:96 downscaled model of the OC4...journal article 2024

Xie, Weiming (author), Sun, J. (author), Guo, Leicheng (author), Xu, Fan (author), Wang, Xianye (author), Ji, Hongyu (author), Fan, Yaoshen (author), Wang, Zhengbing (author), He, Qing (author)Coastal tidal flats provide valuable ecosystems, but are highly sensitive to tidal dynamics, sea-level rise, and human activities. Tidal inundation depth and frequency are known to affect tidal flat morphodynamics. However, the causes, processes and extent remain uncertain, particularly given the associated changes in sediment availability. In...journal article 2023

Ziampras, Alexandros (author), Paardekooper, S. (author), Nelson, Richard P. (author)In radiatively inefficient, laminar protoplanetary discs, embedded planets can excite a buoyancy response as gas gets deflected vertically near the planet. This results in vertical oscillations that drive a vortensity growth in the planet's corotating region, speeding up inward migration in the type-I regime. We present a comparison between...journal article 2023

van Essen, S.M. (author), Seyffert, Harleigh C. (author)Green water and slamming wave impacts can lead to severe damage or operability issues for marine structures. It is therefore essential to consider their probability and loads in design. This is difficult, as impacts are both hydrodynamically complex and relatively rare. The complexity requires high-fidelity modeling (experiments or CFD),...journal article 2023

Leuven, Jasper R.F.W. (author), Niesten, Iris (author), Huismans, Y. (author), Cox, Jana R. (author), Hulsen, Lamber (author), van der Kaaij, Theo (author), Hoitink, A. J.F. (Ton) (author)Effects of sea-level rise (SLR) on future peak water levels in tidal deltas and estuaries are largely unknown, despite these areas being densely populated and at high risk of flooding. While the rates of SLR accelerate, many channels simultaneously experience channel deepening for navigation. With globally decreasing sediment supplies, most...journal article 2023

Barratt, Dylan (author), van den Bremer, T.S. (author), Adcock, Thomas A.A. (author)We perform simulations of random seas based on narrow-banded spectra with directional spreading. Our wavefields are spatially homogeneous and nonstationary in time. We truncate the spectral tail for the initial conditions at different cutoff wavenumbers to assess the impact of the spectral tail on the kurtosis and spectral evolution. We...journal article 2022

(author), Waqas, Muhammad Mohsin (author), Aziz, Rizwan (author), Shakoor, Aamir (author), Rizwan, Muhammad (author), Chauhdary, Junaid Nawaz (author)Groundwater is a primary source of freshwater provisions all around the world. Due to its limited availability, water has become a precious entity nowadays. The future accessibility of groundwater is endangered due to its massive exploitation, particularly in the irrigation sector. Therefore, the current study was conducted to assess the...journal article 2022

Klaver, S. (author), Nederhoff, C. M. (author), Giardino, A. (author), Tissier, M.F.S. (author), van Dongeren, A. R. (author), van der Spek, A.J.F. (author)Small island developing states are among the most vulnerable areas to the impact of natural hazards and climate change. Flooding due to storm surges and extreme waves, coastal erosion, and salinization of freshwater lenses are already a serious threat and could lead to irreversible consequences in the coming decades. Reef flat mining is one...journal article 2019

This paper reveals the relative importance of tide, surge, wind, and waves for the flow and sediment transport on large intertidal shoals. Results of an intensive field campaign have been used to validate a numerical model of the Roggenplaat intertidal...journal article 2018

Pearson, S.G. (author), Storlazzi, C.D. (author), van Dongeren, A. R. (author), Tissier, M.F.S. (author), Reniers, A.J.H.M. (author)Many low-elevation, coral reef-lined, tropical coasts are vulnerable to the effects of climate change, sea level rise, and wave-induced flooding. The considerable morphological diversity of these coasts and the variability of the hydrodynamic forcing that they are exposed to make predicting wave-induced flooding a challenge. A process-based...journal article 2017
