van Wiechen, P.P.J. (author), Rutten, J. (author), Mieras, Ryan (author), Anarde, Katherine (author), Wrobel, Magda (author), Tissier, M.F.S. (author), de Vries, S. (author)Storm conditions can lead to excessive dune erosion with potential floods as a consequence. Barrier islands and low-lying countries protected by dunes are especially vulnerable to dune erosion. To properly assess the risks these areas face, a clear understanding of the physical processes during dune erosion is required.<br/><br/>An international...conference paper 2022

Hallin, E.C. (author), Huisman, Bas (author), Krijnen, Ine (author), de Vries, S. (author)In recent years, dune-in-front-of-dike projects have been carried out at several locations, e.g. at Raversijde and Oosteroever in Belgium and the Hondsbossche dunes in the Netherlands. In the near future, many coastal defence systems require reinforcement to adapt to rising sea levels, and often, natural values along the coasts may also be...conference paper 2022

Vos, S.E. (author), van IJzendoorn, Christa (author), Kuschnerus, M. (author), de Vries, S. (author)The European beach-dune systems are under increasing pressure due to urbanization, beach tourism and the effects of climate change like rising sea level and increased storm intensity. Building with nature solutions (Stive et al., 2013) are advocated as an effective and adaptable approach to protect sandy coasts in the future. This approach...conference paper 2022

de Vries, R. (author), Wolleswinkel, Rob E. (author), Hoogreef, M.F.M. (author), Vos, Roelof (author)Battery-electric aviation is commonly believed to be limited to small aircraft and is therefore expected have a negligible impact on the decarbonization of the aviation sector. In this paper we argue that, with the correct choice of design parameters and top-level aircraft requirements, the addressable market is actually substantial. To...conference paper 2024

Wolleswinkel, Rob E. (author), de Vries, R. (author), Hoogreef, M.F.M. (author), Vos, Roelof (author)Thus far, battery-electric propulsion has not been considered a promising pathway to climate-neutral aviation. Given current and expected battery technology, in most literature battery-electric aircraft are only considered feasible for short ranges (< 400 km) and small payloads (< 19 pax). As a result, battery-electric aircraft development...conference paper 2024

Duivenvoorden, R.R. (author), Voskuijl, M. (author), Morée, Lars (author), de Vries, J. (author), van der Veen, Finbar (author)The use of formation flight to achieve aerodynamic benefit as applied to rotorcraft is, unlike its fixed-wing counterpart, an unproven principle. This document presents a proof-of-concept of rotorcraft formation flight through a numerical research study, supported by results from an independent wind-tunnel experiment. In both cases, two...conference paper 2020

Bölk, S.A. (author), de Vries, R. (author), van Arnhem, N. (author), Veldhuis, L.L.M. (author)In this study, unsteady RANS simulations are performed to investigate the effect of over-the-wing (OTW) propeller inclination on the aerodynamic interaction with a wing featuring a plain flap. A comparison to experimental data shows that the numerical approach is capable of modeling the wing and propeller separately and can capture the effect of...conference paper 2021

(author)Many new logistics initiatives arise based on the principles of resource sharing through crowdsourcing. Sharing unused and/or underused resources can deliver new efficiencies in the logistics value chain in an industry where efficiency is the name of the game.

(author), Mol, Jan Willem (author), Wilmink, Rinse (author)Infragravity (IG) waves are key drivers for coastal erosion and thus need to be properly included in process-based modelling of coastal hazards. Uncertainties remain regarding the offshore boundary conditions for these long waves. Typically, only bound IG waves are included at the boundary, which means that the possible contribution of free IG...conference paper 2023

Marcus, E. A.P. (author), de Vries, R. (author), Raju Kulkarni, A. (author), Veldhuis, L.L.M. (author)This paper addresses the aerodynamic performance and numerical modeling of over-the-wing propellers. Installing the propeller above a wing has the potential to increase wing lift-to-drag ratio, high-lift capabilities, and to reduce flyover noise. However, the prediction of its performance is difficult, since research on the aerodynamic...conference paper 2018

For concrete structures gathering field data by performing a proof load test offers detailed information about the structural performance.

de Vries, R. (author), Vos, Roelof (author)The goal of this study is to analyze how the aero-propulsive benefits of an over-the-wing distributed-propulsion (OTWDP) system at component level translate into an aero-propulsive benefit at aircraft level, and to determine whether this enhancement is sufficient to lead to a reduction in overall energy consumption. For this, the preliminary...conference paper 2022

In case limited information of the structure is available or its condition is of concern, proof load testing may be used to demonstrate sufficient load-carrying capacity.

(author)Cua Dai Beach located adjacent to Cua Dai Inlet is a typical, seasonally varying tidal inlet. This famous beach has suffered extreme erosion since 1995 due to an apparent irregular-periodic process, a decrease of sediment supply from the river and its estuaries and increased squeeze by coastal developments.
