Overes, P.H.P. (author), Borsje, B. W. (author), Luijendijk, Arjen (author), Hulscher, S. J.M.H. (author)Sand waves are found on shallow, sandy seabeds throughout the world and their dynamics may pose an imminent threat to offshore construction. Therefore, there is a pressing need to understand bed level dynamics in sand wave areas. These bed level dynamics lead to variations in sand wave shape and migration rate over time. However, these...journal article 2024

Cortes Arevalo, V.J. (author), den Haan, Robert Jan (author), Berends, Koen D. (author), Baart, F. (author), van der Voort, Mascha (author), Hulscher, Suzanne J.M.H. (author)Transdisciplinary research requires improved knowledge exchange between science and practice. Such improvements include diversifying and scaling up knowledge accessing and sharing through online platforms. We conducted twenty interviews informed by behavioral science methods to clarify the aim, components, and participants' perspectives on the...journal article 2023

(author), van der Meulen, Bas (author), Herget, Jürgen (author), Hulscher, Suzanne J.M.H. (author)Reconstructions of the most severe historic flood events contribute to improved quantification of design discharges corresponding to large return periods. Reducing the uncertainty of design discharges has a great significance in constructing proper flood defences to protect the hinterland from future flooding. However, reconstructions of the...journal article 2023

(author), Hulscher, S. J.M.H. (author)The present work presents physical laboratory measurements of surface elevation and pore water pressures in a fine sand bed under bichromatic waves in a large-scale laboratory experiment. This was done at three cross-shore locations in the swash zone, with pressures being measured at different depths in the bed. The measurements show that the...journal article 2023

Poppema, D.W. (author), Baas, Andreas C.W. (author), Hulscher, Suzanne J.M.H. (author), Wijnberg, Kathelijne M. (author)Buildings affect aeolian sediment transport and bedform development in sandy environments. Cellular automaton (CA) models have, however, only been used to simulate natural bedform dynamics. This study extends a well-known aeolian CA model to include sediment dynamics around buildings, and uses this model to explore the interaction of building...journal article 2022

Chen, W. (author), Warmink, J.J. (author), van Gent, M.R.A. (author), Hulscher, S.J.M.H. (author)The mean overtopping discharge and the overtopping flow parameters related to individual overtopping events are often used to characterize the wave overtopping processes at dikes. Roughness, berms and oblique waves have significant effects on the wave overtopping processes at dikes while these effects are still not fully understood. A 2DV...journal article 2022

(author)We present a fully coupled 2DV morphodynamic model, implemented in OpenFOAM<sup>®</sup> that is capable of simulating swash-zone morphodynamics of sandy beaches. The hydrodynamics are described by the Reynolds-averaged Navier–Stokes (RANS) equations with a (Formula presented.) turbulence model and the Volume of Fluid (VoF) approach for...journal article 2022

(author)Salt marshes can contribute to coastal protection, but the magnitude of the protection depends on the width of the marsh. The cross-shore width of the marsh is to a large extent determined by the delicate balance between seaward expansion and landward retreat. The influence of the magnitude of daily occurring mild weather conditions and...journal article 2022

Poppema, Daan W. (author), Wijnberg, Kathelijne M. (author), Mulder, Jan P.M. (author), Vos, S.E. (author), Hulscher, Suzanne J.M.H. (author)In sandy environments, like the beach-dune system, buildings not only affect the airflow, but also the aeolian sediment transport in their surroundings. In this study, we determine how the horizontal size of sediment deposition patterns around buildings depends on the building's dimensions. Four one-day experiments were conducted at the beach...journal article 2021

Duarte Campos, L.A. (author), Wijnberg, Kathelijne M. (author), Hulscher, Suzanne J.M.H. (author)In this study we tested to what extent grain count data from a laser particle counter, when enriched with granulometric data, can lead to accurate measurements of aeolian sediment fluxes in the field. Field experiments were conducted at Koksijde beach (Belgium) with a vertical array of five Wenglor fork sensors and co-located vertically...journal article 2021

(author), Pourteimouri, Paran (author)The long-term physical existence of sandy shores critically depends on a balanced sediment budget. From the principles of Building with Nature it follows that a sustainable protection of sandy shores should employ some form of shore nourishment. In the spatial design process of urbanized sandy shores, where multiple functions must be integrated,...journal article 2021

Willemsen, Pim W.J.M. (author), Borsje, Bas W. (author), Vuik, V. (author), Bouma, Tjeerd J. (author), Hulscher, Suzanne J.M.H. (author)Foreshores consisting of both bare tidal flats and vegetated salt marshes are found worldwide and they are well studied for their wave attenuating capacity. However, most studies only focus on the small scale: just some isolated locations in space and only up to several years in time. In order to stimulate the implementation of foreshores...journal article 2020

(author)The composition of benthic species communities in the nearshore zone is closely related to the hydrodynamic and morphodynamic conditions. Sustainable management of the coastal ecosystem requires knowledge about the natural dynamics as well as human-induced changes on the ecosystem. To improve our knowledge of the benthic species distribution...journal article 2020

Reef, K.R.G. (author), Roos, P.C. (author), Schuttelaars, H.M. (author), Hulscher, S.J.M.H. (author)Observations of barrier coasts around the world suggest that some systems do not conform to the O'Brien-Jarret law. Here we explain this by investigating how resonance and bottom friction affect the response of tidal inlets to variations in basin geometry. Therefore, we develop a morphodynamic barrier coast model that is based on the...journal article 2020

van Denderen, R. Pepijn (author), Schielen, R.M.J. (author), Straatsma, Menno W. (author), Kleinhans, Maarten G. (author), Hulscher, Suzanne J.M.H. (author)Side channels are commonly constructed to reduce the flood risk or to increase the ecological value of a river. Such artificial side channels generally aggrade. We categorize the development of side channels based on the sediment that is deposited in these channels. Based on this categorization, we determine the main mechanisms that affect their...journal article 2019

(author), Bouma, T.J. (author)Bed level dynamics at the interface of the salt marsh and tidal flat have been highlighted as a key factor connecting the long-term biogeomorphological development of the marsh to large-scale physical forcing. Hence, we aim to obtain insight into the factors confining the location of the marsh edge (i.e., boundary between tidal flat and salt...journal article 2018

Reef, Koen RG (author), Lipari, Giordano (author), Roos, Pieter C. (author), Hulscher, Suzanne J.M.H. (author)We present an idealized network model for storm surges in the Wadden Sea, specifically including a time-dependent wind forcing (wind speed and direction). This extends the classical work by H.A. Lorentz who only considered the equilibrium response to a steady wind forcing. The solutions obtained in the frequency domain for the linearized shallow...journal article 2018

Bomers, A. (author), Aguilar Lopez, J.P. (author), Warmink, JJ (author), Hulscher, Suzanne J.M.H. (author)Structures integrated in a grass-covered dike may increase erosion development. Currently, safety assessment methods for flood defences are only applicable for a conventional grass-covered dike and the effects of structures on dike cover erosion are poorly understood. Since many dikes have a road on top, it is important to study the effect of...journal article 2018

(author), de Groot, A.V. (author), Goessen, P. (author), van Gelder-Maas, C. (author)The land-sea interface is a very attractive location for humans to settle. In the case of low lying, sedimentary coastlines this can be a risky location, as these shorelines are inherently dynamic in nature. Accelerating rates of relative sea level rise will increase coastal erosion, creating world-wide growing demands for coastal protection...abstract 2017
