(author), de Schipper, M.A. (author)Quantitative predictions of marine and aeolian sediment transport in the nearshore–beach–dune system are important for designing Nature-Based Solutions (NBS) in coastal environments. To quantify the impact of the marine-aeolian interactions on shaping NBS, we present a framework coupling three existing process-based models: Delft3D Flexible...journal article 2024

(author), Ruessink, Gerben (author), Reniers, A.J.H.M. (author), Aarninkhof, S.G.J. (author)A field campaign was carried out at a sheltered sandy beach with the aim of gaining new insights into the driving processes behind sheltered beach morphodynamics. Detailed measurements of the local hydrodynamics, bed-level changes and sediment composition were collected at a man-made beach on the leeside of the barrier island Texel, bordering...journal article 2024

Kettler, T.T. (author), de Schipper, M.A. (author), Luijendijk, Arjen (author)Projections of high rates of sea level rise have stimulated proposals for adaptation strategies with increasingly high nourishment volumes along sandy beaches. An underlying assumption is that coastal profiles respond rapidly to nourishments by redistributing sediments towards a (new) equilibrium shape. However, this perception may not be...journal article 2024

van Westen, B. (author), Leijnse, Tim (author), de Schipper, M.A. (author), Cohn, Nicholas (author), Luijendijk, Arjen (author)Traditionally, independent tools have been used to simulate wave- or wind-driven processes to simulate coastal morphology change. Coupled models that cross the land-sea division and integrate these collective processes can increase our knowledge on complex morphodynamic interactions and improve predictions of the foreshore, beach, and dune...conference paper 2023

Kettler, T.T. (author), de Schipper, M.A. (author), Luijendijk, Arjen (author), Aarninkhof, S.G.J. (author)Projections of high rates of sea level rise have stimulated proposals for adaptation strategies with increasingly high nourishment volumes. Nourishment strategies involving higher sand volumes can be accomplished by increasing the volume of individual nourishments or by decreasing the time interval between successive nourishments. The optimal...conference paper 2023

de Schipper, M.A. (author), Onnink, Casper J. (author), Bruder, Brittany L. (author), Brodie, Katherine L. (author)Nearshore berms or shoreface nourishments are sandy coastal interventions in which sediment is placed seaward of the land-water interface. These projects rely on natural forces to redistribute sediment in the nearshore zone and mitigate erosion, increase beach width or both. However, there is still limited knowledge on the connection between the...conference paper 2023

Lee, Seok Bong (author), Wengrove, Meagan E. (author), de Schipper, M.A. (author), Hopkins, Julia (author), Kleinhans, Maarten G. (author), Ruessink, Gerben (author)We investigate pathways of sediment diffusion for a Gaussian-shaped sand mound subjected to monochromatic waves. Our unique results nearly close the sediment budget by quantifying each of the sediment transport processes responsible for mound diffusion associated with sediment flux due to slope driven transport and ripple migration. Downslope...journal article 2023

Schlacher, Thomas A. (author), Maslo, Brooke (author), de Schipper, M.A. (author)Coasts form the universal stage on which people interact with the global ocean. Our history is inextricably intertwined with the seashore, being a rich tapestry of archaeological sites that paint a vivid picture of people hunting, foraging, fishing and scavenging at the edge of the sea. Seascapes inspire diverse art forms celebrated through the...journal article 2022

Kroon, J. (author), de Schipper, M.A. (author), de Vries, S. (author), Aarninkhof, S.G.J. (author)Sandy nourishments can provide additional sediment to the coastal system to maintain its recreational or safety function under rising sea levels. These nourishments can be implemented at sandy beach systems, but can also be used to reinforce gray coastal infrastructure (e.g., dams, dikes, seawalls). The Hondsbossche Dunes project is a combined...journal article 2022

(author)Field observations of small scale seabed morphology were obtained over 4 weeks at two locations separated 66 m along a cross-shore transect during the 2014 MEGAPEX Experiment conducted as part of the longer term Sand Engine mega-nourishment project along the North Sea Coast of The Netherlands.

(author), Castelle, Bruno (author)Observations from wave basin experiments and wave-resolving numerical simulations demonstrate the effect of wave-current interaction on shear stress around a sandy mound. Observations from the wave basin show that the mound deformation rate and morphological patterns depend on the mixture of waves and currents in the incident flow conditions....journal article 2022

(author)Coastal safety assessments with wave-resolving storm impact models require a proper offshore description for the incoming infragravity (IG) waves. This boundary condition is generally obtained by assuming a local equilibrium between the directionally-spread incident sea-swell wave forcing and the bound IG waves.

Roest, Lambertus W.M. (author), de Vries, S. (author), de Schipper, M.A. (author), Aarninkhof, S.G.J. (author)Recently, mega feeder nourishments have been proposed as a new strategy to nourish sediment-starving beaches. This strategy involves the placement of a large, concentrated sediment volume at a single location along the coast. Wind, waves and currents act as the natural agents to spread the sediment alongshore over the course of years to decades....journal article 2021

(author)Plastics originating from land are mainly transported to the oceans by rivers. The total plastic transport from land to seas remains uncertain because of difficulties in measuring and the lack of standard observation techniques. A large focus in observations is on plastics floating on the water surface. However, an increasing number of...journal article 2021

Kroon, J. (author), de Schipper, M.A. (author), van Gelder, P.H.A.J.M. (author), Aarninkhof, S.G.J. (author)Sand nourishments are increasingly applied as adaptive coastal protection measures. Predictions of the evolution of these nourishments and their impact on the surrounding coastline contain many uncertainties. The sources that add to this uncertainty can be delineated between intrinsic and epistemic uncertainty, i.e. inevitably in the system or...journal article 2020

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

Gerben (author)Shoreface nourishments are commonly applied for coastal maintenance, but their behaviour is not well understood. Bathymetric data of 19 shoreface nourishments located at alongshore uniform sections of the Dutch coast were therefore analyzed and used to validate an efficient method for predicting the erosion of shoreface nourishments. Data shows...journal article 2019

Morphodynamic acceleration techniques for multi-timescale predictions of complex sandy interventionsLuijendijk, Arjen (author), de Schipper, M.A. (author), Ranasinghe, Roshanka (author)Thirty one percent (31%) of the world's coastline consists of sandy beaches and dunes that form a natural defense protecting the hinterland from flooding. A common measure to mitigate erosion along sandy beaches is the implementation of sand nourishments. The design and acceptance of such a mitigating measure require information on the expected...journal article 2019
