Liptiay, E.J.A. (author), Blom, A. (author), Sloff, C.J. (author)Over the past century, the main channel of the Waal has experienced erosion of approx-imately 1-2 metres (Ylla Arb´os et al., 2021; Chowdhury et al., 2023). This erosion leads to various problems such as instability of struc-tures or disruption to shipping. To address this ongoing degradation, a potential solution is the implementation of...abstract 2024

Ylla Arbos, C. (author), Schielen, R.M.J. (author), van Vuren, Saskia (author), Snoek, Yvo (author), Blom, A. (author)Channel adjustment in engineered rivers is often associated with channel bed incision (e.g., Chowdhury et al., 2023, Czapiga et al., 2022a, 2022b, Ylla Arbós et al., 2021). Channel bed incision reduces the stability of in-river structures, exposes river-crossing cables and pipelines, and the spatial variability of channel bed incision due to...abstract 2024

(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.

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 Bergen, J. (author)Sandy shores around the world suffer from coastal erosion due to land subsidence, a lack of sediment input and sea level rise. This often leads to the construction of hard structures, such as sea walls and breakwaters, that consolidate the coastal zone but disrupt the dynamic system of coastal deltas. To compensate for coastal erosion in a more...doctoral thesis 2023

Wijsman, Jeroen W.M. (author), Prins, Theo C. (author), Moons, J. J.Simeon (author), Herman, P.M.J. (author)Sand nourishment is a widespread management strategy to protect sandy coasts against erosion. Nourishments can impact the benthic fauna directly by burial and indirectly by changing environmental conditions such as bottom shear stress and/or sediment composition (grain size distribution). The macrobenthic community in soft-bottom environments...journal article 2023

Ribas, Francesca (author), Portos-Amill, Laura (author), Falqués, Albert (author), Arriaga, Jaime (author), Marcos, Marta (author), Ruessink, Gerben (author)Mean sea-level rise (MSLR) will induce shoreline recession, increasing the stress on coastal systems of high socio-economic and environmental values. Localized mega-nourishments are meant to alleviate erosion problems by diffusing alongshore over decades and thus feeding adjacent beaches. The 21-st century morphological evolution of the...journal article 2023

Dutch experience with sand nourishments for dynamic coastline conservation – An operational overviewBrand, Evelien (author), Ramaekers, Gemma (author), Lodder, Q.J. (author)The Dutch coast is one of the most heavily nourished coasts globally. An average of 12 mln. m3 is annually added to the coastline of only 432 km for dynamic coastline conservation. This study provides an overview of the operational aspects of the more than 300 nourishments for coastline maintenance that have been performed since the 1990s and...journal article 2022

Lodder, Q.J. (author), Huismans, Y. (author), Elias, Edwin (author), de Looff, Harry (author), Wang, Zhengbing (author)The sediment exchange between the Dutch Wadden Sea and the North Sea coastal zone is of key importance to Dutch coastal management. Net sediment import from the coastal zone to the Wadden Sea results in coastal erosion which needs to be compensated through nourishments. At the same time net sediment import is the source of sediment for 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

Wijsman, Jeroen W.M. (author), Craeymeersch, Johan A. (author), Herman, P.M.J. (author)Epifauna and infauna are often sampled by different types of sampling devices including grabs, and dredges, depending on various factors such as local environmental conditions, research questions and available budget. Because grabs and dredges have a different species-specific selectivity, both methods could be complementary but for some...journal article 2022

(author), Wang, Zhengbing (author), van Prooijen, Bram (author)Estuaries and coasts can be conceptualized as connected networks of water and sediment fluxes. These dynamic geomorphic systems are governed by waves, tides, wind, and river input, and evolve according to complex nonlinear transport processes. To predict their evolution, we need to better understand the pathways that sediment takes from source...conference paper 2021

(author)Sandy shores worldwide suffer from coastal erosion due to a lack of sediment input and sea-level rise. In response, coastal sand nourishments are executed using ‘Building with Nature’ techniques (BwN), in which the sand balance is amplified and natural dynamics are instrumental in the redistribution of sand, cross- and alongshore. These...journal article 2021

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

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
