Colina Alonso, A. (author)The world’s coasts and deltas offer a multitude of valuable ecosystem services, providing safety against flooding and economic benefits. Many of these systems are, however, under pressure by climate change and increasing human activities. Protecting these systems and preservation of their multiple functions requires a thorough understanding of...doctoral thesis 2024

van Westen, B. (author), Luijendijk, Arjen (author), de Vries, S. (author), Cohn, Nicholas (author), Leijnse, Tim W.B. (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

Colina Alonso, A. (author), van Maren, D.S. (author), Oost, Albert Peter (author), Esselink, Peter (author), Lepper, Robert (author), Kösters, Frank (author), Bartholdy, Jesper (author), Bijleveld, Allert (author), Wang, Zhengbing (author)The world’s coasts and deltas are progressively threatened by climate change and human activities. The degree at which coastlines can adapt to these changes strongly depends on the sediment availability. The availability of muddy sediments is however poorly known. This study aims at developing a mud budget for the world’s largest system of...journal article 2024

van Denderen, R. Pepijn (author), Schielen, R.M.J. (author), Paarlberg, Andries J. (author), Reneerkens, Michiel (author), Augustijn, Denie C. M. (author)Local river interventions, such as channel narrowing or side channels, are often necessary to maintain safety, ecology, or navigation. Such interventions have different effects on the river's bed morphology during periods of high- and low-discharge events. Mapping the bed-level variations for different discharge levels and understanding these...journal article 2024

Ton, A.M. (author)Sandy foreshores, beaches and dunes play an eminent role in flood risk reduction in coastal areas, reducing the impact of wind waves and storm surges on the hinterland. In some areas, sandy protection is naturally present. In other coastal areas, engineering solutions are needed to provide safety. “Soft” sediment-based solutions often serve...doctoral thesis 2023

Deng, X. (author)Tidal inlet systems, which consist of back–barrier basins connected to the open sea by one or multiple inlets, are found at many places along sandy coasts. They are valuable for ecology (breeding and feeding areas), economy (gas–mining and sand–mining) and recreation, and are important for coastal safety. But they are also sensitive to external...doctoral thesis 2023

(author), Taal, Marcel (author), van der Werf, Jebbe (author)In the Western Scheldt estuary, like in many estuaries, safe navigation, flood protection, and ecological targets require a balanced and sustainable sediment management. A thorough understanding of the morphodynamic functioning of the estuary and its response to changes in hydrodynamics (natural sediment transport) and large-scale interventions...review 2023

Schrijvershof, R. A. (author), van Maren, D.S. (author), Torfs, P. J. J. F. (author), Hoitink, A. J. F. (author)Existing tidal input reduction approaches applied in accelerated morphodynamic simulations aim to capture the dominant tidal forces in a single or double representative tidal cycle, often referred to as a “morphological tide.” These strongly simplified tidal signals fail to represent the tidal extremes and hence poorly allow to represent...journal article 2023

Strijker, B. (author), Asselman, Nathalie (author), de Jong, Jurjen (author), Barneveld, Hermjan (author)In July of 2021, large areas in the catchment of the Meuse River in Belgium, the Netherlands and Germany were affected by extreme rainfall and floods. This paper presents the hydraulic and morphological data that were collected during and after the flood. The data were analysed to understand the hydraulic and morphological functioning of the...journal article 2023

(author), Measures, Richard (author)Bank erosion plays an important role in the hydro-morphodynamics and evolution of natural rivers. Therefore, it is essential to have a reliable bank erosion model for accurate simulation of hydro-morphodynamic processes. We developed and successfully implemented a new, feasible bank erosion model in Delft3D software. The developed model...journal article 2023

(author), Wang, Zhengbing (author)The morphology of tide-dominated systems is progressively influenced by human activities and climate change. Quantitative approaches aiming at understanding or forecasting the effects of interventions and climate change are often aggregated, thereby simplifying or schematizing the investigated area. In this work, we advance on the knowledge...journal article 2023

Li, Jiaguang (author), van der Vegt, Helena (author), Storms, J.E.A. (author), Tooth, Stephen (author)Crevasse splays generate subtle local relief and contribute to fluvial basin sedimentary filling but controls on splay development along dryland rivers remain poorly understood owing to limited field, laboratory, and numerical modelling studies.

Ton, A.M. (author), Vuik, V. (author), Aarninkhof, S.G.J. (author)Low-energy, non-tidal lake beaches are known to be subject to longshore morphodynamics, but little is known about how they are driven by wind and wave-driven currents. Lake Markermeer is a shallow (∼4 m deep), wind-dominated lake, of approximately 700 km<sup>2</sup>. A gradient in wind-induced water level set-up at the leeward shore induces a...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

Tas, S.A.J. (author)Over the last decades, mangrove forests have suffered immense and rapid losses worldwide. In recognition of their important socio-economic and environmental functions, many attempts have been made to both protect the remaining mangrove coastlines and restore eroding sites. Unfortunately, many rehabilitation attempts have failed, lacking a...doctoral thesis 2022

Pearson, S.G. (author)In an era of rising seas and other challenges posed by climate change, coastal regions like the Netherlands are facing ever graver threats. Strategic sand nourishments could mitigate the threat of coastal erosion and sea level rise on barrier island coasts while limiting ecological impacts. However, insufficient knowledge of sediment transport...doctoral thesis 2022

In this paper, we explore the cross-shore dynamics of cheniers in their ‘active’ phase, i.e. the phase between their formation and their landing on the shore and can no longer be reached by daily wave and tidal influences. While cheniers described in...journal article 2022

(author)The river bed level in low-land rivers like the Rhine branches in The Netherlands changes continuously on various spatial and temporal scales. Large-scale degradation occurs in many rivers due to river-wide engineering interventions, such as channelization, in the last decades and centuries. Local river interventions, such as the construction...journal article 2022
