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

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

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

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), 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

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

(author), Bijleveld, A. I. (author), Wang, Zhengbing (author)The sediment composition of the seabed governs its mobility, hence determining sediment transport and morphological evolution of estuaries and tidal basins. Bed sediments often consist of mixtures of sand and mud, with spatial gradients in the sand/mud content. This study aims at increasing the understanding of processes driving the sediment...journal article 2022

Mathew, R. (author)This dissertation presents a study of fine sediment transport and morphodynamics in estuarine settings using data from the Lower Passaic River (LPR), located in New Jersey, USA. Originally a relatively shallow system, it has been dredged and deepened for navigation purposes from the late-1800s onwards, along with other modifications such as...doctoral thesis 2021

Guo, Leicheng (author), Xie, Weiming (author), Xu, Fan (author), Wang, Xianye (author), Zhu, C. (author), Meng, Yi (author), Zhang, Weiguo (author), He, Qing (author)Net sediment transport is predominantly seaward in fluvial-dominated estuaries worldwide. However, a distributary branch in the Changjiang Estuary, the North Branch, undergoes net landward sediment transport, which leads to severe channel aggradation. Its controlling mechanism and the role of human activities remain insufficiently understood,...review 2021

Phan, M.H. (author)Coastal retreat problems occur in many deltas over the world. Coastal features are not constant over time and are affected by sea level rise, river runoff, sediment supply, wave and tidal energy, underlying geology and climate. In addition, human activities profoundly influence the coastal processes as a result of changing natural patterns of...doctoral thesis 2020

Cohn, Nicholas (author), Ruggiero, Peter (author), de Vries, S. (author), García-Medina, Gabriel (author)Seasonal variability in wave conditions drive corresponding cycles of erosion and accretion along sandy beaches. Despite the fact that these oscillations are well documented at numerous sites throughout the world, the physical processes driving beach recovery remain poorly understood.

(author)Five years of beach topography data were examined to map the spatio-temporal patterns in beach scarp existence. Data of the Sand Engine were used, a mega scale nourishment implemented in 2011 at the Dutch coast. Topographic data were automatically and manually analyzed to recognize scarps in the dataset.

Stecca, G. (author), Siviglia, A. (author), Blom, A. (author)Sediment of different size are transported in rivers under the action of flow. The first and still most popular sediment continuity model able to deal with mixed sediment is the so-called active layer model proposed by Hirano (1971, 1972). In this paper, we consider the one-dimensional hydromorphodynamic model given by the Saint-Venant equations...journal article 2014
