Beselly, S.M. (author), Grueters, U. (author), van Der Wegen, M. (author), Reyns, J.A.H. (author), Dijkstra, J. (author), Roelvink, D. (author)As climate-change-driven extremes potentially make coastal areas more vulnerable, mangroves can help sustainably protect the coasts. There is a substantial understanding of both mangrove dynamics and hydro-morphodynamic processes. However, the knowledge of complex eco-geomorphic interactions with physical-environmental stressors remains...journal article 2023

Schrijvershof, R. A. (author), van Maren, D.S. (author), van der Wegen, M. (author), Hoitink, A.J.F. (author)Deltaic intertidal areas disappear worldwide. This impacts delta morphology, because the extent and physiological character of the tidal floodplains control the tidal regime and, as a result, residual sediment transport patterns. Extensive reclamation of former tidal flats, effectively changing the ratio of channel volume to intertidal storage...abstract 2023

Elmilady, H.M.S.M.A. (author), van der Wegen, M. (author), Roelvink, D. (author), van der Spek, A. (author)Intertidal shoals are key features of estuarine environments worldwide. Climate change poses questions regarding the sustainability of intertidal areas under sea-level rise (SLR). Our work investigates the SLR impact on the long-term morphological evolution of unvegetated intertidal sandy shoals in a constrained channel-shoal system....journal article 2022

Zheng, J. (author), Elmilady, H.M.S.M.A. (author), Röbke, B. R. (author), Taal, M. (author), Wang, Zhengbing (author), van Prooijen, Bram (author), de Vet, P.L.M. (author), van der Wegen, M. (author)Intertidal shoals are pronounced morphological features found in many estuaries worldwide. Apart from maintaining an ecologically unique intertidal environment, shoals also protect adjacent dyke systems by attenuating waves. The fate of sandy shoals under anticipated sea level rise (SLR) scenarios is underexplored. The current research...journal article 2021

Thanh, Vo Quoc (author), Roelvink, D. (author), van der Wegen, M. (author), Reyns, J.A.H. (author), Reyns, Johan (author), Kernkamp, Herman (author), Van Vinh, Giap (author), Thi Phuong Linh, Vo (author)Building high dykes is a common measure of coping with floods and plays an important role in agricultural management in the Vietnamese Mekong Delta. However, the construction of high dykes causes considerable changes in hydrodynamics of the Mekong River. This paper aims to assess the impact of the high-dyke system on water level fluctuations...journal article 2020

Elmilady, H.M.S.M.A. (author), Van Der Wegen, M. (author), Roelvink, D. (author), van der Spek, A. (author)Intertidal shoals are vital components of estuaries. Tides, waves, and sediment supply shape the profile of estuarine shoals. Ensuring their sustainability requires an understanding of how such systems will react to sea level rise (SLR). In contrast to mudflats, sandy shoals have drawn limited attention in research. Inspired by a channel...journal article 2020

Elmilady, H.M.S.M.A. (author), van der Wegen, M. (author), Roelvink, D. (author), Jaffe, B. E. (author)Anticipated sea level rise (SLR) threatens intertidal areas and associated ecosystems in estuaries worldwide. There is a need to develop validated modeling tools to assess the impact of SLR on estuarine morphodynamics. This study explores the morphological impact of SLR on a channel-shoal system in San Pablo Bay, a subembayment of San...journal article 2019

van der Wegen, M. (author), Roelvink, D. (author), Jaffe, B. E. (author)Intertidal mudflats are morphodynamic features present in many estuaries worldwide. Often located between vegetated shores and deep channels they comprise valuable ecosystems and serve to protect the hinterland by attenuating waves. Although mudflats are persistently present on yearly to decadal time scales, little is known on their...journal article 2019

(author), van der Wegen, M. (author)Rising sea levels due to climate change can have severe consequences for coastal populations and ecosystems all around the world. Understanding and projecting sea-level rise is especially important for low-lying countries such as the Netherlands. It is of specific interest for vulnerable ecological and morphodynamic regions, such as the...journal article 2018

Minikowski Achete, F. (author), van der Wegen, M. (author), Roelvink, D. (author), Jaffe, Bruce E. (author)Suspended sediment concentration is an important estuarine health indicator. Estuarine ecosystems rely on the maintenance of habitat conditions, which are changing due to direct human impact and climate change. This study aims to evaluate the impact of climate change relative to engineering measures on estuarine fine sediment dynamics and...journal article 2017

Dam, G. (author), van der Wegen, M. (author), Labeur, R.J. (author), Roelvink, D. (author)We hindcast a 110 year period (1860-1970) of morphodynamic behavior of the Western Scheldt estuary by means of a 2-D, high-resolution, process-based model and compare results to a historically unique bathymetric data set. Initially, the model skill decreases for a few decades. Against common perception, the model skill increases after that to...journal article 2016

(author), Zhang, Changkuan (author)Morphodynamic equilibrium is a widely adopted yet elusive concept in the field of geomorphology of coasts, rivers and estuaries. Based on the Exner equation, an expression of mass conservation of sediment, we distinguish three types of equilibrium defined as static and dynamic, of which two different types exist. Other expressions such as...journal article 2016

Minikowski Achete, F. (author), van der Wegen, M. (author), Roelvink, D. (author), Jaffe, BE (author)In estuaries suspended sediment concentration (SSC) is one of the most important contributors to turbidity, which influences habitat conditions and ecological functions of the system. Sediment dynamics differs depending on sediment supply and hydrodynamic forcing conditions that vary over space and over time. A robust sediment transport model...journal article 2015

Guo, L. (author), Van der Wegen, M. (author), Jay, D.A. (author), Matte, P. (author), Wang, Z.B. (author), Roelvink, J.A. (author), He, Q. (author)River-tide dynamics remain poorly understood, in part because conventional harmonic analysis (HA) does not cope effectively with nonstationary signals. To explore nonstationary behavior of river tides and the modulation effects of river discharge, this work analyzes tidal signals in the Yangtze River estuary using both HA in a nonstationary mode...journal article 2015

Guo, L. (author), Van der Wegen, M. (author), Roelvink, J.A. (author), He, Q. (author)Numerous research efforts have been devoted to understanding estuarine morphodynamics under tidal forcing. However, the impact of river discharge on estuarine morphodynamics is insufficiently examined. Inspired by the Yangtze Estuary, this work explores the morphodynamic impact of river discharge in a 560 km long tidal basin based on a 1-D model...journal article 2014

van der Wegen, M. (author), Guo, J. (author), Jaffe, B.E. (author), van der Spek, A.J.F. (author), Roelvink, J.A. (author)Levees are small elevation ridges found on the edge between channels and shoals. They are known to develop along river channels during floods and along channels in alluvial deep water fans. Levees in tidal environments such as the Waddenzee are less pronounced (with a typical height in the order of 10 cm) and may be recognized by the fact that...conference paper 2012

Burgmeijer, M.A. (author), Verhagen, H.J. (author), Van der Wegen, M. (author)Integrated Coastal Zone Management (ICZM) is an interdisciplinary process by definition. Individual actors in CZM need to cooperate and communicate to come to an optimum management strategy for the coastal zone. Because engineers focus on finding the “best” solution in engineering terms, they often are quite surprised that in the end of the day...conference paper 2011

Van der Wegen, M. (author), Dastgheib, A. (author), Jaffe, B.E. (author), Roelvink, J.A. (author)Applications of process-based morphodynamic models are often constrained by limited availability of data on bed composition, which may have a considerable impact on the modeled morphodynamic development. One may even distinguish a period of “morphodynamic spin-up” in which the model generates the bed level according to some ill-defined initial...journal article 2010

(author)The morphodynamic system in alluvial, coastal plain estuaries is complex and characterized by various timescales and spatial scales. The current research aims to investigate the interaction between these different scales as well as the estuarine morphodynamic evolution. Use is made of a process-based, numerical model describing 2-D shallow water...journal article 2008
