Chowdhury, M. Kifayath (author), Blom, A. (author), Ylla Arbos, C. (author), Schielen, R.M.J. (author)Climate change is responsible for global shifts in precipitation patterns and an overall in-crease in global temperatures. The transi-tions are anticipated to modify the river hydro-graph and sea level. The changes to the hy-drograph are also likely to influence sediment flux. These alterations imply shifts in both up-stream and downstream...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

Wilson, Stanford (author), Rem, Nils (author), Schielen, R.M.J. (author), Snoek, Yvo (author)River managers today are faced with the challenge of adapting to climate change while also having to sustainably secure all important functions in a healthy river system for society. Nature-based Solutions (NbS) have proven themselves effective across a multitude of contexts; providing integrative approaches for river restoration, conservation...abstract 2024

Spriggs, A.M.S. (author), Mosselman, E. (author), Schielen, R.M.J. (author), Stancanelli, L.M. (author)Recent policy initiatives in Europe emphasize a movement towards nature-based solutions in flood management; however, a quantitative relationship between specific flood management measures and indicators of ecological health and biodiversity is difficult to establish (Penning et al., 2023). In the Netherlands, several studies have been conducted...abstract 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

Ylla Arbos, C. (author), Blom, A. (author), White, S. R. (author), Patzwahl, R. (author), Schielen, R.M.J. (author)Erosion-control measures in rivers aim to provide sufficient navigation width, reduce local erosion, or to protect neighboring communities from flooding. These measures are typically devised to solve a local problem. However, local channel modifications trigger a large-scale channel response in the form of migrating bed level and sediment...journal article 2024

Chowdhury, M. Kifayath (author), Blom, A. (author), Ylla Arbos, C. (author), Verbeek, Merel C. (author), Schropp, Max H.I. (author), Schielen, R.M.J. (author)A bifurcation in an engineered river system (i.e., fixed planform and width) has fewer degrees of freedom in its response to interventions and natural changes than a natural bifurcation system. Our objective is to provide insight into how a bifurcation in an engineered river responds to peak flows and human interventions. To this end, we analyze...journal article 2023

Blom, A. (author), Schielen, R.M.J. (author)Typically the time scale of river response to change of the controls (i.e., flow duration curve, sediment flux, and sea level) is of the order of decades to centuries. Understanding temporal change and, in particular, abrupt change in channel response is increasingly important in engineered river systems, as abrupt change may negatively affect...abstract 2023

Chowdhury, M. Kifayath (author), Blom, A. (author), Ylla Arbos, C. (author), Schielen, R.M.J. (author)River bifurcations divide the water and sediment over two downstream branches or bifurcates. As the changing climate adjusts the boundary conditions (i.e., base level, hydrograph, and sediment flux) for bifurcations, it will affect their flow and sediment partitioning over the bifurcates. Our objective is to provide insight into the response of...abstract 2023

Ylla Arbos, C. (author), Blom, A. (author), Sloff, C.J. (author), Schielen, R.M.J. (author)Climate change puts pressure on river systems, as it increasingly alters the river controls. Engineered rivers with a fixed planform respond to climate change and human intervention by adjusting the channel slope and bed surface grain size distribution. This response often consists of channel bed incision, over hundreds of kilometres, and during...abstract 2023

Ylla Arbos, C. (author), Blom, A. (author), Sloff, C.J. (author), Schielen, R.M.J. (author)Human intervention makes river channels adjust their slope and bed surface grain size as they transition to a new equilibrium state in response to engineering measures. Climate change alters the river controls through hydrograph changes and sea level rise. We assess how channel response to climate change compares to channel response to human...journal article 2023

(author)Sediment transport capacity and supply of sediment to a river channel increase significantly during peak flow events. Here we study how a river bifurcation system (partitioning water and sediment over its downstream branches) responds to peak flow events.

van Denderen, R. Pepijn (author), Kater, Emiel (author), Jans, Luc H. (author), Schielen, R.M.J. (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
