Trends in suspended sediment fluxes across the Rhine river basin (1997-2014)
In this study, we aim to quantify the temporal and downstream changes in annual loads of suspended sediments in the Rhine river basin during the past decades to identify major sources and sinks of sediment.

Historic narrowing and deepening of the Rhine-Meuse estuary causes long term sediment deprivation
In this research, we trace this history of human influence on the channels and morphology of the RMD including embanking, land reclamation, dredg- ing and major engineering constructions which have created an urban delta.

Competition and interaction between two bedform scales in the Dutch river Waal
Current work focusses on understanding the competition and interaction between primary and secondary bedforms in a lowland river, based on a large, multi-year dataset of bed elevation scans as well as a dedicated field campaign that maps the dynamics of both primary and secondary dunes.

Channel Bed Erosion Characteristics in the Upper Dutch Rhine Bifurcation Region
This abstract focuses on the local channel bed erosion characteristics at the Upper Dutch Rhine bifurcation area. The knowledge can be used to signal trends in the partitioning of water and sediment and prepare mitigation measures to maintain a safe situation.

Residual sediment transport in a stratified estuarine channel
Based on field measurements and sediment transport modelling, we aim to unravel the mechanisms controlling residual sediment fluxes in highly stratified estuarine channels, by focusing on the New Waterway.

Mid-Century Channel Response to Climate Change in the Lower Rhine River
The goal of this study is to assess how channel response to climate- related changes in the river controls compares to channel response due to (future) human intervention, focusing on changes in channel bed elevation, bed slope, and bed surface grain size over the next century.

Massive morphological changes during the 2021 summer flood in the River Meuse
The objective of the study was to improve understanding of the morphological processes during extreme floods, by focusing on the Common Meuse. Here, the riverbed surface is composed of gravel and the longitudinal bed slope is five times steeper than the downstream canalized river.

Modelling strategies for low flow dune behaviour
A dune development model that may be used for predicting dunes must be able to simulate dune behaviour for both high and low flows well.

Efficient long-term one-dimensional morphodynamic modelling in alluvial rivers using simplified models – theory and validation
The scope of this research is to assess how and when model simplifications are possible, without jeopardizing the predictive capacity in terms of sediment transport and riverbed development.

Scenarios for Controls of River Response to Climate Change in the Lower Rhine River
We discuss the projected changes of the hydrodynamic river controls over the 21st century, and how they can be transformed into suitable boundary conditions for a schematized model. Here we consider the Lower Rhine River, from Bonn (Germany) to Gorinchem (Netherlands).
