Laying bare systemic river bed changes in the river Rhine
It is important to link cause-and-effect relations between bed response and their dominating triggers. This is particularly important in highly-engineered navigable rivers, where multiple influences from close-by and further away can obscure the dominating causes of local bed level changes, and thereby possibly point in the wrong direction when it comes to sustainable river management practices.

A characterization of side channel development
Side channel generally aggrade. The rate at this occurs depends on the design of the side channel. We propose three categeories of side channels which can be used to estimate the time scale of side channel development

Residual Biomass: A Silver Bullet to Ensure a Sustainable Bioeconomy?
Using residual biomass, such as grass and wood chips, as a resource instead of treating it as waste is not automatically more sustainable.

The initial morphological impact of the longitudinal dams
Human interventions can result in changes in the equilibrium profile of rivers. It is difficult to identify the bed level changes that result from river interventions due to the various causes of bed level changes. Using wavelet filtering, we are able to isolate the effect of river interventions based on the length scale over which they occur. The method presented here can aid in verifying model results. In addition, it can be used to estimate bed level changes that occur over various spatial scales.

Ill posedness in modelling two-dimensional morphodynamic problems
We reveal the existence of two additional mechanisms under which the 2D system of equations does not provide a unique solution.

Morphodynamic assessment of side channel systems using a simple one-dimensional bifurcation model and a comparison with aerial images
To aid the future design and maintenance, a set of diagrams allow to estimate both the equilibrium state and the time that takes for the bed load of the main channel to aggrade or deposit in the side channel.

Low-hanging fruits in large-scale fluvial landscaping measures
We show that the multidimensional evaluation of river interventions in the Waal river opens up opportunities to discuss possible trade-offs.
