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.

Predicting effects of ship-induced changes in flow velocity on native and alien molluscs in the littoral zone of lowland rivers
Shipping increases local flow velocities thereby potentially decreasing species richness of freshwater mussels and snails which in turn affects ecosystem functioning and services.

Analyzing collaborative governance through Social Network Analysis
We mapped the connections between organizations involved in flood protection and nature management in the Waal River and explored the consequences of abolishing the central actor in these networks.

A stakeholder’s evaluation of collaborative processes for maintaining multi-functional floodplains: a Dutch case study
Oblique aggradation: a novel explanation for sinuosity of low‐energy streams in peat‐filled valley systems
We inform stream restoration in peat-filled valleys by looking at the relative position of the erodible material to explain the origin of the stream bends in the Drentsche Aa area.

Users’ perspectives about the potential usefulness of online storylines to communicate river research to a multi-disciplinary audience
This was the first and exploratory step on our initiative of using storylines for science communication. Researchers and practitioners think that stories of science that include facts could be useful!

Rivierbodemdynamiek meenemen in het ontwerp van maatregelen
In the Dutch Waal river, the bed topography of the navigational channel is measured bi-weekly. In a so-called TKI-project (cooperation between Rijkswaterstaat, HKV and Twente University) we use this data to link morphological changes to specific interventions in the river. This is not a straightforward as it may seem, because the morphological changes are the sum of small scale changes due to e.g. the presence of groynes, medium scale changes coming from the intervention and large scale changes coming from engineering measures in the (far) past to which the profile is still adjusting. A so-called wavelet analysis can be used to disentangle these different scales and enables us to focus only on the morphological changes due to the intervention. This improves river operations and maintenance and in the future also to facilitate the planning of new measures to minimize morphological impact.
