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.

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.

Understanding actor perspectives regarding challenges for integrated river basin management
People use different world views when addressing problems, often resulting in different views on both the problem and its solution. For this paper, we explored management challenges and actor perspectives on these in Dutch integrated river basin management.

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.
