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.

Change from a laterally stable to meandering river – a reconstruction of the historical discharge
We show how the Overijsselse Vecht river changed from a laterally stable to a meandering river ca. 500 years ago and further developed a methodology to reconstruct the historical discharge.

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.

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.

Explaining artificial side channel dynamics using data analysis and model calculations
We studied in detail the development of a side channel in the river Waal. A more frequently flowing side channel results in lower aggradation or sedimentation.
