We show that the multidimensional evaluation of river interventions in the Waal river opens up opportunities to discuss possible trade-offs.

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.

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.

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!
