Major river interventions can greatly affect stakeholders and their connection to the river landscape. We show how recreationists’ perceptions of nature and landscape influence their expectations about a pilot intervention in the Waal river.

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.

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.

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.

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.

The river bed continuously changes on various spatial and temporal scales. Migrating river dunes are an example of local and relatively fast change. At the same time, engineering measures from the last decades cause the river bed to degrade to the present date. To be able to predict the development of the river bed, it is important to distinguish between and disentangle the various spatial and temporal scales.
