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.

Exploring place attachment and visions of nature, of water-based recreationists
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.

The role of place attachment in public perceptions of a re-landscaping intervention in the river Waal
Public perception research can tell you more about the importance of river landscapes as ‘space’ and ‘place’.

Uncertainty obscures Room for the River results for now
Models predict water level decrease, but measurements are too uncertain for now. This reveals a challenge for validation model predictions of human intervention

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.

Quantifying biomass production for assessing ecosystem services of riverine landscapes
An approach for quantifying the changes in the biomass growth over the Dutch Rhine tributaries due to the river interventions and floodplain vegetation management between the years 1997 and 2012.

View details View publicationUsers’ 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!
