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.

Ill-posedness in modeling mixed sediment river morphodynamics
Our aim is to provide modelers of river morphodynamics with the mathematical tools to detect the occurrence of ill-posedness in their results.

A characterization of side channel development
Side channel generally aggrade. The rate at this occurs depends on the design of the side channel. We propose three categeories of side channels which can be used to estimate the time scale of side channel development

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.

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.

Insight into the local bed-level dynamics to assist management of multi-funtional rivers
River discharge fluctuations cause bed-level variations at various scales, resulting from spatial gradients in the river’s geometry. Insight into these bed-level variations and their relation to discharge fluctuations can help to predict and prevent the formation of local bottlenecks. In this paper, we use bi-weekly bed-level measurements of the river Waal to estimate the bed-level variations related to the river discharge.

Morphological patterns at the intake of a side channel over an oblique sill
Qualitative comparison of the river bed dynamics in the side channel of the longitudinal dam and the flat bed conditions in the scale model at low water level.

Disentangling spatial scales of morphological development
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.

Ill posedness in modelling two-dimensional morphodynamic problems
We reveal the existence of two additional mechanisms under which the 2D system of equations does not provide a unique solution.
