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.

The initial morphological impact of the longitudinal dams

Human interventions can result in changes in the equilibrium profile of rivers. It is difficult to identify the bed level changes that result from river interventions due to the various causes of bed level changes. Using wavelet filtering, we are able to isolate the effect of river interventions based on the length scale over which they occur. The method presented here can aid in verifying model results. In addition, it can be used to estimate bed level changes that occur over various spatial scales.

Oblique aggradation: a novel explanation for sinuosity of low‐energy streams in peat‐filled valley systems

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.

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.

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
