Superimposed bedforms in the Rhine-Meuse delta

13/02/2020 - Rivers2Morrow
This research aims to elucidate the role of superimposed bedforms in rivers and to determine whether superimposed bedforms contribute to the transport of bed sediment and how they interact with primary dunes.

Subsite Abstract

Towards a model for river dune dynamics under high and low discharges

13/02/2020 - Rivers2Morrow
The interplay of bedform dynamics, especially river dunes, and extreme flow conditions results in multiple challenges in river management. Decreasing this uncertainty results in more certain flood levels and therefore increases water safety.

Subsite Abstract

The initial morphological impact of the longitudinal dams

van Denderen, R. P., Kater, E., Jans, L. H., & Schielen, R. M. J. - 13/02/2020 - RiverCare
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.

The sensitivity of a dike-marsh system to sea-level rise

Marijnissen, R., Kok, M., Kroeze, C., & van Loon-Steensma, J. - 10/01/2020 - All-Risk
Model-based exploration of the future need for dike heightening due to: (1) sea-level rise, (2) changes in sediment concentration, (3) a retreat, and (4) compaction of the salt marsh.
