Can Linear Stability Analyses Predict the Development of Riverbed Waves With Lengths Much Larger Than the Water Depth?

03/03/2023 - Rivers2Morrow
In this paper we evaluate the use of analytical relations, based on linear stability analyses of the St. Venant-Exner equations, as rapid assessment tool for migration and damping of large riverbed waves. Supported by numerical simulations with a 1-D numerical model (markers in chart below) we prove that for Froude numbers ≤ 0.3 the results from linear stability analysis are valid for predicting the propagation of low riverbed waves. For larger Froude numbers riverbed waves are more diffusive and migrate slower in time than predicted from linear stability analysis.

Effecten van zeespiegelstijging op baggeren en riviermondingmorfologie

05/10/2022 - Rivers2Morrow
Aan de hand van schaalexperimenten, empirische relaties en praktijkvoorbeelden van riviermondingen en delta's wereldwijd, stellen wij vast dat baggeren en SLR samen de bochtmigratie versterken, terwijl SLR alleen leidt tot decentralisatie van kanalen en verdrinking van het intergetijdengebied.

Effects of Sea-Level Rise on Dredging and Dredged Estuary Morphology

05/10/2022 - Rivers2Morrow
Using scale experiments, empirical relations and real world examples from global estuaries and deltas, we identify that dredging and SLR combined enhance bend migration whereas SLR alone leads to decentralizing of channels and drowning of intertidal area.

Sediment deficit and morphological change of the Rhine–Meuse river mouth attributed to multi-millennial anthropogenic impacts

15/07/2022 - Rivers2Morrow
In this research, we trace the development of one system, the Rhine–Meuse delta in the Netherlands (RMD) from two natural estuaries (the RME fed by the Rhine river and the HVL fed by the Meuse river) to a densely urbanized delta and the effect human activities have had on its morphology through time.
