System-based replacement of hydraulic structures: A study to replace the weirs in the river Meuse

For centuries humanity has been engineering the second largest river system in the Netherlands, the river Meuse system. This resulted in improvements for the shipping and water safety functions, but simultaneously has had a negative impact on other functions of the river Meuse system. Nature and water quality, for example, degraded due to the...

Assessing the functional performance of the Meuse river: The impact of bed developments and an altering discharge regime on future river functioning

The Meuse river facilitates important socio-economic functions. In the light of Integrated River Management (IRM), the question rises whether these functions can be facilitated in future decades (until 2050) as well. The riverbed is expected to degrade over the coming decades, just like in the past century. On top of that, the discharge regime...

Scour holes: A data-driven risk-based analysis for scour holes in the Rhine-Meuse Delta

In the Rhine-Meuse Delta over 100 scour holes are located. Many of these scour holes have dynamic behaviour and are growing in size and depth. A scour hole can lead to an increased probability of flooding. One of the potential hazards of the presence of scour holes is the occurrence of flow slides on the foreshore next to scour holes. Depending...

Long-term morphologic development and the effect on hydraulic load: Scenarios for long-term riverbed development in the main channel of the Dutch Rhine system and their impact on hydraulic load

Assessment of the effects of nourishments on coastal state indicators, using a Bayesian modelling approach

The Dutch coast is affected by coastal erosion. In order to limit erosion and prevent inland migration of dunes, sand nourishments have been adopted as a common practice for the maintenance of the coast. The evaluation of the applied coastal erosion policy is achieved by the use of coastal indicators. Increased number of nourishments affects the...

Hydraulic evaluation of longitudinal training dams

In 2015, the Dutch government initiated the ‘longitudinal training dams pilot project’. With the help of longitudinal dams, a two-channel system is created in which the river is divided into a main and a side channel. A combination of an inlet and several openings between the dams allows water and sediment to be exchanged between the two...
