Analyzing natural bed-level dynamics to mitigate the morphological impact of river interventions

Local river interventions, such as channel narrowing or side channels, are often necessary to maintain safety, ecology, or navigation. Such interventions have different effects on the river's bed morphology during periods of high- and low-discharge events. Mapping the bed-level variations for different discharge levels and understanding these...

The long-term response of rivers to engineering works and climate change

Rivers respond to changes in their geometry or their controls in various ways and at a wide range of space and time scales. The response consists of changes in properties such as cross-sectional shape and area, slope, planform pattern, bed roughness and bed sediment composition. Usually, attention for the morphological impact of engineering...

Moveable flood barriers in the Rhine-Meuse estuary

It is possible to reduce flood risk in estuaries without having to drastically modify the river banks by levees or to block shipping routes and ecological flows by dams. ‘Storm surge barriers’ close off a river mouth at times of high sea water levels, but keep the river open during calmer times. ‘Moveable river flood barriers’ direct a river...

How the Dutch plan to stay dry over the next Century

Over two-thirds of the Netherlands’ economy and half its population is below sea level. The Dutch government recently set out far-reaching recommendations on how to keep the country flood-proof over the next century given the likelihood of rising sea levels and river flows. This paper explains the recommendations, which are based on a gradual...

Effects of river floodplain lowering and vegetation cover

The current river management policy in the Netherlands is to give rivers more space, mainly by main channel widening and floodplain lowering. The aim is to reduce flood water levels and to create more favourable conditions for river ecology. However, the effect on water levels gradually disappears due to sedimentation and vegetation growth on...
