Channel closure in large sand-bed braided rivers

In large braided rivers, river training is often required to protect the banks against erosion, to improve navigability and for land reclamation. Closing one of the channels is a promising option to achieve these goals. However, there is a lack of systematic research on channel closures and no guidelines for their use exist. In the few...

Experimental research on the effects of surface screens on a mobile bed

In 2000 the Dutch government chose a new point of view for the Dutch rivers: “Room for the River”. This viewpoint is the basis for a new approach of high water protection in the Netherlands. Instead of strengthening and raising the dikes, solutions must be based on space and spatial quality. One of the suggested measures is the addition of...

Onderzoek naar een samengesteld rivierprofiel met dichte kribben

In het geval van dichte kribben, die niet overstroomd worden, wordt er in de kribvakken een neer aangedreven. Deze geleidt de hoofdstroming in de rivier. De neer is alleen stabiel als de kribben niet al te ver van elkaar liggen. De maximale kribafstand waarbij de neer nog net stabiel kan worden genoemd kan worden bepaald met behulp van de...
