The study deals with the investigation of flow structures in groyne fields interacting with the flow generated by navigation. Groynes are traditionally constructed to ensure adequate water depth for navigation, so the interaction of navigation and groyne fields is nearly guaranteed. The Hungarian Danube section – which is part of the 7th...

The objective of this study is to make a study on dealing with uncertainty in the design of river training works. Based on this study, a method and several instruments have been developed that aim to improve a full and consistent use of a probabilistic design approach. This study is divided into three parts. The outline is rather unconventional...

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...

The dynamic nature of braided rivers can lead to river bank erosion, bankline shifts and navigational hindrance. River training measures can be implemented in order to mitigate these problems. An alternative to conventional river training works is the closure of a channel within the braided network. Until recent there has been no systematic...

In een rivierbocht treedt een zogenaamde spiraalstroming op, waardoor het typische dwarsprofiel van een rivierbocht ontstaat: diep in de buitenbocht en ondiep in de binnenbocht. Hierdoor is slechts over een kleine breedte voldoende vaardiepte aanwezig en vormen bochten in de Waal een knelpunt in de rivier voor de scheepvaart. In het Waalproject...

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...

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...

In this report a study is carried out on the Magdalena River near the village of San Pablo, Colombia. The Magdalena River near San Pablo experiences two major issues which are related to navigation and erosion. The major problem for inland navigation is the sharp bend of the Magdalena River at San Pablo, which has too small a radius, causing...
