River training and river restoration often imply modifying the patterns and dimensions of bars, channels, and pools. Research since the 1980s has greatly advanced and matured our knowledge on the formation and behavior of river bars, thanks to field work, laboratory experiments, theoretical analyses, and numerical modelling by several research...

The Dutch River Waal, a branch of the Rhine, has been trained for centuries to mitigate the effects of ice-jams and improve navigation. The works, started in 1850, involved river straightening and narrowing by a series of transverse groynes. Besides fulfilling their goal, the groynes also created the need to raise flood protection works and...

Longitudinal training walls are man-made river dividers. They were built in the Netherlands as a replacement of perpendicular groynes as a river training alternative to decrease flood risk and stop the ongoing bed degradation, while still allowing safe navigation. The efficiency of these structures relies on the long-term stability of the two...

This study analyzes and compares data for interventions (river training works, dredging and nourishment), discharge statistics, bed elevation and slope spatially and temporally in the Niederrhein, Bovenrijn, Pannerdensch Kanaal and Waal branches. River training works have actively taken place in the study area so far. Meander cutoffs and...

Braiding rivers are characterised as highly dynamic, and experience annual morphological changes in plan- form. This dynamic nature of the river leads to navigational hindrance and risk of unstable bifurcation points where discharge distributions might switch. In pilot studies, porcupines have shown promising results in re- tarding the flow and...

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 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...

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...

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...

In deze publicatie worden enkele resultaten van projecten in Bangladesh gepresenteerd met aandacht voor een mogelijke toepassing in alternatieve ontwerpen van kribben. Deze resultaten betreffen hoofdzakelijk doorlatende palenrijen en falling aprons. Een falling apron kan worden vergeleken met een toplaag zonder zinkstuk.

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...

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 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...

A study of the applicability and design of spur-type flow-control and streambank stabilization structures has been conducted to establish design guidelines and other criteria for the use of spurs. The recommendations and findings are based on a thorough review of pertinent literature, analysis of several hundred field sites, and on a recent...
