Planform changes and overbank flow in meandering rivers: The river Allier

In this study the river migration model MIANDRAS has been applied to simulations of the planform changes of the river Allier, a tributary of the river Loire in France. The Allier is a very dynamic and natural river system with braided and meandering river sections. Two meandering reaches of the Allier, located between Varennes-sur-Allier and...

The modelling of submerged vanes: A means of fairway improvement in river bends

Recently submerged vanes have come to the attention of Rijkswaterstaat as an option to ensure a sufficient navigable width and depth for some bends in the main Dutch rivers. The submerged vanes can counteract the spiral flow, thus reducing the typical lateral bed slope in river bends. Model calculations by Delft Hydraulics and Haskoning...
