IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

The role of bank erosion in restoration works in gravel-bed rivers
Author : FABIAN FRIEDL(1), VOLKER WEITBRECHT(2) & ROBERT M. BOES(3)
ABSTRACT
Predicting and quantifying bank erosion plays an important role in risk management, for river restoration strategies and to
enhance the understanding of river morphodynamics. The triggering mechanisms for bank erosion, namely hydraulicfluvial
processes and geotechnical mass failures, are influenced by a wide range of factors. Serious progress has been
made in the last decades in understanding the influence of different processes on bank stability. Furthermore, various
numerical models for the prediction of changes of the channel width due to bank erosion were developed. In this paper an
overview of the topic of bank erosion and bank stability in gravel-bed rivers is presented. The most important concepts to
describe fluvial bank erosion in non-cohesive material are discussed. Furthermore, a summary of the state-of-the-art in
numerical modelling is given and the corresponding field data and laboratory experiments are described. Research gaps
are identified, the main limitations of existing models are summarized and ideas for future research are given.
