Our dike breaching research published in WRR

Overtopping of fluvial dikes (or levees) can lead to the failure of the dike and massive flooding in the protected areas. Flood risk management requires accurate predictions of the breach expansion and of the flow through the breach. Existing methods are limited to frontal dikes (embankment dams) and do not apply for fluvial dikes.

To fill this knowledge gap, an experimental program was conducted in our lab and at EDF-R&D (Chatou, France). Measurements included continuous scanning of the dike geometry using a non-intrusive method (Laser Profilometry Technique), which was developed specifically for this research.

Two recent papers published in Water Resources Research detail the main findings of this experimental research:
