Embankment breaching is a composite process coupled by hydraulic processes and sediment transport processes. Erosion is the link in the interaction between breach flow and embankment material. Surface erosion starts in the initial breach phase and triggers the initial damage of the embankment. As the surface erosion develops completely, the headcut erosion leads the breaching process by cutting the embankment slope and deepening the crest level finally. The helicoidal erosion undermines thedoi:10.3850/38wc092019-5554 fatcat:xvevfvaiazcdlbkiwva265jlfi
