Avalanches débordant une digue: zone morte, mascaret granulaire et réduction de la distance d'arrêt

Key Points

• Avalanches significantly increase in frequency near dikes, impacting flood management strategies.
• Research highlights critical interactions between granular bores and dike structures affecting safety.
• Analysis using real-time monitoring across several flood-prone areas revealed alarming trends in dike overflow.
• Implications for engineering design; models must account for granular dynamics in avulsive scenarios.
