Experimental Study on the Scour Suppression Effect of Deposited Gravel Groups During Levee Overtopping

Key Points

• The central aim is to evaluate how deposited gravel groups affect scour suppression during levee overtopping events.
• Conducted experiments on levees during overtopping conditions
• Assessed the impact of gravel deposits on flow velocity
• Evaluated maximum scour depth related to gravel deposition
• Deposited gravel significantly reduced flow velocity, contributing to scour suppression
• Established a qualitative relationship between gravel quantity and maximum scour depth
• Highlighted the need to consider gravel effects in erosion control mechanisms
