Laboratory experiments evaluate scour behavior related to wing wall and canal slope configurations, suggesting engineering solutions for sustainable structures.
Key Points
This study investigates the effects of combined wing wall geometry and canal inside slope on scour behavior for improved water structure design.
Conducted 435 laboratory experiments using a physical model under varying discharge conditions.
Tested common canal inside slopes with four types of wing walls.
Measured and analyzed scour hole geometry including depth, length, and shape.
The splayed wing wall configuration reduced maximum scour depth by approximately 22.74% and length by 23.61% compared to box type at a 1:1 canal inside slope.
Developed new dimensionless empirical equations to predict downstream scour behavior.
