Afflux in bridge engineering refers to:

• Vertical clearance
• Erosion at base
• Upstream water rise due to bridge obstruction

Answer explanation

Afflux is the rise in upstream water level due to bridge-induced obstruction.

Which classification does a bridge with deck slab on top of girders fall under?

• Through bridge
• Deck bridge
• Semi-through bridge
• Viaduct bridge
