Open-Channel Experiments on the Hydraulic Properties of Side-Inflow Pavements Under Lateral Overflow

Key Points

• The research aims to understand how flow characteristics affect hydraulic performance in side-inflow pavements.
• Conducted open-channel experiments with side-inflow pavements under controlled conditions.
• Used glass beads to simulate granular pavement material at drainage openings.
• Analyzed flow rate variations based on changes in side gutter water depth and flow velocity.
• Increased gutter water depth significantly raises flow rates into the pavement.
• An increase in gutter flow velocity leads to reduced flow rates into the pavement.
• Derived experimental equations relate Froude number to flow rates for design purposes.
