A New Method for Calculating the Volume Capture Ratio of Annual Rainfall (VCRAR) of the Sponge City

Key Points

• The volume capture ratio of annual rainfall is essential for effective water management within sponge cities.
• Calculated ratios can show up to a 25% improvement in water capture compared to traditional methods.
• Assessment involved hydrological modeling to understand rainfall absorption and runoff in urban areas.
• Findings may highlight the potential for better urban drainage systems, contributing to more resilient cities.
