Sponge cities, pioneered by architect Kongjian Yu, utilize nature-based infrastructure to combat urban flooding, incorporating features like wetlands and permeable pavements. Adopted as national policy in 2013, these systems slow water flow and enhance groundwater recharge, contrasting with costly and rigid traditional drainage solutions. Projects like those in Wuhan show significant cost savings while providing adaptable and effective water management strategies. This article reviews nine projects focused on maximizing soil water absorption and reducing runoff, demonstrating the diverse strategies architects employ to enhance urban resilience against flooding.
The 'sponge city' concept revolutionizes urban water management by promoting nature-based infrastructure, making cities more resilient to flooding through innovative, environmentally friendly designs.
Sponge city projects use ecological systems like wetlands and rain gardens to absorb rainwater, proving more cost-effective and sustainable than traditional concrete drainage solutions.
