The study focuses on using green infrastructure like bioretention to manage stormwater in urban areas. As cities grow, rainwater can't soak into the ground, leading to flooding. Bioretention systems help by letting rainwater filter into the soil, reducing pollution and preventing floods. The researchers tested these systems in experiments to see how well they work. They found that bioretention can help water seep into the ground instead of running off, which can help protect the environment and prevent flooding in urban areas.
