Low permeable soil
WebPermeable pavements are an important mitigation strategy for urban flooding. These highly porous materials rapidly drain surface water, enabling storm water to pass through otherwise impermeable infrastructure. However, conventional permeable pavements are prone to clogging, degrading their performance and service life [1-10]. WebFor example, a sandy soil will have a permeable rate of 0.5 to 1.0 millimeters per second (mm/s), while a fine-grained soil with a high clay content (e.g., clay loam) may have an …
