| Summary: | Stormwater management poses a significant challenge in urbanized regions, particularly in areas prone to flash flooding. This study evaluates the potential of geopolymer pervious concrete pavement (PCP) as an innovative sustainable drainage system (SUDS) to mitigate stormwater impacts. With its highly permeable structure, geopolymer PCP enhances infiltration, reduces runoff intensity, and minimizes flooding risks, making it a promising solution for urban flood management. The research integrates laboratory testing with real-world analysis, utilizing advanced geographic information system (GIS) tools and hydrological modeling techniques. A case study was conducted at the UAE University Campus, covering an area of approximately 1.26 km<sup>2</sup>. This analysis focused on an extreme rainfall event that occurred from April 15th and 16th, 2024, which recorded a total of 168 mm of precipitation. The study simulated rainfall-runoff dynamics under baseline conditions and compared them to scenarios incorporating geopolymer PCP in urban infrastructure elements, such as sidewalks, parking lots, and road shoulders, to evaluate the effectiveness of the lab-tested PCP.</p>
<p>Hydrological modeling, conducted using PCSWMM, demonstrated significant benefits of geopolymer PCP. Results showed a 20% reduction in peak flow at the outlet compared to baseline conditions, preventing stormwater pipes from reaching full capacity and enabling the optimization of stormwater infrastructure, including the use of smaller pipe diameters. Additionally, spatial analyses revealed substantial reductions in flooded areas, reinforcing the viability of PCP as an effective solution for managing urban stormwater. This innovative approach bridges the gap between laboratory research and practical applications, showcasing the transformative potential of geopolymer PCP in addressing urban flooding challenges. |
