Urban drainage systems face significant challenges due to increased urbanization and climate change, leading to higher runoff volumes, peak flows, and water pollution. This study evaluates the efficiency of green infrastructure (GI) solutions, including green roofs, permeable pavements, bioretention cells, and urban wetlands, in mitigating these issues. Using a mixed-methods approach, we conducted a comprehensive literature review, field data collection in two urban sites with different climatic conditions, and computational modeling with the Storm Water Management Model (SWMM). The results demonstrate that GI practices significantly reduce runoff volumes, peak flow rates, and pollutant loads. Permeable pavements achieved the highest runoff reduction, particularly in semi-arid climates, while bioretention cells and urban wetlands excelled in pollutant removal. Despite these benefits, challenges such as maintenance requirements and public awareness need to be addressed for successful implementation. This study provides valuable insights for urban planners and policymakers, emphasizing the importance of strategic GI integration for sustainable and resilient urban drainage systems.
