Abstract : Urban areas across the globe are experiencing increasing challenges associated with stormwater management due to rapid urbanization, impervious surfaces, and changing precipitation patterns driven by climate change. Traditional grey infrastructure, such as pipes and concrete drains, has proven insufficient to address flooding, water quality degradation, and ecosystem loss. Green Infrastructure (GI) has emerged as an innovative and sustainable alternative, incorporating natural processes to reduce runoff, enhance infiltration, and improve water quality. This paper explores the role of GI in urban stormwater management, focusing on techniques such as bioretention systems, green roofs, permeable pavements, and constructed wetlands. The discussion also includes performance evaluation, design considerations, and case studies that highlight the potential of GI in reducing urban flooding and pollution. Furthermore, socio economic and policy perspectives are addressed to emphasize the need for integrated planning and community participation. The findings indicate that GI not only mitigates hydrological and environmental challenges but also delivers Page 76-80 © MANTECH PUBLIATIONS 2016.
