Assessment of Green Infrastructure Strategies for Urban Stormwater Management in Cities

Thesis Abstract

**Abstract
** Urban stormwater management is a critical aspect of environmental management in cities, with increasing challenges posed by climate change, urbanization, and pollution. This thesis focuses on the assessment of green infrastructure strategies for effective stormwater management in urban areas. The study aims to investigate the feasibility and effectiveness of various green infrastructure approaches in mitigating stormwater issues and enhancing urban sustainability. The research begins with an exploration of the current state of stormwater management in urban areas, highlighting the limitations and challenges faced by traditional gray infrastructure systems. The need for sustainable and nature-based solutions, such as green infrastructure, is emphasized in addressing stormwater runoff, water quality, and urban resilience. Through a comprehensive literature review, ten key green infrastructure strategies are identified and analyzed for their applicability in urban stormwater management. These strategies include green roofs, permeable pavements, rain gardens, bioswales, and constructed wetlands, among others. The review examines the design, performance, benefits, and challenges associated with each green infrastructure approach. The research methodology section outlines the approach taken to assess the selected green infrastructure strategies. The methodology includes data collection, site analysis, modeling, and evaluation criteria to compare the effectiveness of different green infrastructure interventions in managing stormwater in urban settings. Findings from the study reveal the potential of green infrastructure strategies to reduce stormwater runoff, improve water quality, enhance urban biodiversity, and provide multiple co-benefits for cities. The discussion in Chapter Four delves into the implications of these findings, including policy recommendations, cost-benefit analysis, and stakeholder engagement strategies for promoting the adoption of green infrastructure in urban stormwater management. In conclusion, this thesis underscores the significance of green infrastructure as a sustainable and nature-based solution for urban stormwater management. The research contributes to the growing body of knowledge on green infrastructure practices and their role in creating more resilient and livable cities. Recommendations for future research and practical applications of green infrastructure in urban planning and design are provided to guide policymakers, practitioners, and stakeholders in advancing sustainable stormwater management practices in cities.
