Assessment of the effectiveness of green infrastructure in urban stormwater management

Thesis Abstract

Abstract
Urban stormwater management is a critical aspect of sustainable urban development, particularly in the face of increasing urbanization and climate change impacts. Green infrastructure has emerged as a promising approach to managing stormwater in urban areas, offering multiple benefits such as flood mitigation, water quality improvement, and biodiversity enhancement. This thesis aims to assess the effectiveness of green infrastructure in urban stormwater management through a comprehensive investigation that integrates theoretical concepts, empirical evidence, and practical implications. The study begins with an introduction that sets the context for the research, highlighting the importance of sustainable stormwater management in urban environments. The background of the study provides an overview of the existing literature on green infrastructure and its relevance in addressing stormwater challenges. The problem statement identifies the gaps in current stormwater management practices and the need for more sustainable and resilient solutions. The objectives of the study are to evaluate the performance of green infrastructure in managing stormwater, assess the environmental and socio-economic benefits associated with its implementation, and provide recommendations for enhancing its effectiveness. The limitations of the study are acknowledged, including constraints related to data availability, time, and resources. The scope of the study is defined in terms of the geographical area, types of green infrastructure considered, and the specific aspects of stormwater management analyzed. The significance of the study lies in its potential to contribute to the advancement of sustainable urban stormwater management practices and the promotion of green infrastructure as a viable solution. The structure of the thesis is outlined, detailing the organization of chapters and key sections. Definitions of relevant terms are provided to ensure clarity and consistency in the use of terminology throughout the thesis. Chapter two presents a comprehensive literature review that synthesizes existing knowledge on green infrastructure, urban stormwater management, and related topics. The review covers ten key areas, including the principles of green infrastructure design, the benefits of green roofs and permeable pavements, and the challenges of implementation and maintenance. Chapter three describes the research methodology employed in the study, including the research design, data collection methods, sampling techniques, and data analysis procedures. Eight specific contents are detailed, such as the selection of study sites, assessment criteria for green infrastructure performance, and stakeholder engagement strategies. Chapter four presents a detailed discussion of the findings derived from the research, focusing on the performance of green infrastructure in managing stormwater, the benefits realized, and the challenges encountered. The analysis is supported by empirical data, case studies, and examples to illustrate key points and draw meaningful conclusions. Chapter five concludes the thesis by summarizing the main findings, highlighting the implications for practice and policy, and offering recommendations for future research and implementation. The conclusion emphasizes the importance of integrating green infrastructure into urban stormwater management strategies to enhance resilience, sustainability, and environmental quality. In conclusion, this thesis contributes to the growing body of knowledge on green infrastructure and its role in urban stormwater management. By evaluating the effectiveness of green infrastructure and exploring its potential benefits and challenges, this study aims to inform decision-makers, practitioners, and researchers involved in sustainable urban development and environmental management.
