Urbanization and climate change have significantly increased the pressure on cities to adopt resilient stormwater management strategies. Melbourne, Australia, is no exception. As the city expands, managing stormwater runoff, mitigating flood risks, and enhancing water quality have become critical challenges. This thesis presents a comparative study of three contemporary stormwater management strategies: Low Impact Development (LID), Sustainable Urban Drainage Systems (SuDS), and the Sponge City concept. The thesis integrates quantitative data analysis with case studies to evaluate the effectiveness of these strategies in Melbourne. Key findings reveal that while each strategy offers unique benefits, their efficacy is highly context-dependent. LID practices, such as green roofs and permeable pavements, significantly reduce surface runoff in densely built areas.
