In response to the escalating challenges posed by rapid urbanization, this article conducts a comprehensive exploration of innovative models for urban water management. Through a comparative analysis, we delve into the principles, methodologies, and potential outcomes of three prominent models: the Sustainable Urban Drainage Systems (SUDS), Water-Sensitive City Model (WSUD), and Depression-Infiltration Canal System Model. Each model offers a unique perspective on addressing urban water challenges, emphasizing sustainability, adaptability, and environmental protection. The SUDS model emphasizes replicating natural ecological drainage systems to mitigate urban waterlogging, enhance water quality, and promote sustainable water management practices. Incorporating green infrastructure, natural ecological restoration, and community participation, the WSUD model integrates various aspects of water management to achieve effective utilization and recycling of water resources while enhancing urban resilience. This paper is helpful to promote a more sustainable and flexible future.
