“…This suggests that BMPs can play a crucial role in mitigating the impacts of climate change on flood control. This finding is consistent with previous research that supports the importance of implementing BMPs in urban watersheds to decrease the impact of urban flooding [14,[55][56][57][58][59]. The results of a study conducted by Masseroni and Cislaghi 2016 [60] align with our findings, highlighting the substantial benefits of widespread green roof implementation.…”

Floods are amongst the most destructive and costly natural disasters impacting communities around the globe. The severity and reoccurrence of flooding events have been more common in recent years as a result of the changing climate and urbanization. Best Management Practices (BMPs) are commonly used flood management techniques that aim to alleviate flooding and its impacts by capturing surface runoff and promoting infiltration. Recent studies have examined the effectiveness of BMPs in countering the effects of flooding; however, the performance of such strategies still needs to be analyzed for possible future climate change. In this context, this research employs climate model-driven datasets from the North American Regional Climate Change Assessment Program to evaluate the effects of climate change on urban hydrology within a study region by calculating historical and projected 6 h 100-year storm depths. Finally, the climate-induced design storms are simulated in the PCSWMM model, and the three BMP options (i.e., porous pavement, infiltration trench, and green roof) are evaluated to alleviate the impact of flooding events. This study quantifies the impact of changing climate on flood severity based on future climate models. The results indicate that peak discharge and peak volume are projected to increase by a range of 5% to 43% and 8% to 94%, respectively. In addition, the results demonstrated that green roofs, Permeable Pavement, and infiltration trenches help to reduce peak discharge by up to 7%, 14%, and 15% and reduce flood volume by up to 19%, 24%, and 29%, respectively, thereby presenting a promising solution to address the challenges posed by climate change-induced flooding events.

“…In the complex urban landscape, effective pollution mitigation strategies are vital to safeguard water quality and ensure the sustainable use of water resources (Hughes et al, 2014). This section examines two key components of pollution mitigation in urban water: Stormwater Management and Wastewater Treatment (Cooper, et al, 2019;Yang, et al, 2022). Stormwater runoff poses a significant threat to urban water quality as it can carry pollutants such as sediments, nutrients, and chemicals into water bodies (Berland, et al, 2017;Wanielista, and Yousef, 1992;Jefferson et al, 2017).…”

This comprehensive review explores the landscape of Urban Water Management in the United States, focusing on sustainable practices aimed at addressing the challenges posed by rapid urbanization and climate change. With urban areas facing increasing water stress, this study aims to identify, analyze, and evaluate a range of sustainable practices implemented across the country. The review encompasses diverse aspects of Urban Water Management, including water efficiency measures, green infrastructure initiatives, climate change resilience strategies, and pollution mitigation efforts. In examining water efficiency measures, the study investigates technological innovations and policy frameworks that have contributed to optimizing water use in urban settings. Additionally, the role of green infrastructure is explored, emphasizing its benefits and applications through case studies of successful implementations, shedding light on how nature-based solutions can enhance water sustainability. The review delves into the critical dimension of climate change resilience in urban water systems, analyzing the impacts of climate change on water resources and exploring adaptation and mitigation strategies. Infrastructure improvements and integrated planning approaches are examined as essential components in building resilient urban water systems. Addressing pollution mitigation, the study focuses on stormwater management and wastewater treatment. Best management practices and regulatory measures are scrutinized to understand how urban areas are effectively managing and treating water to mitigate pollution and protect water quality. Furthermore, the review highlights the significance of integrated water resources management as a holistic approach to addressing water challenges in urban contexts. Stakeholder engagement and cross-sectoral coordination are emphasized as integral elements in implementing sustainable and comprehensive water management strategies. Through case studies of successful urban water management projects, the review extracts valuable lessons and insights for future implementations. The challenges and opportunities in the current landscape are explored, providing a nuanced understanding of the barriers to sustainable practices and identifying emerging opportunities. This review synthesizes key findings, implications, and recommendations for advancing sustainable urban water management practices in the United States. The insights generated contribute to the ongoing dialogue on effective water management strategies in the face of evolving urban and environmental dynamics. Keywords: Urban Water Management, Sustainable Practices, Water Efficiency, Climate Change, Resilience, United States, Pollution Mitigation, Water Infrastructure.

“…The Chinese sponge city concept focuses on urban stormwater management, urban water environment, and water resource utilization to develop urban areas that respond flexibly to environmental changes to avoid natural disasters caused by rainwater [2]. Similarly, several stormwater management philosophies have been developed internationally, including the LID [3] and stormwater control measure (SCM) systems in the United States, sustainable urban drainage systems (SUDSs) in the United Kingdom [4], and the water-sensitive urban design (WSUD) approach in Australia [5]. As relevant research in these countries began in the 1970s, a comprehensive theoretical system has been established after accumulating decades of theoretical and practical evidence.…”

Owing to widespread urbanization, previously elastic and permeable ecological foundations are being continuously hardened, sealed, and channelized, leading to problems such as intensified urban convergence, water pollution, seasonal rain, and flood disasters. Urban parks and large green spaces, as rare large, cavernous bodies in cities, can effectively address the abovementioned urbanization problems. This study holistically analyzed and discussed the current developments in the sponge city concept using several case studies of recent ecologically sustainable designs for urban parks in the Yangtze River Delta region of China. Under basic conditions of the same hydrological characteristics and considering the differences in other external conditions and the environment, sponge city construction aims to address the actual characteristics and needs of specific projects, develop applicable goal-oriented sponge city constructions, and ensure design practices around a goal-oriented method. Practical problems associated with identifying specific design features, priorities, and measures were then identified according to the project location, goals, and characteristics. Thus, this study details various goal-oriented sponge city designs and their application methods to inform future design efforts.
