“…Urbanization destroys the ecological balance of the original container structure, with river channels being constantly compressed and confined even though the water intake remains unchanged; this mismatch is a major cause of accelerated confluence and stormwater disasters [20]. Furthermore, in established urban areas with existing gray infrastructure, improving the regional gray system and using new green systems as ecological supplements for effectively managing stormwater is more practical and costeffective [17,21]. Identifying the real problems and difficulties associated with specific projects and clarifying these core issues are necessary to determine suitable goals, and thus develop applicable sponge city construction methods and nuanced solutions [9].…”

“…As noted previously, the "gray" traditional rain and flood system [17] and the "green" low-impact, ecologically integrated system (e.g., sponge city construction) [21] are the two main approaches to managing rain and floods in urban environments. In modern urban construction, both gray and green systems play critical roles in regulating urban rainwater.…”

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.

Inherited system features and challenges that can hinder urban planning initiatives must be taken into consideration before a path towards a sustainable future can be established. By putting the lock-in effect under scrutiny, it is possible to gain valuable insight to emphasize positive lock-ins and to prevent maladaptation and unsustainable solutions. This paper aims to review the current trends of urban studies regarding sustainability, resilience, and the lock-in effect, focusing on both hot topics and mutual integration by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR protocol) and analyzing the top-cited articles on these topics from 2015 to 2021 in the Web of Science database. Based on the revised literature, the potential lock-ins of climate-friendly and sustainable urban development are not adequately discussed. Moreover, while urban sustainability and resilience are often treated as overlapping areas, there is a lack of publications that carefully examine their interlinked long-term perspectives for any hindering effects.

“…Rapid global climate change has resulted in frequent occurrences of heavy rainfall around the world. With the rapid development of urbanization, the problem of urban ooding has become increasingly prominent and a key factor affecting the sustainable development of cities (Gao et al, 2022;Guo et al, 2020;; M. . Rainstorm is the essential reason for waterlogging, in recent years, scholars at home and abroad mainly focused on the in uence of rainfall return period, rainfall intensity, rainfall pattern, rainfall duration and rainfall temporal resolution when considering the in uencing factors of urban waterlogging (Hou et al, 2020;Lyu et al, 2018;Zhang et al, 2022).In addition, land use is also a dominant factor in the growing severity of urban ooding.…”

The rapid development of the city leads to the continuous updating of the ratio of land use allocation, especially during the ood season, which will exacerbate the signi cant changes in the spatial and temporal patterns of urban ooding, increasing the di culty of urban ood forecasting and early warning. In this study, the spatial and temporal evolution of ooding in a high-density urban area was analyzed based on the Mike Flood model, and the in uence mechanisms of different rainfall peak locations and in ltration rate scenarios on the spatial and temporal characteristics of urban waterlogging were explored. The results revealed that under the same return period, the larger the rainfall peak coe cient, the larger the peak value of inundation volume and inundation area. When the rainfall peak coe cient is small, the higher the return period is, and the larger the peak lag time of the inundation volume is, in which P = 50a, r = 0.2, the delay time of the inundation volume for the inundation depths H > 0.03 m and H > 0.15 m reached 32 min and 45 min, respectively, At the same time, there are also signi cant differences in the peak lag time of waterlogging inundation volume in different inundation depths. The greater the inundation depth, the longer the peak lag time of waterlogging inundation volume, and the higher the return period, the more signi cant the effect of lag time prolongation. It is worth noting that the increase in in ltration rate will lead to the advance of the peak time of inundation volume and inundation area, and the peak time of the inundation area is overall more obvious than that of inundation volume. The peak times of inundation volume and inundation area were advanced by 4 ~ 8 min and − 2 ~ 9 min for H > 0.03 m and H > 0.15 m, respectively, after the increase in in ltration rate; and the higher the return period, the smaller the rainfall peak coe cient and the longer the advance time. The spatial and temporal characteristics of waterlogging under different peak rainfall locations and in ltration capacities obtained in this study can help provide a new perspective for temporal forecasting and warning of urban waterlogging.
