“…Zhou et al (2022) analyzed the distribution of extreme precipitation in China, and found that extreme precipitation in China showed obvious differences due to different geographical locations [18]. Zhang et al (2018) studied the impact of surface runoff on urban water storage capacity [19]. The frequency of urban water disasters caused by rainstorm or continuous rainfall can be reduced by improving the capacity of urban drainage facilities [20][21].…”

As an innovative means to promote low-carbon and ecological development of cities, sponge cities have attracted extensive attention from industry and scholars. Measuring the operation efficiency of a sponge city can effectively measure whether the current input and output are reasonable, whether the management and operation are scientific, etc., which can find out the weaknesses in the current process and management. This paper proposes an evaluation method of interval cross-efficiency combined with TOPSIS and DEA to measure the operating efficiency of a sponge city. Specifically, an evaluation system, that includes three inputs and six outputs, is established at first from the perspective of input and output. Secondly, due to the uncertainty of the natural environment, two DEA models of benevolent and aggressive models are adopted to obtain the cross-efficiency interval value of a sponge city. Next, the cross-efficiency interval values are aggregated based on TOPSIS, and then, the descending principle is introduced to rank sponge cities to obtain the optimal operation efficiency cities. Finally, a case is used to verify the effectiveness of the proposed method. The research idea of this paper is clear, the research method is simple, and the research results can provide a basis for building an efficient and high-level sponge city.

“…Urban green patterns have also been analyzed in stormwater management studies. Researches provide interesting results on the impact of patterns of pervious and impervious surfaces on stormwater runoff [66] and some studies analyze the influence of urban green patterns [67][68][69], but this research path is still little addressed and further analysis is needed. Although urban green patterns seem to represent a key point to enhance urban resilience, further studies are needed to better understand their impact on ecosystem services.…”

Reading Urban Green Morphology to Enhance Urban Resilience: A Case Study of Six Southern European Cities

A loss of natural capital within cities and their surrounding areas has been noticed over the last decades. Increasing development associated with higher sealing rates has caused a general loss of Urban Green Spaces (UGS) within the urban environment, whereas urban sprawl and the improvement of road networks have deeply fragmented the surrounding landscape and jeopardized ecosystems connectivity. UGS are an essential component of the urban system, and their loss has a greater impact on, e.g., ecological and hydrological processes, threatening human well-being. Different types and spatial configurations of UGS may affect their own ability to provide ecosystem services, such as biodiversity support and water regulation. Nevertheless, the study of UGS spatial patterns is a research branch poorly addressed. Moreover, UGS analyses are mainly focused on public and vast green spaces, but seldom on informal, private, and interstitial ones, returning a myopic representation of urban green areas. Therefore, this study investigates the UGS spatial patterns within six Southern European cities, using the urban morphology analysis to assess all urban vegetated lands. Results revealed three main Urban Green Spatial Patterns (UGSPs): Fragmented, Compact, and Linear Distributions. UGSPs taxonomy represents a novelty in the urban morphology field and may have important implications for the ability to provide ecosystem services and, thus, human well-being.

“…In recent years, climate change has greatly affected the hydrological cycle and patterns of precipitation and has led to increasing amounts of surface runoffs and urban floods [4,5]. On the other hand, rapid urbanization contributes to increasing impervious surfaces and has impacts on both flood hazards and vulnerability due to changes in the population, wealth and infrastructure [6,7]. Flood risks in many regions are rising and result in great damages [8,9].…”

Urban floods are detrimental to societies, and flood mapping techniques provide essential support for decision-making on the better management of flood risks. This study presents a GIS-based flood characterization methodology for the rapid and efficient identification of urban flood-prone areas, which is especially relevant for large-scale flood hazards and emergency assessments for data-scarce studies. The results suggested that optimal flood mapping was achieved by adopting the median values of the thresholds for local depression extraction, the topographic wetness index (TWI) and aggregation analyses. This study showed the constraints of the depression extraction and TWI methods and proposed a methodology to improve the performance. A new performance indicator was further introduced to improve the evaluation ability of hazard mapping. It was shown that the developed methodology has a much lower demand on the data and computation efforts in comparison to the traditional two-dimensional models and, meanwhile, provides relatively accurate and robust assessments of flood hazards.
