“…9 Impermeable surfaces gather heat in the urban areas, which accelerates the water evaporation that could lead to more rainfalls. On the contrary, green vegetation can store rainwater, 10 and also can mitigate the urban heat island effect due to transpiration. 11,12 Specifically, plants can block solar radiation from reaching the ground and plant transpiration can cool the urban thermal environment.…”

“…For example, urban wetlands and green roofs can regulate urban runoff by capturing stormwater (McPhearson et al, 2022). The impact of UGS on urban flooding control and mitigation in urban areas has been widely investigated in previous studies from different perspectives including technical (Yang et al, 2021), planning (Afriyanie et al, 2020;Kim et al, 2021a), spatial (Baker et al, 2019), ecological (Zölch et al, 2017), social (Descher and Sinasac, 2020), economic (Sohn et al, 2021) and flood management (Ellis et al, 2021).…”

“…Urban green spaces infiltration capacity strongly depends on their biophysical and structural characteristics. Biophysical characteristics include natural attributes of plant species, health, and soil physical properties, and structural characteristics include shape, distribution, location, and connectivity (Gill et al, 2007; Kim et al, 2017; Yang et al, 2020). UGS structure has two major components: composition (the quantity and variety of UGS kinds, regardless of their spatial structure or organization) and configuration (the spatial aspect of UGS types such as arrangement, location, size, and connectivity) (Farina, 2000).…”

Flooding is increasing in urban areas around the world, leading to loss of life and property damage, and cities are using urban green spaces (UGS) for flood regulation. The spatial attributes of UGS have an important role in controlling and regulating urban flooding, and there is a need for a systematic map on how spatial factors of UGS, such as shape, size, location, or connectivity, impact flooding in urban areas. The objectives of this study are to analyze and synthesize published material to evaluate the impacts of the spatial dimensions of UGS on flood regulation and to identify knowledge gaps and future research directions. Pertinent literature was reviewed and synthesized using the systematic mapping method. The results of this study show that previous research on spatial configuration have examined how variables such as slope, DEM, green space coverage, and landscape shape index impact runoff reduction. Slope was found to be an important, but not determining factor in flood regulation. There is a need for further research on how the geographic context of urban regions, including climatic conditions and land use changes, impacts UGS functionality. Additionally, there is a need for further research on how the spatial configuration of UGS impacts flood vulnerability and intensity, two under-addressed yet important topics in urban flooding.

“…Lastly, blue infrastructure (e.g., rainwater harvesting/rain barrels, spring water collection, floodplains, underground detention/infiltration) and green infrastructure (e.g., swales, rain gardens/bioretention cells, Sustainability 2022, 14, 7109 2 of 18 green streets) are alternative approaches to addressing the problem with limited impacts on nature-LIDs [5] (i.e., reducing water pollution, irrigating parks) [6]. Both green and blue infrastructure projects utilizing sustainable approaches have been successfully applied due to the trade-off among the multiple benefits of green-blue land uses in Brazil [7], China [8], EEUU [9], and the U.K. [10]. However, their applicability is still a challenge for developing countries due to scarce resources and the absence of a holistic approach [11].…”

Influence of Low-Impact Development in Flood Control: A Case Study of the Febres Cordero Stormwater System of Guayaquil (Ecuador)

Urban flooding is a major problem in many coastal cities. The rapidly shifting patterns of land use and demographic increase are making conventional approaches to stormwater management fail. In developing countries such as Ecuador, a lack of monitoring, financial constraints and absence of proper policies exacerbate flooding problems. This work assesses the implementation of two Low Impact Development strategies (LIDs), namely, green streets and rain barrels, as nature-based solutions to mitigate flooding problems. The use of the “Stormwater Management Model” (SWMM) helped to contrast the new approach with the current state of the drainage system, including normal and extreme scenarios. With an implementation of 1.4% (19.5 ha) of the total area with LIDs, the reduction of runoff for short events (200 min) is around 20%, and for extreme events (within 24 h) is around 19% in comparison to the conventional approach. Flooded nodes were reduced to 27% for short events, and to 4% for extreme events. The peak flooding system had a reduction to 22% for short events and 15% for extreme events. These highlights help to increase city resilience, and authorities and stakeholders should engage in climate actions to reduce flood risks complementing drainage operations with nature-based solutions. Moreover, calibrated results in this article serve to increase awareness among municipal authorities regarding the importance of maintaining flooding records to improve modelling results for decision-makings processes.
