“…EGRs show significant runoff retention capacity under light and moderate rainfall events, and significant nutrient leaching occurs during rainstorm events. [23][24][25] According to the 'grade of precipitation' (CMA, 2012), single-day rainfall in Nanchang during 2010-2020 was recorded, classified and used for designing the simulated rainfall event. The simulated rainfall depth was set at 49.33 mm by averaging the single-day rainfall depths of all 197 rainfall events above heavy rainfall grade (>25 mm) in the study period.…”

“…Its permeability may decrease as incoming sediment accumulates and clogs the pores of the material; however, vegetation roots play an important role in counteracting this effect (New Jersey Department of Environmental Protection, 2004). It is recommended that its hydraulic conductivity be at least 12.5 mm/h (ARC, 2003), although other sources recommend between 50-200 mm/h (Melbourne Water, 2005) and 4-6 mm/min (Zhang et al, 2021b).…”

“…In addition, they extend the useful life of the roof and improve the thermal and acoustic insulation of the building (Reyes et al, 2016;Melo dos Santos et al, 2019). Green roofs with 10 cm deep substrates have a buffering effect on changes in temperature in the root zone (up to 13 °C lower than ambient temperature) (Reyes et al, 2016), while a substrate with 15 cm depth increases its runoff attenuation capacity (Zhang et al, 2021b). In places with semi-arid climates, they may reduce 2.2 °C (Melo dos Santos et al, 2019) and up to 5.3 °C (Reyes et al, 2016) the interior temperature of the building, compared to a regular roof.…”

“…These surfaces consist of a series of layers such as a waterproofing membrane over the deck or roof, a drainage system, anti-root layer and filtering material (if necessary) to be placed under and over the drainage, respectively, as well as a layer of substrate and plants (Reyes et al, 2016). In addition to the hydraulic conductivity and weight of the substrate, its absorption capacity (Melo dos Santos et al, 2019) and a low bulk density should also be taken into account to avoid structural damage to the roof (Zhang et al, 2021b). The thickness of the substrate can vary from a few cm to one meter.…”

In recent years, society has achieved a better quality of life; this has been possible thanks to scientific and technological advances. Among the advances that have allowed us to move forward is, without a doubt, the development of the vaccine against the SARS-CoV-2 virus. The method used for the synthesis of this vaccine was developed by Ugur Sahin and Öezlem Türeci, founders of BioNTech. Yes, behind the scientific development of greatest impact and relevance in recent years are a man and a woman. This scientific development was possible thanks to both of them, and here it is important to highlight the quality of women in science related to seeing issues from another perspective. Therefore, the union of their strengths and their differences made it possible to have a vaccine that makes it possible to return to life without confinement, without fear of going out, and with the possibility of enjoying it. Thus, the role of women in science is not only valuable, but fundamental to solve the problems that afflict us today. In this context, I can only thank and congratulate the women who today, thanks to their training, discipline and commitment, are giving us this wonderful work of science. I am sure that more challenges will come, but always counting on them, we will come out ahead. My most sincere appreciation and admiration.

“…Previous studies have identified that hydrological responses and stormwater quality are scale dependent. Structure scale mainly focuses on comparing the input and outflow runoff quantity and quality to assess individual LID performance for optimized parameter design (Hunt et al, 2008;Chen et al, 2018;Bortolini and Zanin, 2019;Zaqout and Andradóttir, 2021;Zhang et al, 2021). Catchment scale normally aims at runoff control in micro urban catchments (<0.5 km 2 ) (Hou et al, 2019;Randall et al, 2019;Yao et al, 2020).…”

Landscape patterns significantly affect urban runoff pollution, and a reasonable arrangement of pervious patches in urban catchments is critical to control urban non-point-source pollution. Low impact development (LID) can be recognized as a pervious surface type, and many previous studies have analyzed the LID performance at a system scale. However, the influence of the LID spatial distribution on runoff pollutant transport at a catchment scale remains unclear. This study analyzed the influence of pervious/impervious patterns on runoff pollution within two urban catchments constructed with LID. It was found that the runoff pollution was influenced by the area ratio, circumference, shape, and pervious patch connectivity of pervious surfaces (i.e., LID). Catchments with high perviousness ratios are more efficient in reducing the runoff volume and suspended solids, and LID should focus on removing runoff pollutants at catchments with high imperviousness ratios. Six typical landscape metrics that represented the fragmentation, complexity and vergence of pervious surfaces were selected to investigate the influence of pervious/impervious patterns on runoff pollution. The results show that larger fragmentation, smaller complexity and smaller vergence of pervious patches result in larger runoff volumes and more pollutants. Therefore, it is recommended that large pervious areas should be retained and close to one another to enhance the retention capacity of LID, and the outline of pervious patches should be long and irregular to reduce pollution confluence. The results of this study are helpful in arranging LID structures for efficient runoff regulation and pollution control at an urban catchment scale.
