“…To date, various types of single NBS sites have been studied with objectives such as reduction of the flood peak (Carpenter and Kaluvakolanu, 2011;Ercolani et al, 2018;Liao et al, 2015;Mei et al, 2018;Yang et al, 2018), delay/attenuation of the flood peak (Ishimatsu et al, 2017), reduction of volume of combined sewer overflows (Burszta-Adamiak and Mrowiec, 2013) and reduction of the surface runoff volume (Lee et al, 2013;.…”

“…The most common NBS measures in urban areas appear to be intensive green roofs (Burszta-Adamiak and Mrowiec, Carpenter and Kaluvakolanu, 2011;Ercolani et al, 2018), extensive green roofs (Cipolla et al, 2016;Lee et al, 2013), rain gardens (Ishimatsu et al, 2017), rainwater harvesting (Khastagir and Jayasuriya, 2010), dry detention ponds (Liew et al, 2012), permeable pavements , bio-retention (Khan et al, 2013;Olszewski and Allen, 2013), vegetated swales (Woznicki et al, 2018) and trees (Mills et al, 2016). However, the authors of these studies investigated the performance of such measures individually (i.e.…”

“…The literature to date acknowledges that the effectiveness of NBS greatly depends on the magnitude and frequency of rainfall events. Green roofs are recognized in reducing peak flows more effectively for smaller magnitude frequent storms than for larger magnitude infrequent storms (see for example, Ercolani et al, 2018). There are also reports that rain gardens are more effective in dealing with small discharges of rainwater (Ishimatsu et al, 2017).…”

Abstract. Natural hazards such as severe floods, storm surges, landslides, avalanches, hail, windstorms, droughts, heat waves and forest fires occur almost daily. This situation is likely to become worse given the projected changes in climate, degradation of ecosystems, population growth and urbanisation. The new concepts such as Ecosystem-based Adaptation, Green Infrastructure and/or Nature-Based Solutions have emerged as effective means to respond to such challenges. The present paper provides a critical review of the literature and identifies current knowledge gaps and future research prospects. There has been an explosion of scientific publications on this topic with a more significant rise taking place from 2007 onwards. Hence, the review process started by sourcing 1381 articles from Scopus which were also cross-referenced with the articles sourced from Web of Science and Google Scholar. The full analysis was performed on 159 closely related articles. The analysis confirmed that numerous advancements have been achieved to date. These solutions have already proven to be valuable in providing sustainable, cost-effective, multi-purpose and flexible means for hydro-meteorological risk reduction. However, there are still many areas where further research and demonstration is needed in order to promote their upscaling and replication and to make them become mainstream solutions.

“…Analyzing LID through coupling modeling software with a multi-objective optimization using genetic algorithms has been a common method [22,27]. Ercolani et al used the MOBIDIC-U hydrologic model equipped with SMART-GREEN, which is a Quantum Geographic Information System (QGIS) plugin interface, to study the effects of green roofs in an urban watershed [28]. Their study revealed that green roofs might work better under more frequent storms of smaller magnitude, and their efficiency can be increased with spatially heterogeneous implementation.…”

To address regional flooding in the United States, federal and state agencies are adopting strict drainage policies in any large-scale commercial development within the watershed boundary. The conventional approach of implementing a wet detention pond (WP) reduces the land cover and causes operation and maintenance challenges eventually. The present study developed a decision-support system (DSS) in the Lower Rio Grande Valley region of South Texas for optimal selection of Best Management Practices (BMPs) by substituting a portion of the WP footprint with three regionally promising low-impact development practices, namely, porous concrete pavement (PCP), bioretention (BR), and bioswale (BS). Source Load Assessment and Management Model for Windows (WinSLAMM) was used as the foundation for the DSS database and algorithm development. This tool suggested that the implementation of bioswale alone can considerably reduce the footprint and construction cost. Less than 0.95 ha of installation of BR and BS can mitigate 79–91% of runoff from a maximum of 5 ha of commercial development. A combination of BR, BS, and WP was found to reduce runoff significantly (~100%), which suggests that the successful adoption of DSS might support better planning of the urban stormwater management in the Lower Rio Grande Valley (LRGV).

A Novel Buffer Tank to Attenuate the Peak Flow of Runoff

Impermeable pavements and roofs in urban areas convert most rainfall to runoff, which is commonly discharged to local sewers pipes and finally to the nearby streams and rivers. In case of heavy rain, the peak flow of runoff usually exceeds the carrying capacity of the local sewer pipes, leading to urban flooding. Traditional facilities, such as green roofs, permeable pavements, soakaways, rainwater tanks, rain barrels, and others reduce the runoff volume in case of a small rain but fail in case of a heavy rain. Here we propose a novel rainwater buffer tank to detain runoff from the nearby sealed surfaces in case of heavy rain and then to discharge rainwater from an orifice at the tank’s bottom. We found that considering a 100m2 rooftop with 0.80 runoff coefficient and a 10cm rainfall depth for an hour, a cubic tank with internal edge side of a square of 2 m attenuates the peak flow about 45%. To reduce a desirable peak flow, the outlet orifice of the buffer tank must be optimized according to site-specific conditions. The orifice can be set at an elevation from the tank’s bottom to create a dead storage for harvesting rainwater.
