Assessment of porous pavement effectiveness on runoff reduction under climate change scenarios

Abstract

A B S T R A C TClimate change has affected both water quantity and quality by increased rainfall, runoff, and associated pollutant loading in urban areas. Stormwater Best Management Practices (BMPs) are now being popularly considered for the reduction of increased runoff due to urbanization. Most research has been conducted on the analysis of BMP effectiveness under current conditions. However, there is no extensive literature on BMP effectiveness studies considering climate change. In this study, the effectiveness of BMP, porous pavement in particular, has been assessed under climate change scenarios. Climate change scenarios were generated by trend analysis of the historical rainfall data. The 2-year and 100-year design storms having 24-h durations were determined for three scenarios: current conditions, 2020, and 2050 using frequency analysis. Storm Water Management Model was then calibrated and used to evaluate the impact of climate change and the effect of incorporating porous pavement on runoff. Geographic information system analysis showed that 33.4% of the basin was suitable for the installation of porous pavement. Hydrologic modeling demonstrated that climate change can increase peak flows by as much as 26.9% relative to current condition. Further analysis showed that porous pavement can be effective in reducing the runoff volume and peak flow below current conditions for all scenarios, offsetting negative impact of climate change.

Hydrologic Performance of Permeable Pavement as an Adaptive Measure in Urban Areas: Case Studies near Montreal, Canada

“…These authors found that the concentration of suspended solids and heavy metals are reduced by at least 50% when stormwater filters through permeable pavement. With regard to hydraulic performance, Abbott and Comino-Mateos (2003), Collins et al (2008), Fassman and Blackbourn (2010), Pratt et al (1989;1995), TRCA (2008), Huang et al (2012), Drake et al (2012;2014a) and Kim et al (2015) all showed, for various individual cases, that permeable pavement helps reduce peak flow rate and runoff volume in the storm sewer system during rainfall events. Among these authors, only Drake et al (2014a), Drake et al (2012), Huang et al (2012) and TRCA (2008) demonstrated these effects in a harsh winter climate, with winter thaws, such as those occurring in southern parts of Canada.…”

Hydrological impact assessment on permeable road pavement with subsurface precast micro‐detention pond

“…In the pervious area, there was no runoff at all for the first 7 to 12 minutes of the storm, as the depression storage and available infiltration capacity were sufficient to capture all rainfall volume during this period. The expected findings are supported by Kim et al (2015) and Barszcz (2015), where peak flow and total runoff volume after permeable pavement controlled are smaller than the values of the existing condition with AP, indicating that pervious pavement has infiltrated most of the runoff into groundwater. Overall, the runoff hydrograph for 15 min 100-yr storm was the largest.…”

“…Permeable pavements have been widely used since 1982 in the USA and in the 1990s in Canada, Europe and Japan as a measure to control stormwater (Mosquera and Drake, 1998; Pratt, 1999; Dietz, 2007; O’Sullivan et al ., 2011). Permeable pavements have been extremely effective in infiltrating stormwater runoff (Watanabe, 1995; Fach and Geiger, 2005; Zhou and Li, 2008; Bastien et al ., 2011; Sañudo‐Fontaneda et al , 2013; Barszcz, 2015), significantly reducing runoff volume (Pratt et al ., 1989; Davey and Maziliauskas, 2003; Lin et al ., 2014; Timm et al ., 2018) and minimising peak flow (Price, 1994; Kim et al ., 2015; Imteaz et al ., 2018; Su et al ., 2019). Permeable pavements that commonly used are pervious concrete (PC), porous asphalt (PA) and permeable pavers.…”

“…Permeable pavements that commonly used are pervious concrete (PC), porous asphalt (PA) and permeable pavers. PC and PA are permeable variations of concrete or asphalt, where the binding agent coats the aggregate particles without filling the voids between the particles (Kim et al ., 2015). Permeable pavers are also commonly known as permeable interlocking concrete pavers (PICP), which are composed of modular units separated by joints filled with open‐graded aggregate (ICPI, 2013).…”

Applicability of SWMM for semi Urban Catchment Flood modeling using extreme Rainfall Events

“…For Hydrologic designs computation of rainfall extremes is important for both structural as well as non-structural flood protection measures [9]. SWMM is the open source software tool which is available most widely for research activities and solving real problems of Urban Floods in an urbanized catchment [10]. From this we can easily incorporate modeling capabilities for both hydraulic and hydrologic conditions which is its major advantage over other Applicability of SWMM for semi Urban Catchment Flood modeling using extreme Rainfall Events available tools.…”
