“…From the figure, we can see that the peak flow difference is larger for the 3-month design storm (at 46.7%) as compared to the 10-year design storm (at 32.6%), suggesting that the ABC Waters design features implemented are more effective in reducing peak flow for smaller storm events as compared to larger ones. Similar observations were also reported in other bioretention studies [16][17][18]22]. This is generally expected for typical rain gardens (since smaller storm events would result in less surface overflow as compared to larger storm events) and is hence a somewhat surprising observation considering the design of the rain gardens and gravel swales in the precinct which are coupled with underground gravel storage and orifice outlets.…”

“…There are modelling as well as field monitoring studies on the effectiveness of SuDS/LID/WSUD/GI in reducing peak flow within temperate catchments internationally [9][10][11][12][13][14][15][16][17][18]. However, the studies on SuDS application in tropical climates are limited.…”

“…Taking the example of bioretention systems (i.e., vegetated land depressions that are designed to detain and treat storm water runoff via sedimentation, filtration and biological uptake [4], which is a type of ABC Waters design feature), they have been reported to be able to achieve runoff peak flow reduction in the range of 24-99% in the United States of America (USA) [15,17,[19][20][21] and 80-90% in Australia [22,23] based on field monitoring studies. The peak flow reductions depend on the ratio of catchment area to bioretention area, the drainage configuration and the rainfall magnitude, with smaller peak flow reductions being achieved for higher rainfall intensities as well as increased rainfall depths and longer rainfall durations [16][17][18]21]. Hence there is a need for region specific study due to the large variations in the peak flow reduction effectiveness of the bioretention systems [20].…”

Active, Beautiful, Clean Waters (ABC Waters) design features-natural systems consisting of plants and soil that detain and treat rainwater runoff-comprise a major part of Sustainable urban Drainage Systems (SuDS) in Singapore. Although it is generally accepted that ABC Waters design features are able to detain runoff and reduce peak flow, their effectiveness in doing so has not been studied or documented locally. This research aims to determine their effectiveness in reducing peak flow based on a newly constructed pilot precinct named Waterway Ridges. Four types of ABC Waters features have been integrated holistically within the development, and designed innovatively to allow the precinct to achieve an effective C-value of 0.55 for the 10-year design storm; the precinct-wide integration and implemented design with the aim of substantially reducing peak flow are firsts in Singapore. The study is based on results from an uncalibrated 1D hydraulic model developed using the Storm Water Management Model (SWMM). Identification of key design elements and performance enhancement of the features via optimisation were also studied. Results show that the features are effective in reducing peak flow for the 10-year design storm, by 33%, and allowed the precinct to achieve an effective C-value of 0.60.

“…Several studies have investigated the subsurface hydrological processes of bioretention cells in field or laboratory experiments (Li, Sharkey, Hunt, & Davis, 2009;Brown & Hunt, 2011a;Brown & Hunt, 2011b;Winston, Dorsey, & Hunt, 2016), but they have mostly just reported the exfiltration and groundwater recharge as one component of the water budget. Machusick, Welker, and Traver (2011) investigated the groundwater mound beneath a bioretention cell by field monitoring and observed a strong correlation between the precipitation depth and the groundwater mounding, and the groundwater mound was mainly localized at the bioretention cell.…”

Evaluating hydrologic performance of bioretention cells in shallow groundwater

Bioretention cells, which are generally effective in controlling surface runoff and recharging groundwater, have been widely adopted as low impact development practices. However, shallow groundwater has limited their implementation in some locations due to the potential problems of a reduction in surface runoff control, groundwater pollution, and continuous groundwater drainage through the underdrain. Many guidelines have established minimum requirements for the groundwater depth below bioretention cells, but they may not be optimized for certain environmental conditions and bioretention cell designs. This study made use of a variably saturated flow model to examine the hydrologic performance of a single bioretention cell in shallow groundwater with event‐based simulations, considering a wide range of initial groundwater depths, media and in situ soil types, surface runoff loads, and underdrain sizes. Performance indicators (e.g., runoff reduction, time for infiltrated water to reach the bioretention cell bottom and the groundwater table, and height and dissipation time of groundwater mound) were evaluated to examine the processes of runoff generation, the formation and dissipation of groundwater mounds, and the bioretention cell's performance in a shallow groundwater environment. The most influential factors were the initial groundwater depth, the hydraulic conductivity of the media soil, and the rainfall runoff load. With a deeper initial groundwater table, infiltrated water took longer to reach the bioretention cell bottom and groundwater table. Groundwater mounds, however, took longer to dissipate even though they were smaller. The groundwater quality can be better protected if relatively less‐permeable soil types (e.g., sandy loam) are used as the media, although it may compromise the performance in runoff quantity control. However, only very high surface runoff loads would cause concerns regarding a reduction in runoff quantity control and possible groundwater contamination due to the shallow groundwater. A distance of 1.5–3 m between the bioretention cell bottom and the groundwater table is generally sufficient. The results of this study could help to guide the planning and design of bioretention cells in areas of shallow groundwater.

“…High volumes of SWR can overwhelm infrastructure and cause flooding damage, which incurs additional economic costs (Ahiablame, et al 2012). High volumes of SWR have also been shown to cause stream bank erosion and concurrent ecosystem damage; in one study in Pennsylvania, the urban streams were found to erode to a width 3.8 times larger than rural streams (Winston, et al, 2016).…”

AcknowledgementsThis work would not have been possible without the funding and research facilities of the Virginia Department of Transportation (VDOT) and its research branch, the Virginia Transportation Research Council (VTRC). The opportunities for implementation provided by VDOT are greatly appreciated.I would like to thank the following individuals for their contributions to the success of this research:  Dr. Celik Ozyildirim (thesis co-advisor), whose indomitable enthusiasm for concrete technology guided this project to speedy success.  Dr. Teresa Culver (thesis co-advisor), for her invaluable input with regards to stormwater management. iii AbstractStormwater runoff is a major concern as more land is developed into urban settings, morphing areas previously capable of infiltrating a large amount of water into impervious surfaces on which contaminants are collected and large volumes of runoff flow. Many effective practices for managing stormwater runoff exist currently with each method dependent on the surrounding development and the demands of that specific application. One treatment method available now is pervious concrete (PC), a type of permeable pavement that allows runoff to infiltrate, thus capturing contaminants before they reach the groundwater and slowing the runoff to alleviate flooding. Virginia Department of Transportation (VDOT) currently has no applications of pervious concrete. The purpose of this study was to conduct a literature review, field observations, and laboratory work to formulate a special provision by which VDOT could implement the technology of pervious concrete as a stormwater management tool. The results of the literature review, field observations, and laboratory work are presented in addition to the special provision formulated specifically for VDOT. From the work conducted in this study, it is evident that PC is a candidate for stormwater management that could perform satisfactorily in the Virginia climate and could be constructed with locally available materials.
