Vertical and Lateral Extent of the Influence of a Rain Garden on the Water Table

Where does infiltrated stormwater go? Interactions with vegetation and subsurface anthropogenic features

“…Groundwater mounding has been observed experimentally as a temporary and short-lived phenomenon (Nimmer et al, 2009;Machusick et al, 2011;Price et al, 2013) with dissipation of groundwater peaks with distance to the infiltration systems (Nemirovsky et al, 2015), though in the present case the mound was sustained over time. Substantial construction downslope of the basin should therefore consider high levels of groundwater and could require specific structural engineering.…”

Evaluation of Soil Class Proxies for Hydrologic Performance of In Situ Bioinfiltration Systems

“…The actual depth at which the GWT will begin to influence the system is dependent on the soil types and the inflow loading. A monitored site at Villanova University with sandy loam soils and an impervious area ratio of about 10∶1, for example, shows no influence from the GWT that is located approximately 3 m below the site invert (Nemirovsky et al 2014). The results of this research will be applicable to sites where the GWT depth, soil type, and design combine such that the GWT does not influence the surface infiltration.…”

“…As previously discussed, there is no accurate way to model a GWT boundary in 1D. It is not a fixed-head (zero pressure) boundary because it has been shown that mounding can occur beneath a bioinfiltration basin (e.g., Nemirovsky et al 2014), indicating that the pressure may exceed zero at the lower boundary. Because the GWT itself cannot be modeled accurately, the lower boundary condition for these simulations is a unit-gradient lower boundary condition, representing a GWT that is deep enough to not influence the simulation model (McCord 1991).…”

Impact of sewer overflow on public health: A comprehensive scientometric analysis and systematic review

“…7. It is observed that rain gardens can be used to dissipate urban storm runoffs and 50% dissipation can be achieved within two days (Nemirovsky et al, 2015). Rain gardens are green infrastructure which promote infiltration of storm runoffs into the groundwater, evapotranspiration, and capture of stormwater for reuse.…”

“…Furthermore, there is limited studies on effective utilization of rain gardens to reduce storm runoff to sewer networks during SO event. Limited studies have shown the benefits of green infrastructure, such as rain gardens in storm runoff and pollution reduction (Aad et al, 2010;Autixier et al, 2014;Nemirovsky et al, 2015;Pennino et al, 2016;Shamsi, 2012). However, their practical application in urban environments is limited.…”
