Lateral Seepage Flow between Low Impact Development Drainage Devices and the Underground Water Level
For Low Impact Development (LID) sites, the seepage flow simulation between the underground storage devices and the groundwater level is based on potential flow equations and Darcy's law. This paper presents solutions and a computational example for the free surface of the seepage flow and for the flow rate using the Boundary Element method and the Finite Element method, respectively. The seepage flow zone and its lateral boundary can have a major impact on the adjacent properties of an LID site. The computed hydraulic head can be a factor in the embankment slope stability if the infiltration zone is under the embankment, such as an infiltration trench installed along the gutter line of the staggered bench of embankment. In addition to the computed hydraulic head, the computed infiltration rate can be beneficial to determine whether the LID devices are effectively discharging the required amount of the infiltration flow or not.
