With urbanization, the permeable soil surface area through which recharge by infiltration can occur is reducing. This is resulting in much less ground-water recharge and greatly increased surface run-off. Infiltration devices, which redirect run-off waters from the surface to the sub-surface environments, are commonly adopted to mitigate the negative hydrologic effects associated with urbanization. An infiltration trench alone or in combination with other storm water management practice is a key element in present day sustainable urban drainage systems. A solution for the infiltration rate from an infiltration trench and, consequently, the time required to empty the trench is presented. The solution is in the form of integrals of complicated functions and requires numerical computation. The solution is useful in quantifying infiltration rate and/or artificial recharge of ground-water through infiltration trenches and the drain time of the trench, which is a key parameter in operation of storm water management practice. The solution has been applied to a case study area in Lyon, France. MATLAB programming has been used in the solution Read More: http://ascelibrary.org/doi/abs/10.1061/%28ASCE%29IR.1943-4774.0000408
