ABSTRACT: To mitigate
the adverse impact of urbanization around the world, several best management practices,
in other words green infrastructures, have been used in a way that protect the natural
hydrology of the catchment and are more beneficial to the environment. Soak-away
rain garden, shallow, landscaped depressions commonly located in parking lots or
within small pockets in residential areas, is one of those best management practices
or green infrastructures. However, though in the past few decades the mathematical
modeling work and the science of computer simulation have enhanced the understanding
of hydrological processes, there is still a lack of modeling studies that focus
on understanding the three-dimensional (3D) hydrological processes, such as the
3D ex-filtration process of a soak-away rain garden in a sufficient level of details.
Thus, this paper develops a 3D mathematical model to represent the hydrological
processes of a soak-away rain garden using COMSOL Multiphysics Java API, a Java-based
interface of COMSOL Multiphysics. The developed model is demonstrated with a design
hyetograph of 3-month average rainfall intensities of Singapore.
