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.展开更多
