Development of a new mathematical model for subsurface water quality management

摘要

The interfaces between free (e.g., groundwater) and porous (e.g., soil) flow zones in the subsurface represent important transition zones across which many important transfer/exchange processes occur. The understanding of these interactive phenomena and the way these regions behave in combination is, therefore, critical for management of subsurface water quality. Indispensable to-this is numerical modelling and simulation as they can handle complex flow domains and minimise the analysis cost and time. In the present work, the hydrodynamic conditions for a combined free and porous flow domain in the. subsurface are analysed. An investigation into the fluid dynamical behaviour for different aspect ratios of the domains is of most interest. [References: 18]
