Urban tunnelling projects can result in local water table declines and groundwater gradient changes. These impacts have the potential to destabilize building foundations and mobilize contaminated groundwater. This project involved construction of a regional scale FEFLOW model to simulate the impact upon groundwater flow of a major road tunnel below the city of Melbourne, Australia. […]
Managing water inflow into mine pits is a challenging aspect of mine development. This work involved testing numerous, alternative, water-management strategies designed to reduce groundwater inflow and included, freezing a portion of the aquifer to reduce groundwater inflows during mining. Each alternative strategy was quantitatively assessed based on realizations from previously conducted nonlinear, parameter uncertainty […]
