Figure 4 shows computed steady state groundwater heads affected by pumping according to planned mine dewatering. The hydrogeological impact produced by mine dewatering would be very limited to the near surroundings but in the north, where a higher propagation of the groundwater drawdown is predicted due to the influence of 2 major water-conducting fracture zones (Figure 4).

Environmental Software

Real-time groundwater level data imaging will be used by drinking-water purveyors and industrial users to better manage groundwater aquifers as a resource both for storage and withdrawal. By turning remotely-sensed data into 2- and 3- dimensional graphics in real time using sophisticated mathematical tools, the black box of subsurface conditions become better understood and therefore manageable.
