Environmental Protection

GeoStudio provides comprehensive tools for analyzing mining and environmental protection.

The analytical challenge


Production and disposal of mining and municipal waste poses many challenges from a geotechnical design and analysis perspective. Proper initial design can lead to much more efficient management of waste during and after project closure. Issues of concern from an analysis perspective include: stability of waste deposits such as landfills, waste rock and tailings impoundments; seepage of water, gas and contaminants through these facilities; design of cover or cap systems to prevent water infiltration or the release of gases and water; settlement and consolidation of waste; long term performance; and heterogeneity of waste and the associated characterization of material properties.

The GeoStudio solution


GeoStudio can address issues from pre-construction and construction stages, as well as long term performance analysis. The strength of the integration capability in the software allows for differing levels of complexity. Both steady state and transient process can be considered, as can the coupling of heat, gas and water fluxes to climate conditions. In addition, seepage models can be linked with contaminant transport models or with slope stability models as required for a comprehensive solution.

Advection-Dispersion with Adsorption and Decay

Contaminant transport due to advection and dispersion can be easily modeled with GeoStudio's multi-physics functionality. Mass transport analyses may also include the effects adsorption and decay, and can be used to investigate mass discharge to points of concern, like freshwater streams.

Water Transfer through Soil Covers

Climatic effects on mass and heat transfers within a soil cover can be modeled using the Land-Climate Interaction and Surface Energy Balance boundary conditions. Model inputs include climate and vegetation data, and the simulation results provide insight on deep percolation, evaporation, and root-water update.

Transport and Consumption of Oxygen 

Soil cover systems with capillary barrier effects are often built to limit oxygen ingress towards mine wastes containing sulphide. GeoStudio can be used to analyze oxygen transport through an unsaturated cover system and explore the effectiveness of oxidation within the water retention unit.
