GROUNDWATER MODELING
FIELDS OF APPLICATION
- Hydrogeology, tunneling and drinking water protection- Engineering geology and geotechnics- Geothermal energy (borehole heat exchanger, ground-
water heat pump installation, reservoir modeling)- Environment and contaminated sites- Natural hazards and risks- Resources and mining
WORKFLOW
- Data collection, compilation and assessment- 3D geological modeling- Groundwater conceptual model- Numerical modeling - Model calibration and uncertainty analysis, incl. PEST
and Pilot Points- Export / Import with standard industry software (CAD,
GIS, Web-GIS,…)
GROUNDWATER MANAGEMENT
- Prediction of groundwater levels and water availability- Design of groundwater management and planning scheme- Delineation of groundwater protection areas- Surface water/groundwater interaction- Definition of short-term and long-term scenarios- Uncertainty analysis
NATUR AL HA ZARD
- Simulation of groundwater levels- Delineation of flooding areas- Risk assessment
ENVIRONMENT AND CONTAMINATED SITES
- Simulation of short-term to long-term behavior- Planning and assessment of remediation installations- Delineation of contaminant plume in groundwater- Impact of further construction activities
GEOTHERMAL APPLICATIONS
- Design of groundwater heat pump installations- Design of borehole heat exchangers- Assessment of potential conflict with other users- Simulation of deep geothermal reservoirs- Support for authorization process
CONSTRUCTION SITE / GEOTECHNICAL FIELD
- Design of dewatering, infiltration and drainage scheme- Quantification of groundwater inflow into excavation
pits or tunnels- Measures for minimizing the environmental impact
APPLIED SOF T WARE
- FEFLOW, MODFLOW: groundwater and thermal modeling- PEST: Parameter Estimator, incl. Pilot Points method- MOVE, LEAPFROG: 3D geological modeling- PLAXIS: geotechnical modeling
