Groundwater

With our long-term experience in the set-up, calibration and application of numerical flow and transport models in porous media, we are happy to assist you with the planning and cost-effective implementation of your projects with groundwater impact.

  • Set-up of 2D and 3D groundwater-models (small and regional scale) for quantification of flow regimes (SPRING/ FEFLOW)
  • Set-up of 1D and 2D hydraulic models for the description of groundwater and surface-water interactions (quantification of in- and exfiltration processes)
  • Steady-state and transient, inverse automatic fitting of hydrogeological parameters (conductivity, storage coefficient, leakage factor)
  • Numerical simulation of pump and tracer tests (model calibration and validation)
  • Maintenance and updates of calibrated groundwater models (mesh refinement, recalibrations with respect to latest data, implementation of new structures)
  • Data acquisition and cleansing as well as statistical evaluation of model uncertainties
  • Web-based presentation of simulation results

  • Calculation of catchment areas and protection zones of private and public groundwater wells (drinking water abstraction, heat pumps, etc.)
  • Process and pumping rate optimizations (e.g. cost reductions for groundwater infiltrations, dimensioning of construction dewatering)
  • Realtime models including realtime monitoring systems
  • Transport modeling (inverse transport simulations for the calculation of protection zones, hydrogeological quantification of polluted areas and remediation measures)
  • Numerical support for license applications (determination of maximum pumping rates, validation of long-term pressure drops and temperature differences)

  • Validation of the effects of complex structures on the existing flow field (tunnels, portals, docks, flood control structures, etc.) for the construction level and final state
  • Optimization of construction dewatering (production rate, drawdown)
  • Validation of compensation measures for the recovery of the original flow regime (sewer pipes, ditches, wells, etc.)
  • Evaluation of thermal and hydrogeological gravel mining effects on the groundwater aquifer
  • Evaluation of the effects of hydroelectric power stations on the groundwater aquifer
  • Validation of river restoration measures (river widening, meandering, etc.)
  • Optimization and validation of flood protection measures (e.g. flood detention basins, river bed corrections)

  • Simulation of temperature distributions in the groundwater aquifer
  • Simulation of thermal groundwater usage (heat pumps and cooling systems, thermowells, etc.)
  • Simulation of deep geothermal energy systems
  • Derivation of heat potential maps
  • Validation of thermal variances based on constructions with groundwater impact
