Services on basis of multi-disciplined work:

Specific offers:

geological site analysis and evaluation, elaboration of three-dimensional model
evaluation of pumping tests by use of UP, HYDROTEC and PVBC software solutions
implementation of a GIS database (independent of the model)
determination of parameters, model design and calibration of saturated and partly saturated models
re-calculation of historic development
investigations on hydrological budgets
determination of the recharge area borders
implementation and parameterisation of mass transport models, performance of mass transport simulation

Utilised software solutions:

finite-elements: FEFLOW and SPRING
finite-differences: VISUAL MODFLOW, PROCESSING MODFLOW, ASM
available experience with PCGEOFIM
calculation of groundwater recharge and water budgets (for cover systems, waste rock dumps etc.) with HELP, BOWAM und HYDRUS2D

Modelling of mine flooding:

development of site-specific approach
determination of regional model providing hydraulic and geochemical boundary conditions for flooding
determination of a compartment model for the mine by use of GoldSim© software and analysis of different processes in the mine
water and mass balances of complete river recharge areas
additional consideration of mobilised pollutants released from waste rock dumps, heaps, open-cast mines, underground mines, tailings ponds and contaminated sites
modelling of pollution spreading in surface water bodies and aquifers
