Groundwater Modelling (FEFLOW, DHI-WASY)

To analyse and quantify flow and transport processes in groundwater, the finite element model system FEFLOW from DHI-WASY is preferred. According to the problem, adequately compiled steady state or transient groundwater flow models form a consistent basis for the evaluation of flow paths and flow time. The flow model is the basis for further questions as well concerning mass or heat transport. It allows for the delineation of catchments, the assessment of risk potentials or the estimation of consequences of  interference by mankind, for example. In complex applications, coupling with groundwater recharge models, hydraulic models for surface water or water balance models can be used for further refinement.
Our groundwater models allow - where appropriate with the use of additional field data - the answers to questions like:

• flow time and contributing areas
• definition of protective areas
• groundwater - surface water interaction
• water composition and water age
• mass transport: vulnerability assessment and catchment delineation using reverse mass transport approaches
• near-surface geothermal energy: influence of thermal groundwater utilisation, thermal fields
• interpretation and optimisation of groundwater monitoring data
• optimisation of groundwater exploitation
• threats due to problem sites and hazardous inputs
• influence of infiltration plants or filling of flood protection reservoir in depth to groundwater
