FEFLOW is suitable for numerous different applications in flow and transport processes simulation in porous media, ranging from lab scale to continental scale. A few typical examples are listed here:

• Study of pollutant dispersion
• Evaluate remediation and decontamination strategies
• Study of groundwater drawdown and rise in mining areas
• Mine dewatering studies
• Survey of saltwater intrusion
• Isotope calculation for detection of groundwater age
• Design of geothermal power plants (HDR, heat pump systems)
• Coupled groundwater/surface water simulation via online linking with Mike11 (by DHI) and Hydro_AS-2D (by M. Nujic)

• Geotechnical applications (tunnel construction, construction site dewatering)
• Calculation of dam seepage
• Soil-column calculations
• Infiltration calculation
• Assessment of availability of groundwater resources
• Estimation and control of strategies for groundwater management
• Design of well-head protection zones
• Studies for environmental impact assessments
• Design of groundwater monitoring programs
• Applications in research

For extending the built-in capabilities of FEFLOW, its open programming interface IFM offers nearly unlimited possibilities.
