Explanation of how the FEP is treated
Excavation/operation: Modelling of inflow, water table drawdown and salt water upconing assuming saturated groundwater flow using DarcyTools. MIKE SHE used for simulating water table drawdown effects in detail.
Temperate: Modelling of backfill resaturation using DarcyTools and saturated groundwater flow on different scales using ConnectFlow.
Periglacial: Modelling of saturated groundwater flow on a super-regional scale using DarcyTools.
Glacial: Modelling of groundwater flow on a super-regional scale during advance and retreat of ice sheets, with and without permafrost, using DarcyTools.
Earthquakes: Impact on groundwater flow not specifically addressed but simplified calculations of radionuclide transport carried out (see Ge24).
