  2. 1. Groundwater Recharge in Crystalline Bedrock : Processes, Estimation, and Modelling

    Author : Niclas Bockgård; Sven Halldin; Allan Rodhe; Auli Niemi; Lars O. Ericsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; groundwater recharge; bedrock; crystalline rocks; tracers; CFC; surface loading; loading efficiency; barometric effect; heterogeneity; stochastic modelling; Hydrologi; Hydrology; Hydrologi;

    Abstract : Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. READ MORE

    Author : Olga M. Maskenskaya; Mats Åström; Kjell Billström; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; secondary minerals; rare earth elements; isotopes; crystalline bedrock;

    Abstract : This thesis focuses on the geochemistry of secondary minerals, mainly calcite but also others such as fluorite and Ca/Al silicates, precipitated throughout the last 1.5 billion years in fractures of crystalline rock, SE Sweden. READ MORE

  5. 3. Fluoride in surface water and groundwater in southeast Sweden : sources, controls and risk aspects

    Author : Tobias Berger; Mats E. Åström; Pasi Peltola; Henrik Drake; Olle Selinus; Linnéuniversitetet; []

  7. 5. Numerical modeling of groundwater and air flow between compacted bentonite and fractured crystalline rock

    Author : Benoît Dessirier; Jerker Jarsjö; Andrew Frampton; Stefan Finsterle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Two-phase flow; porous media; fractured media; compacted bentonite; crystalline rock; numerical modeling; geological disposal; Physical Geography; naturgeografi;

    Abstract : The geological repository for final storage of spent nuclear fuel, envisioned by the Swedish Nuclear Fuel and Management Company (SKB), relies on several barriers: copper canisters deposited in holes in the floor of underground tunnels in deep bedrock, embedded in a buffer of compacted bentonite. The initially unsaturated buffer would take up water from the surrounding rock mass and swell to seal any potential gap. READ MORE
