  1. 1. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  3. 2. Feasibility of Enhanced Geothermal Systems in the Precambrian crystalline basement in SW Scania, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Hanna Kervall; [2021]
    Keywords : EGS; deep drilling; geothermal; petrology; petrophysical properties; Sveconorwegian; Earth and Environmental Sciences;

    Abstract : The ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E. READ MORE

  4. 3. Saltwater Intrusion in Fractured Crystalline Bedrock Aquifer. - A Case Study on Koster Islands, SW Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Sibhat Afewerki; [2019-10-30]
    Keywords : saltwater intrusion; fractured bedrock aquifers; DRASTIC; vulnerability mapping; Koster Islands; slatvattenintrång; Akvifer i uppsprucken berggrund; sårbarhetskartläggning; Kosteröarna;

    Abstract : Saltwater intrusion (SWI) is one of the significant threats in many coastal areas, mainly driven by anthropogenic hazards (over-pumping) and climate change (sea level rise). So far, there have been extensive research and techniques to understand and minimize SWI. READ MORE

  5. 4. Groundwater flow paths in fractured crystalline bedrock : Electromagnetic VLF measurements and modelling of a groundwater basin in Svanberga, Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Rasmus Thunell; [2018]
    Keywords : Groundwater; modelling; geophysics; comsol; VLF;

    Abstract : Sweden is a country with a relatively high number of private wells, where about 1.2 million inhabitants in permanent housing and an equal amount in summer housing relies on private wells as their drinking water supply. At the same time the market for drinking water treatment products is unregulated regarding quality and requirements are needed. READ MORE

  6. 5. Site Application of a Channel Network Model for Groundwater Flow and Transport in Crystalline Rock

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Jonas Pedersen; [2018]
    Keywords : channel network models; discrete fracture networks; model calibration; groundwater flow and transport;

    Abstract : Groundwater flow and transport in deep crystalline rock is an important area of research. This is partly due to its relevance for constructing a long term repository for storing radioactive spent nuclear fuel in deep bedrock. READ MORE
