  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. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow

    University essay from KTH/Energiteknik

    Author : Max Hesselbrandt; [2021]
    Keywords : ;

    Abstract : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.

  4. 3. Elastic properties of the Singö zone from a discrete approach

    University essay from KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Author : Amanda Åkerlind; [2019]
    Keywords : Elastic properties; deformation zones; Forsmark; Singö zone; DFN; Deformationsegenskaper; deformationszoner; Forsmark; Sinözonen; DFN;

    Abstract : A rock mass is characterised by the properties of the intact rock and the fractures. Considering the impact of both constituents is of vital importance for assessing the behaviour of the rock mass. In particular in the case of complex or heterogeneous rock mass compositions.

  5. 4. The Impact of Fracture Orientation on the Choice of Grout Fan Geometry - a Statistical Analysis

    University essay from KTH/Jord- och bergmekanik

    Author : Fredrik Osterman; [2019]
    Keywords : Rock Fissure Grouting; Grout Fan Geometry; Geology; Discrete Fracture Network; Sprickinjektering i berg; skärmgeometri; geologi; diskreta spricknätverk;

    Abstract : Water ingress into rock tunnels is a problematic phenomenon – especially in urban areas – as a lowered groundwater table may cause harmful settlements. Furthermore, too much ingress can be an incentive for the environmental court to halt the tunnel process, in order to protect the nature as part of a national interest. 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
