  1. 1. A Structural Analysis of the Fracture Sets in Gothenburg, Sweden: A Remote Sensing and Manual Lineament Approach

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jacek Krysik; [2023-05-22]
    Nyckelord :Remote sensing; Manual lineament analysis; Fractal analysis; Structural; Regional geology; LiDAR; Gothenburg region;

    Sammanfattning : The fracture-valley landscape within the Gothenburg region was analysed based on LiDAR-derived hillshade images as well as several sources of orthomosaics. Using a manual lineament interpretation approach and complimented with an objective fractal analysis software (FROST), the objective of the study was to characterise the regional fracture sets as well as attempt to link the sets to the complex regional geological history.

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

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Sammanfattning : 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.

  4. 3. Fracture characterization in magmatic rock, a case study of the Sosa-dyke (Neuquén Basin, Argentina)

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Nilsson Jim; [2020]
    Nyckelord :dyke; magmatic intrusion; fractures; Sosa dyke; permeability; intrusion; magmatisk intrusion; sprickor; Sosa intrusionen; permeabilitet;

    Sammanfattning : There are many examples worldwide were fossil magmatic intrusions influence the local water and energy supply. Due to that intrusions can act as a conductor and a reservoir, but also as a barrier for fluids and gases in the ground. The decisive feature between conductor or barrier in an intrusion is its fracture network. LÄS MER

  5. 4. Cleavage fracture toughness at varying specimen size and crack depth

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Håkan Jernberg; [2019]
    Nyckelord :;

    Sammanfattning : Cleavage fracture is one of the most severe failure modes in low alloy ferritic steel structures and the fracture toughness is strongly dependent on the size of the specimen, crack depth and temperature. This thesis investigates how the fracture toughness is affected under conditions that relates to size and constraint effects through a fracture mechanical experiment test series. LÄS MER

  7. 5. Framtagning av konceptuell modell för spridnings- och nedbrytningsmönster av en industriförorening med klorerade lösningsmedel

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Per Pettersson; [2019]
    Nyckelord :klorerade lösningsmedel; naturlig nedbrytning; naturlig avklingning; sprickplan; grundvatten;

    Sammanfattning : Klorerade lösningsmedel har sedan mer än ett halvsekel använts inom metallbearbetning, produktframställning och vid kemtvättning. Användningen har resulterat i spill och läckage med förorening som följd. I södra Sverige så återfinns en industritomt med en omfattande förorening av trikloreten. LÄS MER
