  1. 1. Multi-Data Approach for Subsurface Imaging: Combining Borehole and GPR- Data for Improved Analysis

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Pontus Yngvesson; [2023]
    Nyckelord :Geofysik; Geoteknik; GPR; Borrhål; Dataanalys; Markradar;

    Sammanfattning : The investigation to understand the subsurface and its features has long been asubject of interest for various fields, including fields such as archaeology and infras-tructure projects. However, traditional excavation methods are often costly and time-consuming. LÄS MER

  3. 2. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Ellen Lundin; Lovisa Liljenberg; [2023]
    Nyckelord :LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

    Sammanfattning : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. LÄS MER

  4. 3. Evaluation of structurally controlled rockfall hazard for underground excavations in seismically active areas of the Kiirunavaara mine

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Manuel Alberto Fuentes Espinoza; [2023]
    Nyckelord :Structurally controlled rockfalls; rockfalls due to seismic shaking; sublevel caving; fork layout; Unwedge; wedge analysis; deterministic analysis; probabilistic analysis;

    Sammanfattning : Sublevel caving operations at great depths are subjected both to large stress concentrations that are redistributed as the mining front progresses and to mining-induced seismicity. This is the case for Kiirunavaara mine, Sweden’s largest underground mine. LÄS MER

  5. 4. Towards an Archaeology of Disaster : Opportunities and Difficulties

    Master-uppsats, Linnéuniversitetet/Institutionen för kulturvetenskaper (KV)

    Författare :Bex Bodén; [2023]
    Nyckelord :Cultural heritage management; cultural resource management; disaster; disaster archaeology; disaster risk management; disaster risk prevention; emergency relief; forensic archaeology;

    Sammanfattning : This thesis examines the role of archaeology and its contribution to emergency relief work in areas struck by a disastrous event. At a time in our contemporary society where we may be extra vulnerable against disasters, archaeology can help us both prevent and reduce the risks of disasters. LÄS MER

  7. 5. Processing of ERT data from Stabilised Columns

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Mårten Petersson; [2023]
    Nyckelord :inversion; ERT; quality control; jet grouting; aarhusinv; Technology and Engineering;

    Sammanfattning : Modern construction sites are associated with high demands on suitable soil conditions, resulting in geotechnical challenges that can be solved using soil stabilisation techniques. The reliability of these techniques is tested using different quality assurance methods. LÄS MER
