  1. 1. 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

  3. 2. Inversion of SkyTEM Data Based on Geophysical Logging Results for Groundwater Exploration in Örebro, Sweden

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Andrée Kindlund; [2021]
    Nyckelord :SkyTEM; hydrogeophysics; geophysical logging; A priori; groundwater exploration;

    Sammanfattning : Declining groundwater tables threatens several municipalities in Sweden which drinking water is collected from. To ensure a sound drinking water supply, the Geological Survey of Sweden has initiated a groundwater exploration plan. LÄS MER

  4. 3. Evaluation of DC resistivity and time-domain IP tomography for bedrock characterisation at Önneslöv, Southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Daniel Preis Bergdahl; [2016]
    Nyckelord :bedrock; Cole-Cole; resistivity; induced polarization; dyke; weathering; Earth and Environmental Sciences;

    Sammanfattning : For both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. LÄS MER

  5. 4. Spectral time domain induced polarization : factors affecting spectral data information content and applicability to geological characterization

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Azadeh Rezvani; [2015]
    Nyckelord :Liikavaar; geology; geophysics; resistivity; induced polarization; Aititk mine; AarhusInv; Earth and Environmental Sciences;

    Sammanfattning : The geo-electrical survey (resistivity and induced polarization) with different settings, arrangements, time base, spreads and waveforms (50% and 100% duty cycle waveform) was carried out over the Liikavaara depo-sit, near the Aitik mine, in northern Sweden and all the measured data was inverted in two different softwares: Res2Dinv and AarhusInv. Surveys of induced polarization (IP) often contain data of low quality, due to the high sensitivity against noise sources and coupling effects. LÄS MER
