  1. 1. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Johanna Bergström; [2023-09-15]
    Keywords : Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Abstract : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. READ MORE

  3. 2. Enhancing Geophysical Applications with Electrical Resistivity Tomography Inversion : Uncovering the mysteries that lies beneath us

    University essay from Umeå universitet/Institutionen för fysik

    Author : Anton Morian; [2023]
    Keywords : Resistivity inversion; Filtering; 3D visualisation;

    Abstract : Geophysical methods have been widely used to investigate the subsurface in various ap-plications, such as mineral exploration, geotechnical and environmental studies. Among these methods, electrical resistivity tomography (ERT) has gained popularity due to its non-invasive and high-resolution capability in mapping subsurface resistivity variations. READ MORE

  4. 3. Processing of ERT data from Stabilised Columns

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

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

    Abstract : 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. READ MORE

  5. 4. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Edvin Nilsagård; Rebecka Knutsson; [2022]
    Keywords : ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Abstract : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. READ MORE

  6. 5. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Eduardo Garcia Cañas; [2022]
    Keywords : HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Abstract : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. READ MORE
