  1. 1. Artificial intelligence to model bedrock depth uncertainty

    University essay from KTH/Jord- och bergmekanik

    Author : Beatriz Machado; [2019]
    Keywords : Machine learning; Artificial intelligence; Kriging; prediction; algorithm.;

    Abstract : The estimation of bedrock level for soil and rock engineering is a challenge associated to many uncertainties. Nowadays, this estimation is performed by geotechnical or geophysics investigations. These methods are expensive techniques, that normally are not fully used because of limited budget. READ MORE

  2. 2. Petrophysic of the Host-rock to the Ore in the Lovisa Mine, Bergslagen

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Oscar Gilljam Päärt; [2019]
    Keywords : Petrophysics; density; magnetic volume susceptibility; natural remanent magnetization; Bergslagen; lithology; Petrofysik; densitet; magnetisk susceptibilitet; naturlig magnetisk remanens; Bergslagen; lithologi;

    Abstract : The Bergslagen region has three base-metal mines operating today, and one of them is the Lovisa mine, which host a Zn-Pb-Ag deposit. The Lovisa mine is located in the Guldsmedshyttan area north of Lindesberg. READ MORE

  3. 3. Groundwater flow paths in fractured crystalline bedrock : Electromagnetic VLF measurements and modelling of a groundwater basin in Svanberga, Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Rasmus Thunell; [2018]
    Keywords : Groundwater; modelling; geophysics; comsol; VLF;

    Abstract : Sweden is a country with a relatively high number of private wells, where about 1.2 million inhabitants in permanent housing and an equal amount in summer housing relies on private wells as their drinking water supply. At the same time the market for drinking water treatment products is unregulated regarding quality and requirements are needed. READ MORE

  4. 4. Interpretation of geophysical and geochemical data in a 3D geological model construction of a contaminated site

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

    Author : Haoyu Wei; [2018]
    Keywords : Halogenated hydrocarbon; Geophysics; DCIP; GeoScene3D; Groundwater chemistry; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : The Alingsås dry-cleaning facility is one of the heavily halogenated hydrocarbon contaminated sites in Sweden. The source of contamination dates back to the 1970s when a large scale tetrachloroethylene leakage outbroke inside the dry-cleaning building. READ MORE

  5. 5. Application of ERT and IP for localisation of chlorinated hydrocarbons at a former dry-cleaning facility

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

    Author : Hedda Jönsson; Anna Wiberg; [2017]
    Keywords : Chlorinated hydrocarbons; PCE; Hagforstvätten; Geophysics; Resistivity; Chargeability; Geological features; Man-made structures; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : At Hagforstvätten a dry-cleaning facility operated 1970 – 1993 and leached huge amounts of tetrachloroethene (PCE) to soil and groundwater. This study was conducted at the contaminated site and focused on applying the geophysical methods Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) to investigate if it was possible to locate source zone, degradation zones and groundwater plumes of PCE.
