  1. 1. 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

  3. 2. 1D and 2D Modelling of AMT and CSAMT Measurements from Swedish Lapland - A Case Study

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lisa Dossow; [2018]
    Keywords : audiomagnetotellurics; controlled source audiomagnetotellurics; Gällivare; Kiruna; time series processing; 1D and 2D inversion;

    Abstract : Audiomagnetotelluric measurements with (CSAMT) and without (AMT) a controlled source were performed near Gällivare and Kiruna in Swedish Lapland in order to retrieve representative conductivity models of the subsurfaces. Magnetotelluric transfer functions were gained from processed time series’ and subsequently inverted to generate the sought models successfully. READ MORE

  4. 3. 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; Earth and Environmental Sciences; Technology and Engineering;

    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. 4. Gravity and Magnetic Survey, Modelling and Interpretation in the Blötberget Iron-Oxide Mining Area, Bergslagen, Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Ezra Yehuwalashet; [2016]
    Keywords : Blötberget; gravity; Bouguer; magnetic; 3D inversion modelling; surface geology; ore deposit; Blötberget; gravimetri; Bouguer; magnetometri; 3D-modell; ytgeologi; malmfyndighet;

    Abstract : The Blötberget mining area, the focus of this MSc project, is located about 230 km northwest ofStockholm and 12 km southwest of the city of Ludvika (central Sweden). The mining area has beenknown since 1600 for its various types of mineralization particularly iron-oxide deposits (magnetite andhematite) with the mining commenced in 1944. READ MORE
