  1. 6. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julia Cavell; [2022]
    Keywords : ;

    Abstract : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.

  3. 7. Rainwater Infiltration Model of the Chocaya Basin using Hydrus-1D

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

    Author : Alexander Bergman; Mire Persmark; [2020]
    Keywords : Rainwater Infiltration; Alluvial Plain; Chocaya Basin; Hydraulic Conductivity; Double Ring Infiltrometer DRI ; Hydrus-1D; Electrical Resistivity Tomography ERT ; Earth and Environmental Sciences;

    Abstract : The objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. READ MORE

  4. 8. A geophysical survey in the Chocaya Basin in the central Valley of Cochabamba, Bolivia, using ERT and TEM

    University essay from Lunds universitet/Geologiska institutionen

    Author : Hannes Pilser; [2020]
    Keywords : ERT; TEM; geophysics; Cochabamba; aquifer; Earth and Environmental Sciences;

    Abstract : The Chocaya Basin is situated in the north-western part of the Valley of Cochabamba, Bolivia, where a semi-arid climate prevails. The increasing population is dependent on local aquifers for drinking water and irrigation. Wells are used to extract water. READ MORE

  5. 9. 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

  6. 10. 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; Technology and Engineering; Earth and Environmental Sciences;

    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.
