  1. 1. 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

  3. 2. Integration of geology with geophysics : Case studies from Svalbard

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sofia Rylander; Anna Sterley; [2022]
    Keywords : Gravity Measurements; Magnetic Measurements; Anomalies; Seismic; Fault Zones; Svalbard;

    Abstract : This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Basin (CSB) and across the Billefjorden Fault Zone (BFZ). READ MORE

  4. 3. Integration of Borehole, Ground, and Airborne Data to Improve Identification of Areas With Quick Clays in Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Oskar Rydman; [2021]
    Keywords : TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Landslides; Frastad; TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Jordskred; Fråstad;

    Abstract : The main focus of the project was the comparison of results from a new towed transientelectromagnetic (tTEM) data set with existing data including airborne transient EM(ATEM), radio magnetotellurics (RMT), cone penetration test with resistivity (CPT-R),geotechnical interpretations and geological observations in a quick clay landslide site atFråstad close to Lilla Edet in south-west Sweden. The tTEM data set was processedand inverted twice in the software Aarhus workbench using different inversion constraintsand settings. READ MORE

  5. 4. 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

  6. 5. 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
