  1. 11. A geophysical survey (TEM; ERT) of the Punata alluvial fan, Bolivia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Joakim Mårdh; [2017]
    Keywords : electromagnetic; geophysics; TEM; Punata; alluvial fan; Earth and Environmental Sciences;

    Abstract : The Punata alluvial fan, situated in central Bolivia (Valle Alto) between the Altiplano and the lowlands, is an important aquifer for the local rural population. Due to rapid development and population growth in the area, the demand for fresh water has increased in recent year. READ MORE

  3. 12. Measurement Strategies for Geoelectrical Tomography: Specialized Techniques for Multichannel Instruments

    University essay from Lunds universitet/Matematik LTH

    Author : David Belfrage; [2017]
    Keywords : Electrical resistivity tomography; tomography; optimization; Mathematics and Statistics;

    Abstract : How to select which measurements to make during a geoelectrical resistivity survey has been an active field of research for decades. Despite this techniques for optimizing the measurement sequences so as to take full advantage of the multichannel capabilities of modern state of the art equipment are scarce. READ MORE

  4. 13. Groundwater occurrence and quality in Bulawayo province, Zimbabwe

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Anton Nygren; Edvard Nordenskjöld; Erik Östblom; [2016]
    Keywords : total dissolved solids; salinity; electrical conductivity; electrical resistivity tomography; vertical electrical sounding; magnetic field; auger holes; saturated hydraulic conductivity;

    Abstract : This study focused on determining the groundwater flow paths in the crystalline subsurface rocks of the Bulawayo metropolitan, Zimbabwe, through analysing the discontinuities of the electrical properties of the ground, as well as in the magnetic field of the underlying rocks. Further, borehole water quality was analysed by measuring and mapping several chemical parameters, specifically TDS, salinity and the electrical conductivity. READ MORE

  5. 14. Water Well Investigations in the Nampula Province, Mozambique - A Minor Field Study

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Ekosystemteknik (CI)

    Author : Elin Olsson; [2016]
    Keywords : Geophysical borehole logging; resistivity; natural gamma radiation; Nampula; Mozambique; Technology and Engineering;

    Abstract : Access to clean water for drinking and sanitation is a human right. Today water scarcity is a large problem and inequality in access to safe water is a striking truth. READ MORE

  6. 15. A 2D Electrical Resistivity Survey of Palsas in Tavvavuoma, sub-arctic Sweden

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Per Marklund; [2014]
    Keywords : Palsas; permafrost; peat plateaus; resistivity; ert; geophysics; Tavvavuoma; Palsar; permafrost; torvplatåer; resistivitet; ert; geofysik; Tavvavuoma;

    Abstract : Electrical resistivity tomography (ERT) is a commonly used geophysical method to investigate permafrost in the mountain environment, but few studies have employed this method in a permafrost affected peatland. For this thesis, 5 ERT profiles were measured over 17 palsas and peat-plateaus in a palsa peatland environment in Tavvavuoma, northern Sweden, where the primary aim was to investigate the depth to the base of permafrost under the mounds.
