1. Groundwater occurrence and quality in Bulawayo province, Zimbabwe
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : 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

2. Mapping leachates and subsurface structures using different geophysical methods.
University essay from KTH/Mark- och vattenteknikAbstract : The enrichment of ore produces large amounts of sulfur and metal-rich residual waste called tailings, which need to be deposited and stored for a long time. When the tailing is oxidized, large amounts of protons and metals are dissolved and diffuse to the groundwater. READ MORE

3. Resistivity and IP measurements at the Bolmen Tunnel and Ådalsbanan, Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : In all tunnel construction projects geophysical methods are important as a foundation for engineering geological conceptual models. Detailed information about the condition and the physical properties of rocks at depth is desirable, and geophysical methods have the potential to exploit these properties. READ MORE

4. Measuring techniques of Induced Polarization regarding data quality with an application on a test-site in Aarhus, Denmark and the tunnel construction at the Hallandsås Horst, Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : It has been shown that surveys of Induced polarization (IP) often contain data of low quality, because it is highly sensitive against different noise sources. When measuring induced polarization, where the method uses multicore cables and continuous electrode sounding (CVES, Continuous Vertical Electrical Sounding), noise phenomena such as capacitive coupling effects have to be considered.
