  1. 21. The Geothermal Potential in Isla Campuzano, Nicaragua

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

    Author : Louise Selméus; Manuela Stierna; [2017]
    Keywords : Geothermal Potential; Geochemistry; Geological Mapping; ICP-OES; QGIS; Hot Springs; Waters Samples; Na-K-Ca Geothermometer; Medium Enthalpy; Nicaragua.; Technology and Engineering;

    Abstract : Nicaragua has a geothermal potential of 1519 MW (CNE 2001) due to its volcano chain created by the tectonic activity between the Cocos plate and the Caribbean plate. The Ministry of Energy and Mines in Nicaragua has the ambition to have 91% of Nicaraguas energy consumption from renewables energy for 2027 where geothermal energy will constitute 22%. READ MORE

  3. 22. TEM investigation on Challapampa aquifer, Oruro Bolivia

    University essay from Lunds universitet/Geologiska institutionen

    Author : Måns Larsson; [2016]
    Keywords : kartering; survey geofysik; sedimentologi; geology; hydrogeology; geophysics; sedimentary; geologi; hydrogeologi; Earth and Environmental Sciences;

    Abstract : I denna studie utfördes en TEM (transient elektromagnetisk) undersökning på den Bolivianska altiplanon, norr om staden Oruro. I Oruro finns det ett underskott av dricksvatten och deras huvudsakliga vattenförsörjning kommer från aquiferen Challapampa. READ MORE

  4. 23. Evaluation of DC resistivity and time-domain IP tomography for bedrock characterisation at Önneslöv, Southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Daniel Preis Bergdahl; [2016]
    Keywords : bedrock; Cole-Cole; resistivity; induced polarization; dyke; weathering; Earth and Environmental Sciences;

    Abstract : For both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. READ MORE

  5. 24. Modeling groundwater flow and PFOS transport. : A case study at the old fire drill site of Bromma Stockholm Airport.

    University essay from KTH/Mark- och vattenteknik

    Author : Joakim Persson; Niklas Andersson; [2016]
    Keywords : Bromma Stockholm Airport; PFOS; Visual MODFLOW; Geophysics;

    Abstract : At Bromma Stockholm Airport, fire drills have previously been performed at a location outside the current airport confinements. Fire drills were performed with extinguisher foams containing toxic perfluorooctanesulfonic acid (PFOS), which have polluted the site. Harmful effects of PFOS include but are not limited to damages to the endocrine system. READ MORE

  6. 25. A High Order Finite Difference Method for Simulating Earthquake Sequences in a Poroelastic Medium

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Kim Torberntsson; Vidar Stiernström; [2016]
    Keywords : numerical analysis; numerical methods; numerical modeling; SBP-SAT; finite differences; high performance computing; geophysics; geomechanics; poroelasticity; fault mechanics; induced seismicity;

    Abstract : Induced seismicity (earthquakes caused by injection or extraction of fluids in Earth's subsurface) is a major, new hazard in the United States, the Netherlands, and other countries, with vast economic consequences if not properly managed. Addressing this problem requires development of predictive simulations of how fluid-saturated solids containing frictional faults respond to fluid injection/extraction. READ MORE
