1. 11. Evaluation of the applicability of geophysical methods when characterizing mine waste in Yxsjöberg, Sweden

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

   Författare :Palo Matilda; [2021]
   Nyckelord :geophysics; Yxsjöberg; mine tailings;

   Sammanfattning : Smaltjärnen tailings repository located in Yxsjöberg, Sweden, attracts researchers with questions regarding characterization and potential re-mining. This thesis continuous geophysical characterization done by researchers from the Exploration Geophysics department at Luleå University of Technology but using new data from 2019. LÄS MER

3. 12. Automatic velocity estimation in GPR data and migration

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Christofer Jonason; [2020]
   Nyckelord :;

   Sammanfattning : Ground Penetrating Radar is a widely used technique for detecting objects in the subsurface. However, the objects typically appear as hyperbolic curves in the raw data's time domain. Therefore, the size and the location of the objects are hard to interpret from the raw data. LÄS MER

4. 13. Interpolation and visualization of sparse GPR data

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Rickard Sjödin; [2020]
   Nyckelord :GPR; Ground Penetrating Radar; Interpolation;

   Sammanfattning : Ground Penetrating Radar is a tool for mapping the subsurface in a noninvasive way. The radar instrument transmits electromagnetic waves and records the resulting scattered field. Unfortunately, the data from a survey can be hard to interpret, and this holds extra true for non-experts in the field. The data are also usually in 2. LÄS MER

5. 14. Evaluating the potential of artificial infiltration to increase groundwater storage using MIKE SHE : A case study in northern Storsudret, Gotland

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Sara Schmidt; Per Uppsäll; [2020]
   Nyckelord :Groundwater modelling; hydrogeology; aquifer assessment; freshwater resources;

   Sammanfattning : The island of Gotland, Sweden, is struggling with supplying the population with freshwater during summers. At the same time as the demand increases during these months, the warm weather and geological conditions prevent sufficient volumes of groundwater to recharge. LÄS MER

7. 15. Movement of Foxfonna rock glacier in Svalbard between 2017-2019

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Elias Lundström; [2020]
   Nyckelord :rock glacier; Svalbard; UAV; photogrammetry; movement detection; permafrost; Earth and Environmental Sciences;

   Sammanfattning : The movement of a rock glacier located at the bottom of the Foxfonna glacier, Svalbard, Norway, was studied through the use of photogrammetry and feature tracking software, between the years of 2017-2019, as well as elevation changes between 2009 and 2019. This could aid in further knowledge about the rapid velocity changes of rock glaciers in a continuous permafrost environment. LÄS MER
