  1. 1. Investigation of unknown groundwater flows to two leachate ponds at Hovgården

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Katja Nordström; [2023]
    Nyckelord :landfill; leachate; principle component analysis; PCA; polishing pond;

    Sammanfattning : The leaching of groundwater into two polishing ponds, the last step in the wastewater treatment process on Hovgarden waste facility, was examined. The focus of this study was to analyse the PFAS composition profile (fingerprint) to trace the leaching groundwater. LÄS MER

  3. 2. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow

    Master-uppsats, KTH/Energiteknik

    Författare :Max Hesselbrandt; [2021]
    Nyckelord :;

    Sammanfattning : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.

  4. 3. Data interpolation for groundwater modelling : How choice of interpolation method and sample size affect the modelling results

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Frida Agerberg; [2020]
    Nyckelord :Geohydrology; Groundwater; Modelling; Interpolation; SEEP W; Surfer; Geohydrologi; Grundvatten; Modellering; Interpolering; SEEP W; Surfer;

    Sammanfattning : Over the past several decades, the use of groundwater modelling has been increasing in order to better evaluate the complexities inherent in hydrogeological calculations. Information required for groundwater modelling is for example elevation of soil and bedrock layers, which often is collected by drilling. LÄS MER

  5. 4. Evaluation of Darcy Flow Velocities Obtained from Borehole Dilution Tests

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Johanna Lundin; [2019]
    Nyckelord :Single borehole dilution tests SBDT ; Darcy flow velocity; karst aquifer; porous aquifer; Donauried-Hürbe; Germany; Technology and Engineering;

    Sammanfattning : The project is part of a larger investigation of the water protection area Donauried-Hürbe. This area is a recharge zone used by one of Germany’s biggest water supply companies, the Zweckverband Landwasserversorgung (LW). LÄS MER

  7. 5. Thermal Performance Analysis of High Temperature Borehole Thermal Energy Storage Design from an Insulation Perspective

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Tobias Magnusson; Joel Ljunggren; [2019]
    Nyckelord :High Temperature Borehole Thermal Energy Storage; HT-BTES; Thermal Energy Storage; TRNSYS; Technology and Engineering;

    Sammanfattning : Thermal energy storage is a growing concept within the sector of energy production. The concept is based on storage of excess thermal energy, for usage during high demand, as a mean of reducing the need for new production. LÄS MER
