  1. 16. Infiltration, hydrogeology, and heterogeneity - Management of pressure and flow: A case study for the Varberg tunnel project

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Lisa Risby; [2020-07-08]
    Nyckelord :short duration hydraulic tests; hydraulic conductivity; radius of influence; infiltration; heterogeneity; confined and unconfined aquifer;

    Sammanfattning : This thesis aims to describe a conceptual model of the sedimentology for Swedish (or nordic) conditions of heterogeneous aquifers but focus is on a case study in Varberg. This to facilitate the identification of main water-bearing units (e.g. LÄS MER

  3. 17. Hydrogeological Prognoses in Infrastructure Projects : A Case Study of Stockholm Bypass, Hjulsta Norra

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

    Författare :Frida Grenholm; [2020]
    Nyckelord :Infrastructure; hydrogeology; groundwater; prognoses;

    Sammanfattning : As cities expand, urban planning and efficient land use becomes more important and presents new challenges. A city that is exposed to these challenges is Stockholm, Sweden (Stockholms stad, 2018). LÄS MER

  4. 18. Rainwater Infiltration Model of the Chocaya Basin using Hydrus-1D

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

  5. 19. INFLUENCE OF CARBON CONTENT AND COOLING CONDITIONS ON THE THERMAL CONDUCTIVITY AND TENSILE STRENGTH OF HIGH SILICON LAMELLAR GRAPHITE IRON

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Gokul Ram; Vishnu Harikrishnan; [2020]
    Nyckelord :Lamellar cast iron; hypereutectic; eutectic; hypoeutectic; carbon; silicon; carbon equivalent; cooling rate; dendrites; graphite flakes; specific heat capacity; thermal expansion coefficient; thermal diffusivity; thermal conductivity; tensile strength; hydraulic diameter.;

    Sammanfattning : Much study has been carried out to determine the properties of Lamellar Graphite Iron (LGI) or grey iron and their relations to factors such as the cooling rate, the dendrite morphology, the pouring temperature, and so on. However, there hasn’t been much comprehensive study on the properties of LGI outside the generally used and accepted composition, with 1 to 3% Silicon. LÄS MER

  7. 20. 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
