  1. 1. 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 facilitatethe identification of main water-bearing units (e.g. LÄS MER

  3. 2. 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)

    Författare :Alexander Bergman; Mire Persmark; [2020]
    Nyckelord :Rainwater Infiltration; Alluvial Plain; Chocaya Basin; Hydraulic Conductivity; Double Ring Infiltrometer DRI ; Hydrus-1D; Electrical Resistivity Tomography ERT ; Earth and Environmental Sciences;

    Sammanfattning : The objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. LÄS MER

  4. 3. 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; 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

  5. 4. 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; 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. 5. 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
