  1. 1. EFFEKTER PÅ UPPSTRÖMSSTABILITETEN I FYLLNINGSDAMMAR : Ändrade porvattentryck till följd av cykliska magasinsnivåer

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

    Författare :Emma Widén; [2024]
    Nyckelord :Vattenfluktuationer; Släntstabilitet; Porvattentryck; Tolererat fel; Finita elementmetoden;

    Sammanfattning : Hydropower is one of the few energy sources with the ability to store a resource and thus regulate electricity production. When the water level in a reservoir changes, this affects the pore water pressures in the dam. LÄS MER

  3. 2. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance

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

    Författare :Clara Eklund; [2023]
    Nyckelord :PFAS; Groundwater modeling; FEFLOW; Python; Machine learning; Technology and Engineering;

    Sammanfattning : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. LÄS MER

  4. 3. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

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

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

  5. 4. Jet Grout Bottom Plug in Deep Excavations : Numerical Analysis of a Tunnel Project

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Ida Schjelderup; [2022]
    Nyckelord :Jet grouting; jet grout bottom plug; cut-and-cover tunnel; tunnel design;

    Sammanfattning : This master thesis has investigated the performance of a deep excavation with a jet grout bottom plug used to prevent bottom heave and hydraulic uplift failure. The concept of a jet grout plug as a structural and sealing component in a specific case was studied, namely one of the tunnel sections of The West Link tunnel project in Gothenburg. LÄS MER

  7. 5. Thermal-hydraulic safety analysis of the HTTU and GEMINI+ cores in TRACE

    Master-uppsats, KTH/Fysik

    Författare :Eva Joosten; [2022]
    Nyckelord :HTGR; TRACE; Thermal-Hydraulics; Safety; Heat Transfer; HTGR; TRACE; Termisk-Hydraulik; Säkerhet; Värmeöverföring;

    Sammanfattning : With the coming of Generation IV systems, there is a need for thermal-hydraulic codes to model such advanced reactors. Codes for High Temperature Gas-cooled Reactors (HTGRs) already exist, but often suffer from insufficient validation and little user experience. LÄS MER
