    Sammanfattning : Several debris flows have affected Åre municipality (Sw. Åre kommun) in the last 20 years. Jämtlandis a declared risk area for landslides and debris flows and there is an even higher probability oflandslides causing great damage around the Åre urban area. LÄS MER

  3. 2. Anticipating Glacier Lake Outburst Floods (GLOFs): an impact-based forecasting framework for managing GLOF risks in Nepal.

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Grace Muir; [2023]
    Nyckelord :Anticipatory Action; Impact-based Forecasting; Glacier Lake Outburst Flood; Nepal; Risk-informed Early Action; Prediction; Disaster Risk Management; Science General;

    Sammanfattning : Glacier lake outburst floods (GLOFs) are an increasingly documented threat across the Himalayan region, wherein Nepal is situated. GLOFs involve a rapid discharge of water from a lake situated at the side, front, within, beneath, or on the surface of a glacier. LÄS MER

  4. 3. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Alexander Lindblad; [2022]
    Nyckelord :Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

    Sammanfattning : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. LÄS MER

  5. 4. Post-Wildfire Debris Flows: Mapping and Analysis of Risk Factors in Western North America

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Annejet Tuinstra; [2021]
    Nyckelord :wildfires; debris flows; water repellent soil; North America; skogsbränder; jordskred; vattenavvisande jordlager; Nordamerika;

    Sammanfattning : Climate change is leading to in an increase in frequency and severity of wildfires, which in turn can result in the formation of runoff-initiated post-wildfire debris flows. This type of debris flows is, like most debris flows, triggered by heavy precipitation events. LÄS MER

  7. 5. Internal geology and emplacement processes of Kimberlites, Case Study from the Tsabong Kimberlite Field, Botswana

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Mpho Ndebele; [2020]
    Nyckelord :Kimberlites; Geology; Emplacement Processes; Botswana;

    Sammanfattning : The Crateceous (85 Ma) MK1 pipe is part of the Tsabong kimberlite cluster located approximately550km south west of Gaborone and geologically found within the Kapvaal Craton. The Tsabongkimberlite field consists of 86 known kimberlites. The MK1 pipe is the largest of this cluster at 140ha,1. LÄS MER
