  1. 1. 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

  3. 2. Effects of Maintenance on the Efficiency of NBS for Urban Flood Management

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

    Författare :Julia Markström; [2023]
    Nyckelord :Stormwater management; Nature-Based Solutions NBS ; Maintenance; Efficiency; Runoff volume reduction; Dagvattenhantering; Natur-baserade lösningar; Underhåll; Effektivitet; Dagvattenreducering;

    Sammanfattning : As rain events are likely to intensify and the proportion of impervious areas in cities increases, greater demands are put on stormwater management. Nature-Based Solutions (NBS) have become more popular over the past decades to be integrated into the stormwater strategy in order to reduce the volume of runoff in cities. LÄS MER

  4. 3. Can Dwarf Galaxies Tell Us How the Milky Way Formed?

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Þóra Karlsdóttir; [2023]
    Nyckelord :Dwarf Galaxy; Milky Way; Physics and Astronomy;

    Sammanfattning : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations. LÄS MER

  5. 4. Estimation of flood risk and cost-effective mitigations : A case study in Tierp

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

    Författare :Anton Blomqvist; Stephanie The; [2023]
    Nyckelord :Flood risk assessment; EAD; CADSS; MIKE21;

    Sammanfattning : Climate change is predicted to alter the rainfall patterns in the future, and extreme rain events with large rainfall volumes will become more frequent and intense which increases the flood risk. A clear trend can be seen, where more and more people decide to relocate from rural to urban areas. LÄS MER

  7. 5. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Oskar Ahlstedt; [2022]
    Nyckelord :Avrinningsområde; översvämningsmodellering; peak-bidragande område; hydrograf; hyetograf; MIKE 21; regnintensitet; CDS-regn; Chicago Design Storm;

    Sammanfattning : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. LÄS MER
