  1. 21. Glacial lake flood hazard assessment and modelling : a GIS perspective

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

    Författare :Maimoona Zehra Jawaid; [2017]
    Nyckelord :moraine dammed lake; Himalayas; Bhutan; GIS; hazard assessment; dynamic flood model; glacial lake; Physical Geography; ecosystem analysis; digital elevation model; GEM; Earth and Environmental Sciences;

    Sammanfattning : High mountain regions have experienced decreased glacier stability due to varying climate conditions. As glaciers melt, they are being replaced by glacial lakes of different sizes, some of which are prone to outburst flooding, and have caused catastrophic damage to downstream settlements and infrastructure.

  2. 22. Near-Surface Energy Balance on an Alpine Rock Glacier: Murtèl-Corvatsch

    Master-uppsats, Uppsala universitet/Luft-, vatten och landskapslära

    Författare :Luisa Pruessner; [2017]
    Nyckelord :rock glaciers; energy balance; SNOWPACK; permafrost;

    Sammanfattning : This project investigates the near surface energy balance on the Murt`el-Corvatsch rock glacier in the Upper Engadine, Swiss Alps, using the 1D physical SNOWPACK model. A correct representation of the near surface energy balance is important to predict the long term evolution of permafrost below rock glaciers. LÄS MER

  3. 23. The mass balance and equilibrium line altitude trends of glaciers in northern Sweden

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

    Författare :Caroline Hall; [2017]
    Nyckelord :equilibrium line altitude ELA ; net mass balance; ablation; accumulation; glaciers; Sweden; climate; precipitation; temperature; Earth and Environmental Sciences;

    Sammanfattning : Glaciers are of extreme importance since they hold climatic data going back 2,000 years. Glaciers can provide important services such as ecosystem services, habitats, water runoff, and hydro-energy. They also affect the Earth’s processes and many feedback mechanisms. LÄS MER

  4. 24. Engineering Nature under Climate Change – Implications of Assisted Migration on Sustainable Development in Mountain Ranges

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Katelin Markcrow; [2017]
    Nyckelord :Sustainable development; assisted migration; climate change; biodiversity; mountain ranges; ethics; debate;

    Sammanfattning : The Planet has entered a new epoch - the Anthropocene; where human activities, such as mining for and burning of fossil fuels, land-use change, and industrialization are actively disrupting the planet’s state. The rate at which climate change is occurring as a result of human activity is unprecedented in recent millennia and poses many threats through drastic changes in rain fall patterns, rising sea level, retreating glaciers, and an increase in extreme weather events.

  5. 25. Optimering av den skandinaviska massbalansmetoden på Storglaciären, Kebnekaisemassivet

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper; Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hannah Fahlborg; Emma Flodin; [2017]
    Nyckelord :Mass balance; climate; Storglaciären; the scandinavian method; optimization; Massbalans; klimat; Storglaciären; skandinaviska metoden; optimering;

    Sammanfattning : Klimatförändringar har direkt påverkan på glaciärers tillväxt och avsmältning. Genom att studera glaciärers massbalans kan framtida riskbedömningar, för bland annat havsytans stigning, uppskattas. LÄS MER
