  1. 1. Movement of Foxfonna rock glacier in Svalbard between 2017-2019

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

    Författare :Elias Lundström; [2020]
    Nyckelord :rock glacier; Svalbard; UAV; photogrammetry; movement detection; permafrost; Earth and Environmental Sciences;

    Sammanfattning : The movement of a rock glacier located at the bottom of the Foxfonna glacier, Svalbard, Norway, was studied through the use of photogrammetry and feature tracking software, between the years of 2017-2019, as well as elevation changes between 2009 and 2019. This could aid in further knowledge about the rapid velocity changes of rock glaciers in a continuous permafrost environment. LÄS MER

  3. 2. Glacial history of the upper Drac Blanc catchment (French Alps)

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

    Författare :Felix Martin Hofmann; [2018]
    Nyckelord :Physical Geography; 10Be exposure dating; structure-from motion; geomorphological mapping; moraine; equilibrium line altitude; Alps; Earth and Environmental Sciences;

    Sammanfattning : Glacier advances in the Écrins massif (French Alps) during the Late Glacial and the Early Holocene are poorly constrained. Based on field observations, a high-resolution digital elevation model and an orthophoto, glacial landforms in the upper Drac Blanc catchment were mapped. LÄS MER

  4. 3. Periglacial and glacial landform mapping in the Las Veguitas catchment, Cordillera Frondal of the Andes (Argentina).

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Eirini Makopoulou; [2018]
    Nyckelord :Geomorphological map; thermokarst lakes; glaciers; GIS; Argentinian Andes; spatial and temporal analysis;

    Sammanfattning : The semi-arid and arid Andes of South America are characterized by large areas with glacial and periglacial environments. This study focusses on the distribution of glacial and periglacial landforms in the Las Veguitas catchment, Cordillera Frontal, Argentina. LÄS MER

  5. 4. 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.

  7. 5. 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
