  1. 1. Processes of lateral moraine formation at a debris-covered glacier, Suldenferner (Vedretta di Solda), Italy

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Monika Rabanser; [2019]
    Nyckelord :Lateral moraines; Moraine genesis; Moraine stability; Debris-covered glaciers; Clast shape; Alps; Sedimentology; Glacier fluctuations; Earth and Environmental Sciences;

    Sammanfattning : Lateral moraines are key features of glacial landscapes in high-alpine mountain areas. Research on lateral moraine formation is mostly limited to clean-ice glaciers; lateral moraine formation at the margins of debris-covered glaciers is currently poorly understood in an Alpine and sedimentological context.

  2. 2. Closure of Lilla Bredsjön Tailings Dam : an Evaluation of the Long-Term Dam Safety Measures

    Master-uppsats, KTH/Vattendragsteknik

    Författare :Jenny Bramsäter; [2017]
    Nyckelord :tailings dams; seepage; pore pressure; slope stability; slip surfaces; long-term stability;

    Sammanfattning : The mining industry contributes to enormous amounts of waste all over the world, which places high demands on tailings dams. In Sweden, there are strict regulations regarding the management and treatment of tailings dams, but some dams that were built before these regulations existed still pose a threat to the environment.

  3. 3. 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.
