  1. 1. Holocene lake-level changes in the Siljan Lake District – Towards validation of von Post’s drainage scenario

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Savvas Paradeisis-Stathis; [2020]
    Nyckelord :Lake Siljan; Dalarna; basin isolation; catastrophic drainage; early Holocene; lake sediments; XRF scanning; C N ratio; magnetic susceptibility; pollen; Ancylus Lake; Earth and Environmental Sciences;

    Sammanfattning : The Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. LÄS MER

  3. 2. 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.

  4. 3. Jökulhlaups: their associated landforms and landscape impacts

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

    Författare :Martin Bernhardson; [2011]
    Nyckelord :physical geography; geomorphology; Jökulhlaup; Sandur; Skeiðarársandur; naturgeografi; geomorfologi; Earth and Environmental Sciences;

    Sammanfattning : Glacial outburst floods also known as jökulhlaups are important features connected with glaciers globally. They may induce catastrophic floods as well as new landforms. LÄS MER

  5. 4. Estimation of the soil moisture distribution in the Tamne River Basin, Upper East Region, Ghana

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

    Författare :Per Asserup; Martin Eklöf; [2000]
    Nyckelord :physical geography; soil Moisture; wetness index; topography; hydrological modelling; GIS; geographical information systems; geomorphology; pedology; cartography; climatology; naturgeografi; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Sammanfattning : Northern Ghana experiences one dry season per year, but severe droughts may occur more infrequently. This is of concern to the local farmers of the Tamne River Basin (northeast Ghana) who depend on adequate rainfall amounts during the rainy season. Unfavourable precipitation amounts may lead to catastrophic consequences. LÄS MER
