    Heinrich events are characterized by worldwide climate modifications. Over the Altiplano endorheic basin (high tropical Andes), the second half of Heinrich Stadial 1 (HS1a) was coeval with the highstand of the giant paleolake ...
  • Landformer på Mars 
    Gallis, Kristian Andre (Master thesis / Masteroppgave, 2006)
    Gjennom all tid har menneskene prøvd å få vite så mye om Mars som mulig. Gjennom århundrene har forskerne alltid brukt den mest avanserte teknologien i sin tid. Før Galileo Galilei kunne vi bare observere med det bare øyet, ...
  • Landslide Hazard Mapping in Norddal, Møre og Romsdal : A case study and review of landslide hazard mapping according to current requirements of the Norwegian Water Resources and Energy Directorate (NVE) 
    Walberg, Nils Arne K. (Master thesis / Masteroppgave, 2013)
    Skredfarekartlegging i Norge blir i dag i stor grad utført av eksterne selskaper på oppdrag fra Norges vassdrags- og energidirektorat (NVE), noe som fører til varierende tolkning av retningslinjer og detaljnivå. Målet med ...
  • Landslide magnitude-frequency analysis to better define warning criteria for warning levels in Sogn og Fjordane, Norway 
    Mongstad, Håvard (Master thesis / Masteroppgave, 2018)
    The county of Sogn og Fjordane in Western Norway has a climate and topography which makes it vulnerable for debris avalanches, debris flows, shallow slides and slush flows. The recently established landslide forecasting ...
  • Landslide occurrence as a response to large-scale synoptic weather types, precipitation and soil saturation in southern Norway 
    Jørandli, Lisa Østvik (Master thesis / Masteroppgave, 2016)
    Debris flows and debris slides/avalanches (weather-induced landslides) represent a significant threat to infrastructures and human habitation in Norway. They are triggered by a combination of high intensity rainfall, ...
