  1. 1. Slope processes and strength of material in silt rich ravines in Säterdalen, Sweden

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

    Författare :Pontus Westrin; Nils Melin; [2015]

    Sammanfattning : Slope processes are important to understand if we are to protect fragile environments. Every year slope development in weak soils put nearby infrastructure in risk zones of sliding and ravine erosion takes away field areal from farmers as they grow even larger. LÄS MER

    Sammanfattning : Mass balance processes in glaciers are important for determining the growth or retreat of ice. Calving, the mechanical breakage of ice bergs from a glacier front, is a poorly understood phenomenon. This process has great importance to the mass balance of many glaciers, for example on Antarctica and in the Arctic. A recent paper by Åström et al. LÄS MER
