  1. 1. Evaluating DInSAR for measuring seasonal elevation dynamics at the Vissátvuopmi palsa mire complex in Northern Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : André Farjami; [2022-09-09]
    Keywords : ;

    Abstract : During recent years the palsa mires of Fennoscandia have reported to be undergoing extensive lateral degradation, and in a warming environment the palsa mires of Sweden among others are threatened to thaw completely by the end of this century. Since subarctic peatlands account for 30% of the global soil organic carbon storage, small degradation changes in these areas globally, can potentially change the greenhouse gas emissions on a worldwide scale.

  3. 2. Urban infrastructure inundation risk from permanent sea-level rise scenarios in London (UK), Bangkok (Thailand) and Mumbai (India): A comparative analysis

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shawn Pace; [2021]
    Keywords : Geography; GIS; Climate Change; Sea-Level Rise; Urban Infrastructure; DEM; London; Mumbai; Bangkok; Earth and Environmental Sciences;

    Abstract : Due to anthropogenically created climate change, global cities are facing inundation by rising sea levels. This study aimed to fill knowledge gaps in understanding the exposure of urban infrastructure such as roads, railways, buildings and parks to sea-level rise (SLR) scenarios, and how this would affect local populations.

Northern Swedish aeolian sand dunes have been impacted by climatic changes throughout time. READ MORE

  6. 5. Methods for rockfall risk assessment and estimation of runout zones: A case study in Gothenburg, SW Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Laura Catalina Agudelo Motta; [2020]
    Keywords : Rockfall hazard; rockfall simulation; Gothenburg; Fjällbo; runout zones; Earth and Environmental Sciences;

    Abstract : Rockfalls occur around Sweden every year and the country lacks a national risk evaluation and an adequate regulatory framework for construction related to this natural hazard. The aim of this study is to address this problem by mapping areas under possible threat of rockfalls, considering two fundamental aspects: i) identification of the source areas and ii) estimation of the runout zones.
