  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. Finite Element Modeling of Installation Effects of Soil-Cement Columns

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anne Holtmeier; [2022]
    Keywords : Deep Mixing; Soil Stabilization; Installation; Finite Element Method; PLAXIS;

    Abstract : Since the 1970's deep mixing columns have been widely used all over the world to improve the performance of soft soil in regard to bearing capacity or deformation behaviour. They are installed by mixing a binding agent, e.g. cement, in situ with the soil. READ MORE

  4. 3. Using remote sensing and land abandonment as a proxy for long-term human out-migration. A Case Study: Al-Hassakeh Governorate, Syria

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Berit Mohr; [2021]
    Keywords : geography; GIS; remote sensing; Syria; vegetation indices; land abandonment; Earth and Environmental Sciences;

    Abstract : The topic of human migration and displacement has become more important in recent years and will continue to do so in the following decades. Voices become louder claiming that climate change is a driving factor for increased displacement and migration. READ MORE

  5. 4. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lotte Wendt; [2021]
    Keywords : active layer thickness; DInSAR; subsidence; permafrost; Zackenberg; CALM; Earth and Environmental Sciences;

    Abstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.

  6. 5. 2D Modelling of Geosynthetically Reinforced Piled Embankments : Calibration Methods in PLAXIS 2D & Review of Analytical Guidelines

    University essay from KTH/Jord- och bergmekanik

    Author : Maya Sleiman; [2021]
    Keywords : ;

    Abstract : This thesis focuses on the 2D modelling of Geosyntheticaly Reinforced Piled Embankments (GRPE) in PLAXIS 2D. In doing so, it explores two main aspects: 1) the calibration of Interface Stiffness Factors (ISFs) governing the soil-pile interaction of Embedded BeamRow (EBR) elements in PLAXIS 2D, and 2) the prospects and limitations of modelling geogrids (GR) in PLAXIS 2D when underlain by EBR elements; although several studies have validates the EBR element in modelling piles, none address the geogrid-EBR interaction and its implications on modelling GRPE systems.
