  1. 26. 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.

  3. 27. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanna Andersson; [2021]
    Keywords : geochemistry; loess; XRF; weathering; climate change; N-W France;

    Abstract : Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. READ MORE

  4. 28. Strukturkalkens inverkan på jordmotstånd : analys av mätningar på det horisontella och vertikala motståndet

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Claes Sjöberg; Jens Kårhammer; [2021]
    Keywords : strukturkalkning; dragkraftsbehov; jordmotstånd; penetrometermotstånd; aggregatbildning; lerjord; pH;

    Abstract : Genom tillförsel av strukturkalk, som är en jordförbättringsåtgärd till lerjord, kan flera positiva effekter uppnås. Forskning har tidigare visat att strukturkalkning kan ge stabilare aggregat, och kan bidra till minskat fosfor läckage samt bättre vatten och näringshållande förmåga. READ MORE

  5. 29. Contamination analysis of the landfill Rösaberg inerta massor : Risk assessment and investigation of the contaminant distribution

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Westander Lisa; [2020]
    Keywords : Landfill; MODFLOW; Risk assessment; Site-specific guidelines; Deponi; MODFLOW; Riskbedömning; Platsspecifika riktvärden;

    Abstract : The dispersion of contaminants deriving from landfills poses a risk to the surrounding environment and human health. Old landfills are treated with extra precaution, due to their poorer construction, less stringent operation and lack information regarding the waste content. Vetlanda municipality has identified 48 old landfills. READ MORE

  6. 30. Hydrogeological Prognoses in Infrastructure Projects : A Case Study of Stockholm Bypass, Hjulsta Norra

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Frida Grenholm; [2020]
    Keywords : Infrastructure; hydrogeology; groundwater; prognoses;

    Abstract : As cities expand, urban planning and efficient land use becomes more important and presents new challenges. A city that is exposed to these challenges is Stockholm, Sweden (Stockholms stad, 2018). READ MORE
