  1. 11. Stochastic Settlement Model Including Creep Effects : Simulation of Groundwater Induced Subsidence

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Pierre Wikby; Ragnar Andersson; [2020]
    Keywords : creep settlement; secondary compression; geotechnical uncertainty; EMBANKCO; groundwater drawdown; time-dependent settlement model; krypsättningar; Sekundärkompression; geoteknisk osäkerhet; EMBANKCO; grundvattensänkning; tidsberoende sättningsmodell;

    Abstract : When underground openings are constructed, groundwater inflow can occur, which might lead to ground settlements, namely in clay. In these types of construction projects, it is beneficial to be able to quantify risks related to these settlements. A framework developed by Sundell et al. (2019, Risk Analysis, Vol. READ MORE

  3. 12. Effects of 100 years of drainage on peat properties in a drained peatland forests in northern Sweden

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Mikaela Casselgård; [2020]
    Keywords : ash content; biodiversity; bulk density; carbon; climate; compaction; ditch; drainage; greenhouse gas emissions; groundwater level; isotopes; nitrogen; peatland; restoration;

    Abstract : Natural peatlands provide a small but persistent long-term carbon (C) sink. However, within the last century their extent in Sweden has declined by about 1.5-2.0 million hectares due to drainage activities. READ MORE

  4. 13. Internal geology and emplacement processes of Kimberlites, Case Study from the Tsabong Kimberlite Field, Botswana

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Mpho Ndebele; [2020]
    Keywords : Kimberlites; Geology; Emplacement Processes; Botswana;

    Abstract : The Crateceous (85 Ma) MK1 pipe is part of the Tsabong kimberlite cluster located approximately550km south west of Gaborone and geologically found within the Kapvaal Craton. The Tsabongkimberlite field consists of 86 known kimberlites. The MK1 pipe is the largest of this cluster at 140ha,1. READ MORE

  5. 14. Artificial Groundwater Injection : A Study of Groundwater Level Control in Swedish Infrastructure Projects

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Martin Kjellberg Skjenken; [2019]
    Keywords : Groundwater; Subsidence; Artificial Recharge; Artificial Groundwater injection; Climate Change; Numerical modelling; Infrastructure and Swedish Transport Administration; Grundvatten; marksättningar; Skyddsinfiltration; Framtida klimatförändringar; Infrastruktur; Numerisk modellering; Trafikverket;

    Abstract : This thesis sets out to increase the knowledge of artificial groundwater injection (AGWI) in Sweden on behalf of the Swedish Transport Administration. This has been done by firstly conducting a literature review which provided the background which comprises mainly groundwater theory and subsidence. READ MORE

  6. 15. Study on ongoing subsidence in Uppsala City using Sentinel-1 radar data

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Jonas Fryksten; [2019]
    Keywords : InSAR; PSI; precise leveling; validation; clay;

    Abstract : Many cities in Sweden are partly located on clay and because of that, some urban city centres are undergoing significant subsidence. To measure subsidence in cities, precise leveling has been the traditional technique, but the interest for the Persistent Scatter InSAR (PSI) technique has increased in the last years, in this application.
