  1. 1. Terrain Modelling with GIS for Tectonic Geomorphology Numerical Methods and Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Gyözö Jordan; Uppsala universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Sammanfattning : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. LÄS MER

  2. 2. Landscape partitioning and burial processes of soil organic carbon in contrasting areas of continuous permafrost

    Detta är en avhandling från Stockholm : Department of Physical Geography, Stockholm University

    Författare :Juri Palmtag; Stockholms universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil organic carbon; total nitrogen; permafrost; cryoturbation; geomorphology; land cover classification; slope processes; texture; upscaling; carbon nitrogen ratio; naturgeografi; Physical Geography;

    Sammanfattning : Recent studies have shown that permafrost soils in the northern circumpolar region store almost twice as much carbon as the atmosphere. Since soil organic carbon (SOC) pools have large regional and landscape-level variability, detailed SOC inventories from across the northern permafrost region are needed to assess potential remobilization of SOC with permafrost degradation and to quantify the permafrost carbon-climate feedback on global warming.

  3. 3. Accident Risk and Environmental Assessment Development of an Assessment Guideline with Examination in Northern Scandinavia

    Detta är en avhandling från Uppsala : Kulturgeografiska institutionen

    Författare :Markus Lundkvist; Uppsala universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geography; accident; risk; hazard; environmental assessment; geomorphology; railway; road; avalanche; debris flow; rock fall; slush flow; torrent; moose; reindeer; environmental impact assessment; proposal alternatives; Kiruna; Narvik; Geografi; NATURAL SCIENCES Earth sciences Other earth sciences; NATURVETENSKAP Geovetenskap Övrig geovetenskap;

    Sammanfattning : In environmental impact assessment (EIA), accident risk should be considered as one impact. However, few studies have compared assessed risk levels with documented accidents. There is thus a need for assessing accuracy of risk assessment methodologies. LÄS MER

  4. 4. The sensitivity of Swedish alpine lakes to hydro-climatic changes during the Late Holocene

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Författare :Annika Berntsson; Stockholms universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alpine lake sediments; temperature reconstruction; precipitation; catchment erosion; chironomids; oxygen isotopes; XRF core scanning; geomorphology; grain size analysis; Quaternary Geology; kvartärgeologi;

    Sammanfattning : The thesis objective is to use lake sediments to investigate the relationships between chironomids, as proxy for temperature, and δ18O and minerogenic in-wash, as precipitation proxies, in northern Sweden during the Late Holocene. Three lakes along a N–S transect in the Scandes were studied using biological, geochemical and physical sediment properties, together with numerical methods. LÄS MER

  5. 5. Marginal behaviour of the last Scandinavian Ice Sheet during its final termination and deglaciation over Northeastern Germany

    Detta är en avhandling från Quaternary Sciences, Department of Geology, Lund University

    Författare :Joachim Albrecht; Lunds universitet.; Lund University.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; Marginal dome; Deglaciation; Clast lithology; Clast fabric; Germany; Pomeranian; Weichselian; Lithostratigraphy; marklära; kartografi; klimatologi; Sedimentology; Sedimentologi;

    Sammanfattning : Popular Abstract in Swedish Svensk populärvetenskaplig sammanfattning Kvartärtidens avlagringar döljer mycket och detaljerad information om palaeoklimatet och de lämpar sig därför väl för att modellera palaeoklimatets förändringar. Inlandsisar är av avgörande betydelse för klimatet under kvartärtiden. LÄS MER
