  1. 1. Long-Term Simulation of Coastal Evolution

    Författare :Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

    Sammanfattning : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. LÄS MER

  3. 2. Linking lake variability, climate, and human activity in Basotu, Tanzania

    Författare :Lindsey Higgins; Lars-Ove Westerberg; Jan Risberg; Sarah Davies; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tanzania; crater lake; climate change; land-use change; water resources; environmental variability; diatoms; paleolimnology; chronology; Physical Geography; naturgeografi;

    Sammanfattning : Paleoenvironmental investigations establish important baseline knowledge of the natural variability of lake systems, to better understand human impacts on the landscape, and the effects of climate change on water resources. By combining long-term environmental history with investigations into modern land use patterns and climatological events, a wider perspective can be reached that has practical applications in water governance.

  4. 3. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability

    Författare :Shiyong Yu; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; tidal action; solar forcing; global meltwater pulse; North Atlantic storminess; climate changes; shoreline displacements; sea-level fluctuations; Littorina transgression; Baltic Sea; klimatologi;

    Sammanfattning : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. LÄS MER

  5. 4. Aquatic assessment in the Lake Tumba landscape, RDCongo : fish diversity and conservation

    Författare :Adele Mputu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The 80,000 km² Lake Tumba Landscape (LTL) is the only one of the 12 UN Priority Conservation Areas in Africa with a focus on freshwater ecosystems. Surprisingly little though is known about fish in this area. The objective of this thesis is to increase knowledge of fish occurrence in the LTL. LÄS MER

  7. 5. Stratigraphy and facies of Middle Silurian epicontinental carbonate platform deposits of Gotland, Sweden

    Författare :Mikael Calner; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysisk geografi; Geologi; Geology; physical geography;

    Sammanfattning : The Silurian foreland of Scandinavia included a vast epicontinental carbonate platform system of which the island of Gotland (Sweden) is an erosional remnant. This thesis treats the Late Wenlock succession (Cyrtograptus lundgreni, Pristiograptus dubius parvus, Gothograptus nassa, Colonograptus(?) praedeubeli, and the Co(?) deubeli zones), and emphasises the sedimentology and biostratigraphy of these deposits.
