  1. 1. Excavating the Digital Landscape : GIS analyses of social relations in central Sweden in the 1st millennium AD

    Författare :Daniel Löwenborg; Paul Sinclair; Julian D. Richards; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; landscape archaeology; GIS; Iron Age; Västmanland; burial grounds; Vendel Period; Viking Age; territorial organisation; watersheds; statistical analysis; chronology; discriminant analysis; GWR; spatial analysis; perception; topography; AD 536; Fimbulvinter; property rights; crisis; historical ecology.; Archaeology; Arkeologi; Archaeology; Arkeologi;

    Sammanfattning : This thesis presents a number of GIS based landscape analyses that together aim to explore aspects of the social development in Iron Age Västmanland, central Sweden. From a perspective where nature and culture are seen as integrated in the landscape, differences in the relations to the physical landscape are interpreted as reflecting social organisation. LÄS MER

  3. 2. The role of roads on hydrological response : Modeling and assessment for Swedish watersheds

    Författare :Alireza Nickman; Per-Erik Jansson; Lars Rosen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GIS; Roads; Flooding; HEC-HMS; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Understanding the role of road networks in alteration of hydrological responses is crucial for maintaining the accessibility and durability of road infrastructures. Road construction is one of the most common man made disturbances to a landscape. LÄS MER

  4. 3. Modeling flow and sediment transport in water bodies and watersheds

    Författare :Muluneh Admass Mekonnen; Bijan Dargahi; Anders Wörman; Hans Bergh; Edward Buchak; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bed load transport model; ECOMSED; Hydrology; Hydrodynamics; Spectral Analysis; SWAT; Water engineering; Vattenteknik;

    Sammanfattning : The research focus is on the various modeling aspects of flow and sediment transport in water bodies and watersheds. The interaction of flow with a mobile bed involves a complex process in which various turbulent scales characterized by coherent structures cause a chaotic sediment motion. LÄS MER

  7. 5. Dissolved organic carbon in tropical watersheds : Linking field observation and eco-hydrological modelling

    Författare :Fabien Rizinjirabake; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic carbon DOC ; Rwanda; Land use land cover variability; Climate variability and change; Rukarara River Watershed; eco-hydrological modelling; field observation;

    Sammanfattning : Dissolved organic carbon (DOC) is a general description of the organic material dissolved in water. DOC is an important source of energy, carbon, and nutrient transfers from terrestrial to aquatic ecosystems. The export of DOC into aquatic ecosystems may contribute to the carbon balance of terrestrial ecosystems and to water degradation. LÄS MER
