  2. 11. Swash Processes and Dune Erosion: Emphasis on Vessel-Generated Waves

    Author : Li Erikson; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marklära; kartografi; klimatologi; Civil engineering; hydraulic engineering; geomorfologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; Naturvetenskap; Physical geography; Natural science; swash; erosion; vessel-generated waves; dunes; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastline changes as a result of exposure to vessel-generated waves has become a topic of increased research.

  4. 12. Leaf Area Index of Scandinavian Forests Methods Using in situ and Remotely Sensed Data

    Author : Helena Eriksson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geologi; fysisk geografi; Physical geography; geomorphology; Geology; physical geography; leaf aggregation; specific leaf area SLA .; Växtekologi; Plant ecology; Leaf area index LAI ; canopy reflectance models; spectral vegetation indices; remote sensing; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Abstract : This thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. READ MORE

  5. 13. Mountain vegetation in the Faroe Islands in a climate change perspective

    Author : Anna Maria Fosaa; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; klimatologi; marklära; Växtekologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; climate change.; Physical geography; Raunkiær´s life-forms; biodiversity; Vegetation zones; plant communities; Plant ecology; kartografi; geomorfologi;

    Abstract : This thesis is a study of the mountain vegetation in the Faroe Islands based on five altitudinal transects sampled during the period 1999-2001. The vegetation was studied on the basis of plant communities, life-forms and biodiversity of vascular plant species and is discussed in a climate change perspective. READ MORE

  6. 14. Global Changes and European Terrestrial Ecosystems

    Author : Emmanuel Gritti; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; European species; Climatic risk; pedology; cartography; climatology; Fysisk geografi; geomorphology; Physical geography; Vegetation modelling; Pollen analysis; Plant invasion; geomorfologi; marklära; kartografi; klimatologi; Global Changes;

    Abstract : Global environmental changes are topics of important societal concern and current scientific interest. These changes are driven by many different forcing and feedbacks occurring at various time and geographic scales and are largely influencing the various Earth systems. READ MORE

  7. 15. An Optimisation Approach to Cartographic Generalisation

    Author : Lars Harrie; Centrum för geografiska informationssystem (GIS-centrum); []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; incremental generalisation; multiple representation; least-squares method; optimisation; cartographic constraints; displacement; cartographic generalisation; graphic generalisation; map production; object-oriented spatial databases; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik;

    Abstract : Cartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. READ MORE
