  1. 16. Broad-Scale Patterns in CDOM and Total Organic Matter Concentrations of Inland Waters – Insights from Remote Sensing and GIS

    Författare :Enass Said Al-Kharusi; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inlandwater; Remote sensing; Sentinel-2 MSI; CDOM; GIS; climate change;

    Sammanfattning : The rise in CDOM (coloured dissloved organic matter) is likely to be relatively more pronounced in remote northern regions. However, there is a lack of monitoring to confirm this. LÄS MER

  3. 17. Remote Sensing and Gis for Groundwater Assessment in Hard Rock Areas. Applications to Water Well Siting in Ghana and Botswana

    Författare :Per Sander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; probabilistic approach; GIS; remote sensing; Ghana; hard rock; Botswana; groundwater assessment; lineaments;

    Sammanfattning : Different types of remote sensing data have been evaluated in this thesis with respect to their potential use in groundwater assessment in hard rock areas. The primary objectives of the study have been (1) to evaluate the interpretation of groundwater indicators from high resolution satellite images and aerial photography and (2) to investigate how remote sensing interpretations subsequently can be integrated with other pertinent data, as a decision support in water well siting under difficult hydrogeological conditions.

  4. 18. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea

    Författare :Semere Solomon; KTH; []
    Nyckelord :Remote sensing; Geographic Information Systems; groundwater; geomorphology; Digital elevation model; lithology; hard rock; lineament; structures; hydrogeology; Eritrea;

    Sammanfattning : An integrated approach with remote sensing, GeographicInformation Systems (GIS) and more traditional fieldworktechniques was adopted to assess the groundwater potential inthe central highlands of Eritrea. Digitally enhanced colorcomposites and panchromatic images of Landsat TM and Spot wereinterpreted to produce thematic maps such as lithology andlineaments. LÄS MER

  5. 19. Challenges of renovating the Gothenburg multi-family building stock - An analysis of comprehensive building-specific information, including energy performance, ownership and affordability

    Författare :Mikael Mangold; Seppo Junnila; Sweden Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aging building stock; Energy performance certificate; Energy retrofitting; Equity; GIS; Göteborg; Measured energy usage; Multi-family dwellings; Social sustainability; Tenure;

    Sammanfattning : In Sweden and many European countries, the building stock increased at a rapid pace during the period of 1950-1975. This aging building stock is in need of renovation which is a challenge and an opportunity in reaching the energy performance targets as well as decreasing societal inequities. LÄS MER

  7. 20. Water quality modeling based on landscape analysis: importance of riparian hydrology

    Författare :Thomas Grabs; Jan Seibert; Kevin Bishop; Hjalmar Laudon; Brian McGlynn; Georgia Destouni; Irena Creed; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Water quality model; terrain analysis; geographical information system GIS; riparian zone; total organic carbon TOC; boreal catchments; Hydrology; Hydrologi; geografi med naturgeografisk inriktning; Physical Geography;

    Sammanfattning : Several studies in high-latitude catchments have demonstrated the importance of near-stream riparian zones as hydrogeochemical hotspots with a substantial influence on stream chemistry. An adequate representation of the spatial variability of riparian-zone processes and characteristics is the key for modeling spatio-temporal variations of stream-water quality. LÄS MER
