  1. 1. Remote Sensing and GIS Applications for Groundwater Potential Assessment in Eritrea

    University dissertation from Stockholm : Byggvetenskap

    Author : Semere Solomon; KTH.; [2003]
    Keywords : Remote sensing; Geographic Information Systems; groundwater; geomorphology; Digital elevation model; lithology; hard rock; lineament; structures; hydrogeology; Eritrea;

    Abstract : 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. READ MORE

  2. 2. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Alireza Nickman; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; Flood; Moisture; Temperature; Groundwater; GIS; Uncertainity; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.

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

    University dissertation from Chalmers University of Technology

    Author : Per Sander; Chalmers tekniska högskola.; Chalmers University of Technology.; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geovetenskap; Earth sciences; groundwater assessment; remote sensing; lineaments; hard rock; GIS; Ghana; Botswana; probabilistic approach;

    Abstract : 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. 4. Remote Sensing of Forest Decline in the Czech Republic

    University dissertation from Lund University Press

    Author : Jonas Ardö; Lunds universitet.; Lund University.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Czech Republic; neural networks; sulphur dioxide; air pollution; Norway spruce; deforestation; forest decline; GIS; spectral characteristics; Remote sensing; Landsat; Ore Mountains; Geology; physical geography; Geologi; fysisk geografi;

    Abstract : Popular Abstract in Swedish Avhandlingen beskriver hur man med elektromagnetisk reflekterar strålning, registrerad från satelliter vilka cirkulerar runt jorden kan lokalisera och kvantifiera skador på barrskog i Tjeckien. Signifikanta samband mellan reflektans och barrförluster gör det mögligt att utföra översiktliga uppskattningar av dessa varrförluster med satellitdata. READ MORE

  5. 5. Spatial distribution of water resources and accessibility to water. The case of Bugesera district in Rwanda

    University dissertation from Kungsbacka : Geson

    Author : Jean Paul Dushimumuremyi; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Water resources; access to water; GIS; remote sensing; Bugesera; Rwanda;

    Abstract : This study deals with issues related to water resources and the accessibility to water in Bugesera district, a rural area of Rwanda. The research problem focuses on why people in Bugesera face perpetual problems related to water shortage. The research focuses on physical and socio-economic factors affecting people’s access to water. READ MORE
