  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. 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.

  3. 3. 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; neural networks; Czech Republic; sulphur dioxide; air pollution; Norway spruce; deforestation; forest decline; GIS; spectral characteristics; Remote sensing; Landsat; Ore Mountains; Geology; physical geography; Geologi; fysisk geografi;

    Abstract : This thesis describes the localisation and quantification of deforestation and forest damage in Norway spruce forests in northern Czech Republic using Landsat data. Severe defoliation increases the spectral reflectance in all wavelength bands, especially in the mid infrared region. READ MORE

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

    University dissertation from Geson

    Author : Jean Paul Dushimumuremyi; Göteborgs universitet.; University of Gothenburg.; [2009]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Kulturgeografi; Human geography; 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

  5. 5. Applicability of Remote Sensing Techniques to Groundwater Exploration in Semi-Arid Hard Rock Terrain - A Systematic Approach

    University dissertation from Chalmers University of Technology

    Author : Nils Kellgren; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geovetenskap; Earth sciences; remote sensing; GIS; groundwater exploration; borehole siting; semi-arid; hard rock; lineaments; decision support;

    Abstract : Groundwater exploration in hard rock terrain involves complex decisions, attributable to a lack of reliable data and the heterogeneous nature of the geological environment. Targets for drilling of boreholes are commonly selected on the basis of knowledge, or perceptions, of groundwater occurrence in a specific area. READ MORE
