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

   Författare :Nils Kellgren; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; groundwater exploration; hard rock; semi-arid; decision support; lineaments; GIS; remote sensing; borehole siting;

   Sammanfattning : 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. LÄS MER

3. 2. 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. 3. Hydrogeologic Studies on the Regional Scale: Risk Assessment and Decision Analysis

   Författare :David Wladis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; well data; decision analysis; lineaments; remote sensing; conceptual model; risk; groundwater; Europe; Sweden;

   Sammanfattning : Regional hydrogeologic studies are important components of environmental policy-making and as a basis of large construction projects. The structure of hydrogeologic studies on the regional scale is often complex, with a large number of steps and considerations. LÄS MER

5. 4. 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

7. 5. Geophysical targeting of Fe-oxide Cu-Au deposits in the northern fennoscandian sheild

   Författare :Alessandro Sandrin; Satu Mertanen; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics; Exploration Geophysics; Prospekteringsgeofysik;

   Sammanfattning : In the last decades Fe-Oxide Cu-Au deposits have been discovered and developed in Australia, South America and Canada. This class of mineral deposits is also present in northern Sweden and thus represents a potential target for improving the mineral production of the country. LÄS MER
