  2. 11. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea

    Author : Semere Solomon; KTH; []
    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

  4. 12. Strategic groundwater protection

    Author : Cecilia Scharp; KTH; []
    Keywords : ;

    Abstract : Groundwater is an undervalued natural resource that isexperiencing a large number of threats to both its quantity andquality. Different types of land-use activities releasepotentially harmful substances that may be transported down tothe groundwater and have a negative impact on its quality. READ MORE

  5. 13. Assessing groundwater vulnerability

    Author : Lena Maxe; KTH; []
    Keywords : ;

    Abstract : Groundwater is protected to varying degrees by the overlyinggeological strata. Groundwater vulnerability assessment is anevaluation of how effective the geological material is atreducing pollutants. READ MORE

  6. 14. Fluoride in surface water and groundwater in southeast Sweden : sources, controls and risk aspects

    Author : Tobias Berger; Mats E. Åström; Pasi Peltola; Henrik Drake; Olle Selinus; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorine; fluoride; water-rock interaction; granite; crystalline bedrock; surface water; groundwater; Götemar; drinking water quality; aluminium; speciation; fluorosis; PBA; Miljövetenskap; Environmental Science;

    Abstract : The aim of this thesis is to determine the sources, controls and risk aspects of fluoride in surface water and groundwater in a region of southeastern Sweden where the fluorine-rich 1.45 Ga circular Götemar granite (5 km in diameter) crops out in the surrounding 1.8 Ga granites and quartz monzodiorites (TIB rocks).

  7. 15. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas

    Author : Jonas Sundell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; urban hydrogeology; pore pressure reduction; subsidence; geostatistics; groundwater leakage; soft soil; groundwater drawdown; spatial variability; settlement; probabilistic; risk assessment;

    Abstract : Groundwater drawdown induced ground subsidence is a severe problem in many regions around the world. Leakage of groundwater into a sub-surface construction, resulting in drawdown and subsequent subsidence, can lead to immense damage costs on buildings and installations in urban areas. READ MORE
