11. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in 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
12. Strategic groundwater protection
Sammanfattning : 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. LÄS MER
13. Assessing groundwater vulnerability
Sammanfattning : Groundwater is protected to varying degrees by the overlyinggeological strata. Groundwater vulnerability assessment is anevaluation of how effective the geological material is atreducing pollutants. LÄS MER
14. Fluoride in surface water and groundwater in southeast Sweden : sources, controls and risk aspects
Sammanfattning : 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).

15. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas
Sammanfattning : 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. LÄS MER
