  1. 1. Assessing groundwater vulnerability

    Författare :Lena Maxe; KTH; []
    Nyckelord :;

    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

  3. 2. Groundwater Vulnerability Assessment to pollution in Different Soil and Rock Materials

    Författare :Twana Abdullah; Nadhir Al-Ansari; Sven Knutsson; Jan Laue; Sabbar Alqaisi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Vulnerability; DRASTIC; VLDA; Modification; Soil Mechanics; Geoteknik;

    Sammanfattning : The augmentation of human population regularly corresponds with change in the land cover, including expansion of urban areas, which imposes increasing the available amount of domestic and drinking water. The study area, Halabja-Saidsadiq Basin, is situated in the Northeast of Iraq and is one of the major groundwater sources of the region. LÄS MER

  4. 3. Estimations of Hydrogeological Properties in Vulnerability and Risk Assessments

    Författare :Lars Rosen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; groundwater; Markov; conceptual model; Bayes; risk; vulnerability;

    Sammanfattning : The main objective of this thesis was to evaluate and develop approaches for hydrogeological vulnerability and risk assessments, starting with scant data and updating the results as new information becomes available. This work was performed within three separate projects between 1989 and 1995. LÄS MER

  5. 4. Groundwater resources in hard rock coastal terrains : Insights into heterogeneity and spatial variability

    Författare :Robert Earon; Bo Olofsson; Okke Batelaan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Crystalline Rock; Groundwater Balance; Kinematic porosity; Groundwater Recharge; Water Security; Coastal Aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Challenges regarding water security in hard rock coastal regions with limited soil cover are: a seasonal absence of recharge during times of peak residency, heterogeneity and variability of the fracture network, close proximity to saline water sources and spatially inconsistent storage and extraction. In areas where it is not feasible to connect residents to municipal water systems, a better understanding of the resilience of reservoirs is needed. LÄS MER

  7. 5. Strategic groundwater protection

    Författare :Cecilia Scharp; KTH; []
    Nyckelord :;

    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
