  2. 1. Estimations of Hydrogeological Properties in Vulnerability and Risk Assessments

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

    Abstract : 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. READ MORE

  4. 2. 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. 3. Groundwater vulnerability assessment using process-based models

    Author : Riitta Lindström; Roger Thunvik; Pertti Vakkilainen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Database; Groundwater vulnerability; Hydrogeological environment; Process-based models; Penetration depth; Turnover time; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : The focus of this thesis is on groundwater vulnerability assessment by process-based simulation models and data acquisition for these assessments. A modelling system for intrinsic groundwater vulnerability assessment in water supply areas was developed, consisting of flow- and transport models for the unsaturated zone and the groundwater zone, coupled to a geographical informa-tion system.

  6. 4. A multidisciplinary approach: geophysics, hydrochemistry and hydrometeorology for addressing water security in semiarid alluvial fans

    Author : Andres Gonzales; Teknisk geologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysical methods; Hydrochemistry; Hydrometeorology; Bolivia; Alluvial fan;

    Abstract : Water security offers to the local population an adequate quality and quantity of water for health, economy, livelihoods and ecosystems. Hence, achieving basic levels of water security should be a priority in areas where access to fresh water is scarce. READ MORE
