  1. 6. Estimating Groundwater Availability and Variability in Kilombero Valley, Tanzania

    University essay from Stockholms universitet/Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Maja Hemlin Söderberg; [2014]
    Keywords : ;

    Abstract : Freshwater resources are subject to increasing pressure from a local to global scale. For many parts of the world groundwater is central to increasing water and food security. This is especially the case in regions such as the Kilombero Valley, Tanzania with highly variable or seasonal climates resulting in irregular access to surface water. READ MORE

  3. 7. Risk management of groundwater drawdown in settlement sensitive areas.

    University essay from KTH/Mark- och vattenteknik

    Author : Victoria Tisell; [2013]
    Keywords : Groundwater model; Settlement; Crystal Ball with Monte Carlo simulation; Risk analysis; Deterministic; Probabilistic;

    Abstract : A new method for estimation of risks at settlement calculations is presented. By quantifying uncertainties of settlement calculations, it is possible to make risk analysis and to compare the costs of risk reducing efforts with the benefit these efforts would lead to. READ MORE

  4. 8. Evaluation of Long-term Impact of Coal Mining in Zambezi River Basin in Mozambique

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

  5. 9. Exploring a Water Balance Method on Recharge Estimations in the Kilombero Valley, Tanzania

    University essay from Institutionen för naturgeografi och kvartärgeologi (INK)

    Author : Sandra Fischer; [2013]
    Keywords : water balance; kilombero;

    Abstract : Simple models that require little input data and are easy to use is the ideal case within hydrology. Basic water balance principles often represent such approaches as the method on rainfall-runoff relationship developed by Sutcliffe et al. in India in 1981. READ MORE

  6. 10. A comparably robust approach to estimate the left-censored data of trace elements in Swedish groundwater

    University essay from Statistiska institutionen

    Author : Cong Li; [2012]
    Keywords : groundwater; left-censored data; the EM algorithm; maximum likelihood estimation;

    Abstract : Groundwater data in this thesis, which is taken from the database of Sveriges Geologiska Undersökning, characterizes chemical and quantitative status of groundwater in Sweden. The data usually is recorded with only quantification limits when it is below certain values. Accordingly, this thesis is aiming at handling such kind of data. READ MORE
