  1. 1. Urban Water Security – Local Conditions and Regional Context : A case study of attitudes and water use behaviour in Windhoek, Namibia

    Författare :Therése Sjömander Magnusson; Jan Olof Lundqvist; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water supply; urban; water management; water demand management WDM ; vattenförsörjning; Namibia; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : The world is becoming urbanised. Between 1995 and 2025, it is estimated that the cities and towns of the developing world will have absorbed another two billion people. A majority of these people will be poor and settle down in the unregulated areas. LÄS MER

  3. 2. Microbial risk assessment and its implications for risk management in urban water systems

    Författare :Therese Westrell; Thor-Axel Stenström; Nick Ashbolt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. LÄS MER

  4. 3. Water powered percussive rock drilling : process analysis, modelling and numerical simulation

    Författare :Göran Tuomas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. LÄS MER

  5. 4. System for water driven down-hole hammer drilling

    Författare :Göran Tuomas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Drilling with water driven down-hole hammers is a recently developed method for competitive production of boreholes. The technology requires large flow rates of preferably high quality fluid to drive the hammer tool. One method to reduce the consumption is to process and recycle the used drilling fluid. LÄS MER

  7. 5. Effects of Watershed Dynamics on Water Reservoir Operation Planning : Considering the Dynamic Effects of Streamflow in Hydropower Operation

    Författare :Nicholas Zmijewski; Anders Wörman; Andrea Bottacin-Busolin; Francesca Pianosi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reservoir operation; dispersion processes; wave diffusion; multi-objective operation; water resource management; discharge variability; power spectrum analysis; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Water reservoirs are used to regulate river discharge for a variety of reasons, such as flood mitigation, water availability for irrigation, municipal consumption and power production purposes. Recent efforts to increase the amount of renewable power production have seen an increase in intermittent climate-variable power production due to wind and solar power production. LÄS MER
