  1. 1. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

    Författare :Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

  3. 2. Hydrodynamic modelling of microbial water quality in drinking water sources

    Författare :Ekaterina Sokolova; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; faecal contamination; QMRA; faecal indicators; pathogens; risk assessment; microbial source tracking; Bacteroidales; E. coli;

    Sammanfattning : The faecal contamination of water sources can cause waterborne disease outbreaks among drinking water consumers. To design drinking water treatment and minimise consumer health risks, knowledge on source water quality is needed. 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. Hydrodynamic and Microbiological Modelling of Water Quality in Drinking Water Sources

    Författare :Ekaterina Sokolova; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECO Lab; Bacteroidales; inactivation; microcosm experiment; fate and transport modelling; pathogens; microbial source tracking; MIKE 3; faecal indicators;

    Sammanfattning : Faecal contamination of drinking water sources poses risks for waterborne disease outbreaks. To manage these risks the fate and transport of faecal contamination in a drinking water source need to be understood and quantitatively described. LÄS MER

  7. 5. METHODS FOR TRANSBOUNDARY WATER RESOURCES MANAGEMENT IN WATER STRESSED REGIONS – CASE STUDY: SOUTHERN AFRICA

    Författare :Dinis Juizo; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; river basin simulation; water quality monitoring; stakeholders involvement; Southern Africa; South Africa; Mozambique; transboundary water systems; Swaziland;

    Sammanfattning : Water resources management in water scarce regions like the Southern Africa Development Community (SADC) is challenging with both large hydro-climatic-induced scarcity and the considerable inter-annual fluctuations at the centre of the allocation problem. Water must be allocated both in time and space using acceptable criteria and most importantly, all stakeholders must adhere to the decisions imposed by water sharing agreements. LÄS MER
