1. 1. Groundwater-Seawater Interactions : Seawater Intrusion, Submarine Groundwater Discharge and Temporal Variability and Randomness Effects

   Författare :Carmen Prieto; Georgia Destouni; Vassilios Kaleris; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; Seawater intrusion; submarine groundwater discharge; coastal groundwater management; coastal zone management; temporal variability; temporal randomness; Vattenteknik; Water engineering; Vattenteknik;

   Sammanfattning : Fresh groundwater quality and availability in coastal areas is affected by seawater intrusion into coastal aquifers, and coastal water quality and ecosystem status may be significantly affected by groundwater pollutants that are transported into coastal waters by submarine groundwater dis-charge (SGD). This thesis uses an overall regional perspective for investigating: i) seawater intru-sion and its possible control in sustainable coastal groundwater management; ii) SGD and its relevant quantification as one interacting part among the diverse main regional pathways of freshwater and tracer/pollutant inputs from land to sea; and iii) the integrated system functioning of both i) and ii) as main components of the same coastal groundwater system.

3. 2. Simulation and Optimization of Recirculating Aquaculture Systems

   Författare :Simon Pedersen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic modelling; optimization; biofilter; wastewater treatment; Recirculating aquaculture;

   Sammanfattning : Recirculating aquaculture -- intensive fish farming with water treatment and reuse -- has great potential as a method for sustainable food production. Benefits over traditional aquaculture include opportunities to reduce nitrogen emissions to water, control of temperature, salinity and pH, reduced environmental impact of escapes and better protection against e.

4. 3. Risk Assessment and Decision Support for Managing Drinking Water Systems

   Författare :Andreas Lindhe; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drinking water; risk assessment; decision analysis; water safety plan; water supply; multi-criteria decision analysis; dynamic fault tree analysis;

   Sammanfattning : The vital importance of a reliable and safe drinking water supply makes efficient risk management necessary for water utilities. Risks must be assessed and possible risk-reduction measures evaluated to provide relevant decision support. LÄS MER

5. 4. Integrated and Probabilistic Risk Analysis of Drinking Water Systems

   Författare :Andreas Lindhe; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water safety plan; customer minutes lost; probabilistic; fault tree analysis; risk analysis; risk; integrated; drinking water system; hazard; uncertainty;

   Sammanfattning : Drinking water supply is an essential public function but is at the same time exposed to risks. Since a totally risk-free society is not attainable, risks need to be managed efficiently to achieve an acceptable level of risk. LÄS MER

7. 5. Liquid landscapes: Human-water interactions and water scarcity in Yanque, Peru

   Författare :Malene Brandshaug; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; water scarcity; human-water interactions; Peru; water management; more-than-human; entanglements; coloniality; Anthropocene;

   Sammanfattning : In the farming district of Yanque in the Southern Peruvian Andes, everyday life revolves around acquiring enough water for irrigation. This thesis concerns water scarcity and focuses on a range of water management practices. LÄS MER
