  1. 1. Beneficial Use of Stormwater - Opportunities for urban renewal and water conservation

    Detta är en avhandling från Department of Water Resources Engineering, Lund Institute of Technology, Lund University

    Författare :Edgar Villarreal-Gonzalez; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; offshore technology; hydraulic engineering; Civil engineering; water conservation; rainwater collection; Best Management Practices; Urban stormwater; green-roofs; open drainage systems;

    Sammanfattning : This thesis investigates the beneficial use of stormwater in Swedish urban environments. The focus has been on open stormwater systems for source control, as well as rainwater collection systems. To analyse the implementation of open stormwater systems, two case studies are presented: Augustenborg in Malmö and Bäckaslöv wetland in Växjö. LÄS MER

  2. 2. Urine separating wastewater systems experiences of design and nitrogen conservation

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Erica Johansson; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Urine separating (US) wastewater systems, where urine is collected and used as a fertiliser, may be a strategy to achieve a high degree of nutrient recycling from human waste to agriculture. The Swedish experiences of US systems show that the design of the toilets and the sewers are of great importance to achieve a working system. LÄS MER

  3. 3. Electropermutation assisted by ion-exchange textile removal of nitrate from drinking water

    Detta är en avhandling från Stockholm : KTH

    Författare :Carl-Ola Danielsson; Anders Dahlkild; Mårten Behm; Anna Velin; Gerald Pourcelly; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion-exchange textile; Ion-exchange membrane; Electropermutation; Electroextraction; Electrodialysis; Electrodeionisation; Modeling; Conducting spacer; Nitrate removal; Water treatment; Water dissociation; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Sammanfattning : Increased levels of nitrate in ground water have made many wells unsuitable as sources for drinking water. In this thesis an ion-exchang eassisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. LÄS MER

  4. 4. Influence of fractures and air bubbles on the pressure distribution embankment dams

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Mats Billstein; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : In some large embankment dams unexpected pore pressure distributions within the core have been observed. As an example, the piezometer pressures in WAC Bennett Dam, Canada, which rose for about four years after the reservoir was filled, were steady for two years and subsequently declined. LÄS MER

  5. 5. Atlantic Water in the Nordic Seas A satellite altimetry perspective on ocean circulation

    Detta är en avhandling från Stockholm : Department of Meteorology, Stockholm University

    Författare :Sara Broomé; Johan Nilsson; Jonas Nycander; Léon Chafik; Michael A. Spall; [2020]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arctic Ocean climate; ocean heat transport; sea surface height; topographic control; Lagrangian trajectories; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : The Atlantic Water in the Nordic Seas contributes to the mild climate of Northern Europe and is the main oceanic source of heat for the Arctic. The northward bound transport of the warm and saline Atlantic Water is mediated by a topographically constrained cyclonic boundary current along the Norwegian continental slope. LÄS MER
