  1. 1. In the Pipe or End of Pipe? : Transport and Dispersion of Water-borne Pollutants and Feasibility of Abatement Measures

    Author : Christoffer Carstens; Vladimir Cvetkovic; Auli Niemi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contaminant transport modelling; Groundwater; Dispersion; Wave power; Eutrophication;

    Abstract : Eutrophication is one of the key environmental problems of today, both in terms of complexity and magnitude. For the Baltic Sea (BS), eutrophication is an acute problem, leading to hypoxic conditions at the bottom; a situation that is sustained and amplified, when phosphorus is released from hypoxic sediments.

  2. 2. Evaluation of Modern Irrigation Techniques with Brackish Water

    Author : Tarek Selim Aboulila; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Soil water; Soil Salinity; Drip irrigation; HYDRUS-2D 3D; El-Salam Canal; Egypt.;

    Abstract : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. READ MORE

  3. 3. Energy Efficient Eradication of Legionella in Hot Water Systems

    Author : Lobna Altorkmany; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Disease related to unsafe water, poor sanitation, and lack of hygiene is some of the most common causes of illness and death all around the world. Since the first detection of Legionella in Philadelphia 1976, Legionella is recognized to cause Legionellosis which is associated with two distinct forms: Legionnaires’ disease and Pontiac fever.

  4. 4. Hydrological modelling of green urban drainage systems : Advancing the understanding and management of uncertainties in data, model structure and objective functions

    Author : Ico Broekhuizen; Maria Viklander; Günther Leonhardt; Jörg Rieckermann; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Abstract : The use of green urban drainage systems such as green roofs, swales and pervious areas has in recent years become a popular option to reduce flood risk and water quality problems in a more sustainable way than with traditional pipe-based drainage systems. Computer models are valuable tools for the management of such systems. READ MORE

  5. 5. Improved environmental assessment in the development of wood-based products: Capturing impacts of forestry and uncertainties of future product systems

    Author : Gustav A Sandin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; wood; water use; scenario modelling; land use; impact assessment; product development; environmental assessment; end-of-life modelling; sustainability assessment; forestry;

    Abstract : The prospect of reducing environmental impacts is a key driver for the development of new wood-based products. But as wood-based products are not necessarily environmentally superior to non-wood alternatives, there is a need to assess the environmental impact of the product and guide the development process.
