  2. 1. Subsurface dams in water resource management : methods for assessment and location

    Author : Imran Ali Jamali; Bo Olofsson; Stephen Foster; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subsurface dams; Groundwater; GIS; Regolith thickness; Groundwater; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Natural groundwater storage can be improved by constructing a subsurface barrier that is a subsurface dam, in order to capture the subsurface flows and raise the groundwater levels (GWLs) in the sediment layers. Subsurface dams are preferable to surface dams because of lower evaporation, higher functionality, lower cost of construction, lessened risk for contamination and the possibility of utilizing land over the dam.

  4. 2. Radon in Groundwater- Influencing Factors and Prediction Methodology for a Swedish Environment

    Author : Kirlna Skeppström; Bo Olofsson; Per Erik Jansson; Jon Petter Gustafsson; Gerhard Barmen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon; Grondwater; GIS; RV method; Multivariate statistics; Water engineering; Vattenteknik;

    Abstract : This thesis presents a method for predicting radon (222Rn) levels in groundwater on a general scale, within an area of approximately 185 x 145 km2. The method applies to Swedish conditions, where 222Rn is the main contributor to natural radioactivity. READ MORE

  5. 3. Making water information relevant on local to global scale – the role of Information Systems for Integrated Water Management

    Author : Fredrik Hannerz; Georgia Destouni; Dennis Lettenmaier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Integrated water management; hydrology; environmental information systems; environmental monitoring; land cover; GIS; Sweden; Baltic Sea; European Union; global water; global change; Water Framework Directive; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Abstract : Relevant information is essential for finding solutions in Integrated Water Management (IWM). Complex water systems and a need for increasing integration of sectors, actors and scales in IWM require new methods for developing and managing such information. READ MORE

  6. 4. Water supply management in an urban utility : A prototype decision support framework

    Author : Frank Kizito; Roger Thunvik; Kalanithy Vairavamoorthy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decision support systems; Geographic information systems; Participatory planning; Urban water supply management; Decision support framework; Action research; Water engineering; Vattenteknik;

    Abstract : In this study, four real-life problem situations were used to explore the challenges of developing and implementing decision support tools for planning and management within an urban water utility. The study sought to explore how the degree of adoption of formal decision support tools in practice, generally perceived to be low, could be improved. READ MORE

  7. 5. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions

    Author : Alireza Nickman; Bo Olofsson; Per-Erik Jansson; Nils-Otto Kitterød; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; Flood; Moisture; Temperature; Groundwater; GIS; Uncertainity; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.
