  2. 16. Hydrogeological Methods in Geotechnical Engineering: Applied to settlements caused by underground construction

    Author : Jenny Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; excavation; tunnel; hydrogeology; consolidation; pumping test; Groundwater; inflow rate; settlement; transmissivity; pore pressure; clay;

    Abstract : Improvement in the infrastructure in urban areas generally involves underground construction with tunneling and deep excavations. One important consideration when constructing in cities founded on soft soil is settlement resulting from groundwater drawdown. The potential cost of excessive settlement in these projects is immense. READ MORE

  4. 17. Conceptualization of solute transport using time domain reflectometry. A combined laboratory and field study

    Author : Magnus Persson; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeologi; geographical and geological engineering; Hydrogeology; electrical conductivity; Solute transport; unsaturated zone; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : Solute transport in the unsaturated zone is a complex process. The first of the two objectives for this study was to examine how it could be conceptualized under different flow conditions. READ MORE

  5. 18. Hydrogeochemistry and spatial variability of arsenic and other trace elements in the Lower Katari Basin around Lake Titicaca, Bolivian Altiplano. : Impact on drinking water quality and groundwater management

    Author : Israel Quino Lima; Prosun Bhattacharya; Jerker Jarsjö; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arsenic; trace elements; multivariate analysis; spatial variability; hydrogeology; spatio-temporal variability; Lower Katari Basin; Bolivian Altiplano; alluvial sediments; Arsenik; spårelement; multivariat analys; rumslig variabilitet; hydrogeologi; spatio-temporär variation; Nedre Katari-bassängen; Bolivian Altiplano; alluviala sediment; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Arsenic (As) contamination in drinking water is a world-wide problem. Thenatural origin of As, its mobility and transport are of great interest in BolivianAltiplano (Lower Katari Basin: LKB and Sothern Poopó Basin: SPB) due topresence of mineral ore deposits, brines, hot springs and volcanic rocks.

  6. 19. Surface Wave Testing of Pavements

    Author : Nils Rydén; Teknisk geologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Hydrogeology; inversion; guided waves; road; pavement; Surface waves; non-destructive testing;

    Abstract : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. READ MORE

  7. 20. Urban Snowmelt Processes: Modelling and Observation

    Author : Annette Semadeni Davies; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; energy; runoff; snow properties; heterogeneity; hydrological modelling; Urbanisation; snowmelt; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : In northern Scandinavia and other cold regions, urban drainage systems are often unable to cope with the high volumes of melt water which can be sustained for several weeks. High waste water treatment plant inflows, combined system overflows and low water quality are a few problems associated with snowmelt. READ MORE
