  1. 1. Geosystem services to support decisions on subsurface use

    Författare :Emrik Lundin Frisk; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geosystem services; Sustainability; Subsurface; Conflict of interests; Ecosystem services;

    Sammanfattning : Awareness of the subsurface is in general low and is not a daily concern for decision-makers. This often results in that decisions on access to subsurface resources instead are guided by a ‘first come, first served principle’. LÄS MER

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

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

    Sammanfattning : 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. 3. Elastohydrodynamic lubrication : interferometric measurements, lubricant rheology and subsurface stresses

    Författare :Erik Höglund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : .... LÄS MER

  5. 4. Geophysical methods for the investigation of subsurface flows

    Författare :Andrew Patrick Bérubé; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Sammanfattning : Geophysical methods of investigating the substratum have been proven to provide quality data for a variety of applications. Despite this fact, such methods are not used in some fields to the degree that they could be. LÄS MER

  7. 5. Subsurface Environmental Impact in Urban Areas. Shallow Groundwater Composition, Corrosion of Soil-Buried Constructions, and Leachates from Reclaimed Asphalt Pavement

    Författare :Malin Norin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GC MS screening; soil-buried constructions; subsurface urban environment; shallow groundwater quality; corrosion; reclaimed asphalt pavement;

    Sammanfattning : Worldwide, groundwater represents the largest and most important source of potable water. Usually, urbanisation affects shallow urban aquifers in two ways: by radically changing patterns and rates of aquifer recharge, and by adversely affecting the quality of groundwater. LÄS MER
