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

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

    Abstract : 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. READ MORE

  4. 2. Underneath Norrköping : An Urban Mine of Hibernating Infrastructure

    Author : Björn Wallsten; Joakim Krook; Vanesa Castán Broto; Linköpings universitet; []
    Keywords : Urban mining; infrastructure; hibernating stocks; Material Flow Analysis; infrastructure studies; Norrköping;

    Abstract : This study examines the subsurface infrastructure in the Swedish city of Norrköping from an urban mining perspective. Urban mining is a broadly defined term for different strategies that regard the built environment as a resource base for materials. READ MORE

  5. 3. The Urk World : Hibernating Infrastructures and the Quest for Urban Mining

    Author : Björn Wallsten; Joakim Krook; Stefan Anderberg; Vasilis Galis; Simon Marvin; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban mining; infrastructure; material flow analysis; hibernating stocks; copper;

    Abstract : This PhD thesis concerns urban mining, an umbrella term for different recycling strategies aimed to recover materials from the built environment. More specifically, it focuses on hibernating urban infrastructures, that is: cables and pipes that have been left behind in their subsurface location after they were disconnected. READ MORE

  6. 4. Development of RMT techniques for urban infrastructure planning : Stockholm Bypass (Förbifart) case study

    Author : Suman Mehta; Alireza Malehmir; Mehrdad Bastani; Laust Pedersen; Andreas Pfaffhuber; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The tensor radio-magnetotelluric (RMT) method has extensively been used in near-surface investigations to obtain resistivity models of the subsurface. The main objective of this thesis is to further develop the RMT survey technique for a less paid attention and challenging environment namely on shallow water bodies and in the urban environment.

  7. 5. Microbial degradation of wooden foundation piles in urban context – causes and concerns

    Author : Johanna Elam; Göteborgs universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Modern infrastructural projects can endanger historical piled foundations supporting cultural heritage buildings, as groundwork can affect the subsurface environment by lowering the local groundwater level and increasing oxygenation in the soil. Wooden foundation piles are thereby placed at risk, as the durability of buried wood material is dependent on a stable, waterlogged, and anoxic environment. READ MORE
