  2. 1. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas

    Author : Jonas Sundell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; urban hydrogeology; pore pressure reduction; subsidence; geostatistics; groundwater leakage; soft soil; groundwater drawdown; spatial variability; settlement; probabilistic; risk assessment;

    Abstract : Groundwater drawdown induced ground subsidence is a severe problem in many regions around the world. Leakage of groundwater into a sub-surface construction, resulting in drawdown and subsequent subsidence, can lead to immense damage costs on buildings and installations in urban areas. READ MORE

  4. 2. Value of Information Analysis in Rock Engineering Investigations

    Author : Miriam Zetterlund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Observational Method; Rock mass characterisation; Value of Information;

    Abstract : A challenge in rock engineering is to strike a balance between a reasonable level of investigation and uncertainty in the geological conditions. Value of Information Analysis (VOIA) provides support for decisions about investigation strategies. READ MORE

  5. 3. Geosystem services to support decisions on subsurface use

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

    Abstract : 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’. READ MORE

  6. 4. The Impact of Fracture Geometry on the Hydromechanical Behaviour of Crystalline Rock

    Author : Johan Thörn; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Laboratory experiments; Fracture aperture; In situ experiments; Conceptual model; Äspö HRL; Fracture geometry; Stereo photogrammetry; Hydromechanical coupling; Fracture normal stiffness;

    Abstract : Effective construction of tunnels in fractured crystalline rock requires a unified approach for handling rock mechanics and hydrogeological issues. Traditionally, rock mechanics and hydrogeology not only use different nomenclature, they also measure parameters such as e.g. aperture differently. READ MORE

  7. 5. Arsenic in Alluvial Aquifers in the Meghna Basin, Southeastern Bangladesh : Hydrogeological and Geochemical Characterisation

    Author : Md. Aziz Hasan; Prosun Bhattacharya; William Burgess; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alluvial aquifer; groundwater; arsenic mobilisation; geology; Meghna basin; Bangladesh; Water engineering; Vattenteknik;

    Abstract :  Elevated levels of arsenic (As) in Bangladesh groundwater has emerged as a massive calamity exposing a large population to the risk of As toxicity from drinking water sources and agricultural products. Holocene alluvial aquifers in the delta- and flood-plains of the Ganges-Brahmaputra- Meghna (GBM) river systems are severely affected by high levels of As in groundwater. READ MORE
