    • Weight of evidence tools in the prediction of acute fish toxicity 

      Belanger, Scott E.; Lillicrap, Adam David; Moe, S. Jannicke; Wolf, Raoul; Connors, Kristin; Embry, Michelle R. (Peer reviewed; Journal article, 2022)
      Acute fish toxicity (AFT) is a key endpoint in nearly all regulatory implementations of environmental hazard assessments of chemicals globally. Although it is an early tier assay, the AFT assay is complex and uses many ...

    • Wetting-Drying Response of an Unsaturated Pyroclastic Soil Vegetated with Long-Root Grass 

      Capobianco, Vittoria; Cascini, Leonardo; Cuomo, Sabatino; Foresta, Vito (Peer reviewed; Journal article, 2020)
      This paper investigates the effect of a long-root grass on the hydraulic response of a partially saturated pyroclastic soil. The work is based on both long-term monitoring under atmospheric conditions and short-term ...

    • Wetting-induced collapse behaviour of a natural and vegetated coarse pyroclastic soil 

      Capobianco, Vittoria; Cascini, Laonardo; Cuomo, Sabatino; Foresta, Vito (Peer reviewed; Journal article, 2020)
      Unsaturated pyroclastic soils originated by Vesuvius volcano show a collapsible behaviour upon wetting with a significant reduction in volume and rearrangement of solid skeleton. The paper investigates the role played by ...

    • Wind-tunnel study of snowdrift around avalanche defence structures 

      Jaedicke, Christian; Naaim-Bouvet, Florence; Granig, Matthias (Journal article, 2004)
      Avalanche defence structures such as retarding dams and breaking mounds are widely used to protect residential areas and other kinds of infrastructure. The effect of the defence structures depends largely on their effective ...

    • Yield Stresses in Soft Contracting Clays 

      Aas, Gunnar; Lacasse, Suzanne (NGI Publication;209, Chapter, 2022)
      The undrained shear strength su along an arbitrary failure plane can be expressed as: su = 1/2(σ'ULS − σ'LLS) (1) where σ'ULS and σ'LLS denote the upper (U) and lower (L) effective, normal, compressive failure stresses ...

    • Økt skredfare kan avverges 

      Jaedicke, Christian; Isaksen, Ketil; Sletten, Kari; Kronholm, Kalle (Klima;1-2009, Chapter, 2009)
      Klimaendringer gir villere vær, mer nedbør og flere skredhendelser i deler av Norge. Men dette trenger ikke føre til flere dødsfall og økte materielle skader, hvis vi bruker sunn fornuft og følger bygningsloven.

    • Øysand research site: Geotechnical characterisation of deltaic sandy-silty soils 

      Quinteros, Santiago; Gundersen, Aleksander Sæthereng; L Heureux, Jean-Sebastien; Carraro, J. Antonio H.; Jardine, Richard (Journal article; Peer reviewed, 2019)
      This paper describes the geology and geotechnical engineering properties of the fluvial and deltaic gravelly-sandy-silty sediments at Øysand, Norway. Geophysical and geotechnical site investigations carried out between ...
