    • A pore-scale model for permeable biofilm: Numerical simulations and laboratory experiments 

      Landa-Marban, David; Liu, Na; Pop, Iuliu Sorin; Kumar, Kundan; Pettersson, Per; Bødtker, Gunhild; Skauge, Tormod; Radu, Florin Adrian (Peer reviewed; Journal article, 2018)
      In this paper, we derive a pore-scale model for permeable biofilm formation in a two-dimensional pore. The pore is divided into two phases: water and biofilm. The biofilm is assumed to consist of four components: water, ...

    • An Upscaled Model for Permeable Biofilm in a Thin Channel and Tube 

      Marban, David Landa; Bødtker, Gunhild; Kumar, Kundan; Pop, Iuliu Sorin; Radu, Adrian Florin (Peer reviewed; Journal article, 2020)
      In this paper, we derive upscaled equations for modeling biofilm growth in porous media. The resulting macroscale mathematical models consider permeable multi-species biofilm including water flow, transport, detachment and ...

    • Hvordan plast og rydding av plast påvirker økosystemet på Lisle Lyngøy (Hovedrapport) 

      Bødtker, Gunhild; Haave, Marte; Velle, Gaute; Andersen, Gidske L.; Gomiero, Alessio; Gaasøy, Rune; Bruvik, Kenneth; Bastesen, Eivind (Research report, 2023)
      Marin plastforurensing har på Lisle Lyngøy ført til landskapsendring som har fått direkte konsekvenser for øyens hydrologi. Landskapsendringen er forårsaket av en unormalt rask volumøkning av driftvollen som ligger ved den ...

    • Microfluidic study of effects of flow velocity and nutrient concentration on biofilm accumulation and adhesive strength in the flowing and no-flowing microchannels 

      Liu, Na; Skauge, Tormod; Landa-Marbán, David; Hovland, Beate; Thorbjørnsen, Bente; Radu, Florin Adrian; Vik, Bartek Florczyk; Baumann, Thomas; Bødtker, Gunhild (Peer reviewed; Journal article, 2019)
      Biofilm accumulation in porous media can cause pore plugging and change many of the physical properties of porous media. Engineering bioplugging may have significant applications for many industrial processes, while improved ...

    • Rapid landscape changes in plastic bays along the Norwegian coastline 

      Bastesen, Eivind; Haave, Marte; Andersen, Gidske Leknæs; Velle, Gaute; Bødtker, Gunhild; Krafft, Charlotte Gannefors (Peer reviewed; Journal article, 2021)
      The Norwegian Coastal Current transports natural debris and plastic waste along the Norwegian coastline. Deposition occurs in so-called wreck-bays and includes floating debris, such as seaweed, driftwood and volcanic pumice, ...
