    • Assessment of Rheological Models for Run-out Distance Modeling of Sensitive Clay Slides, Focusing on Voellmy Rheology 

      Yifru, Ashenafi Lulseged (Master thesis, 2014)
      Sensitive clay landslides especially that of quick clay are the major natural hazards in Canada and Scandinavian countries. Fair estimation of post-failure movement (retrogression and run-out distances) is very important ...

    • Entrainment of Bed Sediments by Debris Flow 

      Sherchan, Bigyan (Master thesis, 2016)
      Debris flows have proved to be a major worldwide hazard for more than 100 years owing to the destruction of lives, property and infrastructures. This occurrence of debris flows is likely to increase in the future due to ...

    • Investigation of a screen structure for mitigating debris-flows along coastal roads 

      Yifru, Ashenafi Lulseged (Doctoral theses at NTNU;2020:249, Doctoral thesis, 2020)
      Debris-flow is one of the major natural hazards in Norway. The mountainous terrains of Norway are exposed to debris-flow hazards in relation to extreme weather events resulting in intense and prolonged rainfall. This hazard ...

    • Laboratory investigation of performance of a screen type debris-flow countermeasure 

      Yifru, Ashenafi Lulseged; Laache, Emilie; Norem, Harald Anders; Nordal, Steinar; Thakur, Vikas Kumar Singh (Journal article; Peer reviewed, 2018)
      Debris-flows are forms of landslides in mountainous regions that can potentially cause significant damage. Structural countermeasures to mitigate an entire debris-flow may become unrealistically massive and expensive. If ...

    • Preliminary study of debris flow impact force on a circular pillar 

      Yifru, Ashenafi Lulseged; Pradhan, Rosy N.; Nordal, Steinar; Thakur, Vikas Kumar Singh (Chapter, 2018)
      This paper presents results from a series of preliminary tests in a flume model, where impact forces on a circular pillar from debris flow is measured. The flume model is 0.3 m wide and 9 m long. It comprises of a run-out ...

    • Two-Phase Two-Layer Depth-Integrated SPH-FD Model: Application to Lahars and Debris Flows 

      Tayyebi, Saeid Moussavi; Pastor, Manuel; Hernandez, Andrei; Gao, Lingang; Stickle, Miguel Martin; Yifru, Ashenafi Lulseged; Thakur, Vikas Kumar Singh (Peer reviewed; Journal article, 2022)
      The complex nature of debris flows suggests that the pore-water pressure evolution and dewatering of a flowing mass caused by the high permeability of soil or terrain could play an essential role in the dynamics behavior ...
