    • Analysis of the measured pore pressure and hydraulic data from Roskrepp hydropower plant 

      Ghimire, Sanyam (Master thesis, 2023)
      There is change in operational regime of hydropower power plants in Norway after deregulation of energy markets and recent integration of renewable and unregulated energy sources such as wind and solar in an energy mix. ...

    • Development of in-situ rock stress map of south-western part of Norway 

      Ghimire, Sanyam; Panthi, Krishna Kanta (Chapter, 2024)
      Knowledge of in-situ rock stress is important for underground projects like mining, nuclear repository, hydropower and other utility tunnels and caverns for the assessment of stability condition. Specifically, it is very ...

    • Hydraulic Transient Impact on Surrounding Rock Mass of Unlined Pressure Tunnels 

      Ghimire, Sanyam; Panthi, Krishna Kanta; Vereide, Kaspar Vatland (Peer reviewed; Journal article, 2023)
      The frequent pressure pulsations due to hydraulic transients in hydropower plants induce cyclic loading on the rock mass that may contribute to increased instances of block falls and increased risk of tunnel collapse over ...

    • Suspended Sediment Source and Transport Mechanisms in a Himalayan River 

      Ghimire, Sanyam; Singh, Umesh; Panthi, Krishna Kanta; Bhattarai, Pawan Kumar (Journal article; Peer reviewed, 2024)
      The process of estimating sediment load has been a daunting issue in hydraulics and the water resource field. Several methods exist for predicting the sediment load in a catchment or river, but the majority of these methods ...
