    • Observations of the dynamic structure of snow avalanches 

      Nishimura, K.; Maeno, N.; Kristensen, Krister; Sandersen, Frode; Norem, Harald; Lied, Karstein (Journal article, 1993)
      During two winters, 1990–92, the dynamic structures of snow avalanches were studied in western Norway. Artificially released wet-snow avalanches ran down the avalanche chute and stopped in front of the retaining dam. Running ...

    • Snow avalanche dynamics : observations and experiments 

      Nishimura, K.; Ito, Y.; Keller, S.; McElwine, S.; Nohguchi, Y.; Izumi, K.; Kawada, K. (NGI Publication;203, Chapter, 1998)
      In order to investigate the dynamics and the detailed structure of snow avalanches, we have made systematic observations in the Shiai-dani, Kurobe Canyon since 1989. Velocities of the lower flowing component were calculated ...

    • Studies on the snow avalanche dynamics by the full-scale experiments 

      Nishimura, K.; Pérez-Guillén, Cristina; Ito, Yoichi; Yamaguchi, Satoru; Saito, Yoshihiko; Issler, Dieter; Fischer, Jan-Thomas (Lecture, 2018)
      Systematic full-scale but small avalanche experiments have been started since 2016 in Niseko, a ski resort in Hokkaido, Japan. Although the vertical drop in the test sites are 100 to 200 m, they have advantages that we are ...
