AbstractThis study analyzed debris flow disasters in Siou-lin Township in Hualien County during typhoon Soula and summarized factors which triggered debris flow non-rectilinear motion. To clarify the existence of similar
susceptibility at other torrents, continuous debris flow scenario simulations were given to five debris flow torrents in Kao-Ping river basin. The simulation results showed part of the debris flow torrents had the susceptibility of being non-rectilinear accumulation, and some of torrents had the same accumulation areas. Qualitative analysis showed this phenomenon occurs with differences in debris slide potential, gradient difference, and gully terrain inside the upstream
sub-catchments. Finally, some recommendations were provided for the current hazard susceptibility analysis
methods.
