ICIMOD Warns of Second Nepal-Tibet Flood Risk as Trishuli Blockages Threaten Landslide Dam

Summary

  • ICIMOD said debris from Wednesday’s flash flood may have temporarily blocked narrow sections of the Trishuli River, raising the risk of a second flooding event in Nepal and Tibet.
  • The danger is that any blockage could form a landslide dam, then fail and send another surge downstream.
  • Authorities and scientists are now assessing the size, location and stability of any potential river blockages to determine whether the threat is immediate.
  • The warning follows a major flash flood that already caused devastation on both sides of the Nepal-Tibet border.
