  • Flash floods struck Nepal’s Budhi Gandaki River in Gorkha district, damaging infrastructure.
  • Flash floods are sudden, rapid floods that develop within minutes or hours due to intense rainfall, cloudbursts, sudden release of water or the bursting of temporary river blockages.
  • They carry large amounts of water, mud, rocks and debris, causing sudden destruction and loss of life.
  • In Gorkha district, Nepal, a landslide above Siuribas reportedly blocked the Chumke Khola stream, triggering a sudden release of floodwater downstream.
  • In the Himalayas, retreating glaciers, unstable slopes, glacial lake outbursts and loose sediments can increase flash-flood risks.
