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.
