This not a flash flood but a mud flow similar to a Lamar.
Density of the Flow is similar to concrete at it Carries massive boulder as big as several storeys buildings and erodes the valley base triggering landslides. This is how deep valleys are dug in high mountains areas.

🚨🌊 Catastrophic flooding in Nepal yet again.

A flash flood on the Budhi Gandaki early this morning swept away about 35 to 40 homes in Gorkha, and a local official says around 150 more were flooded downstream at Arughat. Six bridges are gone, 10 people are missing, and army helicopters have airlifted villagers out.

The wave is literally bigger than the entire frame.

Nazaré from a jet ski looks like an absolute death wish.

#Nepal C’est terrible à dire mais c’est par ce type de coulée que sont creusées les vallées en montagne, partout dans le monde. Notre occupation du territoire ne peut s’y adapter. Au mieux l’alerte précoce et l’évacuation peut sauver les habitants.
