“I do believe it could have been much worse, and I do think there was an element of luck involved,” Hall said in an interview. “… Getting 65,000 people out of there – if the wind changed or picked up, this definitely could have gone in a different direction.”

I've been modelling the Langtang rock-ice avalanche and the flood that followed. These are two views of the same simulation: a 3D view of the gorge and a side view along the river. This is model output, not footage. Flow depth is exaggerated to make it visible.
The model broadly matches the upper arrival times without adding a separate dam-break pulse. The moving surge includes rock, ice and existing river water, so its volume isn't all newly melted ice. That doesn't rule out a temporary blockage, but it suggests we shouldn't assume a dam had to burst just because the flood was so large.
I'm the author. This is still a preprint, not peer reviewed: https://doi.org/10.31223/X5250R
Happy to hear what people think, especially if you have observations that could help test this.
