Can we now stop saying that once suspended sediment returns to pre-event levels, then the system response is over? Great paper here with relevance to cascading hazards and landscape evolution.

On 21 July 2025, an extremely large rock avalanche occurred in the mountains in Wanrong Township in Hualien County, Taiwan. Initial measurements suggest that this ran out for about 6 kilometres.

I’d add NSF to that list. There is still some basic research needed on flash flooding hydrology and mechanics (eg rheology of the debris fronts) and that is needed to improve forecasts.
It'll take a dispassionate apolitical inquiry to learn what went wrong + why. Forecasts? Warnings? Staffing? That'll take time.
But, even today the president could make a national commitment to ensure it never happens again. To invest in instead of slashing NOAA, USGS, NRCS, and FEMA.
