@Bachmann_h2 @hs_magdeburg Not a glacial collapse 👇 3.6K views · 24 likes · 1 reposts · 3 replies 31 Aug 2026 Well, this changes the story considerably. The initial headlines called this a “glacial collapse.” Satellite analysis now indicates the major failure was a massive bedrock collapse beneath the glacier. That distinction matters. This was fundamentally a geologic mass-failure htt 232.5K views · 3.4K likes · 1.1K reposts · 148 replies 31 Aug 2026 Granted, the underlying concept of risk analysis is to capture all possible events. But what was the actual probability of such scenarios? They could easily have been categorized as a 'residual' risk. However, climate change could cause the probability of these events to rise./9 5K views · 52 likes · 2 reposts · 2 replies 31 Aug 2026 Does this mean we must incorporate such events into flood risk management in the near future?

Best calibration achieved with a 100M m³ reservoir at impact zone, implying a bulking factor of 3.0 (30M m³ pure glacier water). Runtime on an NVIDIA RTX 5090: only 25 minutes for 120 mins real-time. /7 https://t.co/cW1qbaRMlD 5.7K views · 44 likes · 2 reposts · 2 replies 31 Aug 2026 It demonstrates that such events could, at least approximately, be modeled in advance. But in all honesty: who would use an initial volume of 100 million m³ as an initial condition in a flood risk analysis? /8 5.1K views · 64 likes · 5 reposts · 2 replies 31 Aug 2026 Tech Setup: The 2D hydrodynamic model solves Saint-Venant equations on a GPU (~1.37M 10x10m elements, 80 km river section). To account for heavy sediment/mud loads, we applied a very high roughness (Manning's n = 0.1) upstream. /6 https://t.co/FMeo050WM6 5.9K views · 51 likes · 3 reposts · 1 replies 31 Aug 2026 At 9:46 AM, the wave hit Trishuli (62 km away) at 30m depth and 41 km/h.The simulation visualizes the exact, narrow escape window where a heroic teacher evacuated his students just minutes before the school was completely wiped out. /5 https://t.co/1bGMtVutqT 6.4K views · 64 likes · 3 reposts · 1 replies 31 Aug 2026 Traveling further downstream: At 8:58 AM, the wave struck Syabrubesi (23 km from the impact zone).Water depths here still peaked at an astonishing 50 meters, with flow velocities reaching 12 m/s (43 km/h), causing total destruction. /4 https://t.co/K9ePdqrbC5 6.9K views · 54 likes · 3 reposts · 1 replies 31 Aug 2026 At 8:47 AM, the wave struck Timure (15 km away). Model depths exceeded 60m at 24 m/s (86 km/h). The inundation area matches reality: the entire village is wiped out, except for the red-roofed church on the upper edge. /3 https://t.co/JnNkuXtNW3 7.4K views · 60 likes · 4 reposts · 1 replies 31 Aug 2026 Impact: 8:37 AM. Just 7 mins later (8:44 AM), the wave hit the Rasuwagadhi border 13 km downstream. 🌊 Water depths: >70 METERS 🏃‍♂️ Flow velocity: 30 m/s (108 km/h) The model perfectly mirrors the actual BBC satellite destruction data (https://t.co/sZRrP3dhD3). /2 https://t.co 16.1K views · 75 likes · 6 reposts · 3 replies 31 Aug 2026 6 days ago, a glacier collapse triggered a catastrophic flash flood in Nepal/Tibet. Our FRM group at @hs_magdeburg did a 2D hydrodynamic hindcast via ProMaIDes. The modeled numbers are frightening. 👇 /1 #NepalFlood #Hydrology #Simulation https://t.co/sX9ZUPFBoh 97.1K views · 467 likes · 92 reposts · 18 replies 31 Aug 2026
