Water levels reportedly rose by about nine metres in 30 minutes at Galchchi and seven metres at Malekhu. Because the Trishuli River enters the country as the Gandak, the event also has implications for India. Thakkar said monitoring should therefore cover the entire Bhote Koshi-Trishuli-Gandak corridor. Because temporary blockages can collapse within minutes or hours, rapid data sharing among China, Nepal and India is essential to provide timely warnings to downstream communities.
Thakkar said both events involved more than heavy rainfall, with unstable ice, rocks, steep slopes and sudden water release combining to create highly destructive floods. “This was not simply a flood generated by excessive rainfall,” Thakkar said, adding that the rapid rise in water levels pointed to an exceptionally energetic flood wave. Such a sharp increase, he said, could not be explained by a gradually developing monsoon flood. He said it would be misleading to describe the disaster simply as a cloudburst. Glacier retreat, thinning ice, melting permafrost, expanding glacial lakes and unstable slopes are reshaping hazard patterns across the Himalayas, Thakkar said.
the available evidence suggests the immediate trigger was a geomorphic and cryospheric process While rainfall and saturated slopes may have contributed to instability. it is increasing the underlying risk While climate change cannot automatically be identified as the direct cause of this flood. He recommended real-time monitoring using river gauges, cameras, satellites, weather radar and seismic sensors.
