Landslide may have triggered flash flooding in Budhi Gandaki, officials say

The Department of Hydrology and Meteorology said the Trishuli river corridor remained at very high flood risk. Water levels were above the danger threshold and continued to rise and fall. Authorities warned communities around Mugling and farther downstream in Chitwan and Nawalparasi to stay alert.

The cause has not been confirmed. Residents suggested an avalanche on Mount Shringi, but officials said that idea remained unconfirmed. Parajuli reported a landslide near the mountain and stressed that all explanations were still preliminary. Further examination of satellite images and river conditions is therefore important.

The exact sequence has not been confirmed. The Flood Forecasting Section was still examining satellite images, and officials said the explanations remained preliminary. Meanwhile, river flow continued to fluctuate, with the Trishuli corridor at very high risk. Communities downstream were urged to remain alert.

The article does not identify every settlement at risk or give a precise distance in kilometres. It does make clear that the potential danger reaches from the Trishuli corridor near Benighat toward communities around Mugling, Chitwan, and Nawalparasi. Residents were told to remain alert while flows changed.

Authorities urged people around Mugling and farther downstream in Chitwan and Nawalparasi to remain alert. The warning shows that risk can extend beyond the suspected blockage. People near the river may need to follow official instructions quickly while officials continue assessing the cause and monitoring water levels.

The Flood Forecasting Section reported that the river’s flow continued to fluctuate. Water levels remained above the danger threshold, and the Trishuli corridor as far as Benighat stayed at very high risk. This uncertainty explains why authorities warned downstream communities to remain alert.

Residents suggested an avalanche may have occurred on Mount Shringi, but that suggestion was unconfirmed. Hydrologist Binod Parajuli said a landslide occurred near the mountain and that all explanations remained preliminary. Officials were examining satellite images while monitoring changing river levels and flood risk.
