Look above the river
Summary
The Budhi Gandaki and Rasuwa floods highlight how upstream landslides, ice avalanches and blocked streams can trigger major disasters far downstream. The article calls for better hazard assessment, early warning systems and reconstruction planning that looks beyond the immediate riverbanks.
Key Points
- Preliminary reports say a landslide near Siringe Himal blocked a stream before the Budhi Gandaki flood, while the Rasuwa event began with a rock-ice avalanche near Langtang Lirung.
- The floods show that river disasters can start far above the banks and require monitoring of slopes, tributaries and upstream blockage risks.
- The article argues for better evacuation planning, local warning systems and cross-border communication before disasters occur.
- It also says reconstruction should not simply replace damaged infrastructure in the same place without reviewing upstream exposure and climate-related risks.
