EDITORIAL: Lower blasting risk with proven hydrological engineering
Summary
Nepal is preparing technical measures to lower water levels in high-risk glacial lakes to reduce the danger of catastrophic GLOFs. The piece warns that controlled blasting could be unsafe and argues for proven hydrological engineering methods instead.
Key Points
- The government is planning technical interventions to reduce water levels in extremely high-risk glacial lakes to prevent Glacial Lake Outburst Floods (GLOFs).
- The article warns that blasting in fragile moraine environments could destabilize slopes and worsen downstream damage.
- It cites successful non-invasive drainage work at Imja Tsho and Tsho Rolpa as safer alternatives.
- The author urges hydrological engineering, subsurface surveying, and early-warning systems instead of explosive methods.
