Expert calls Nepal floods a regional 'wake-up call' for dam safety and monitoring
An expert in critical geography says the devastating flash floods and mudslides in the Nepal-China border region should be a 'wake-up call' for countries building large dams in high mountains. The death toll from the Aug 26 disaster has risen to 1,130, with nearly 4,500 people still missing. The expert warns that dams can amplify damage from such glacial events.
