Nepal faces secondary flash flood threat as debris forms dam: ICIMOD cryosphere specialist

Nepal faces secondary flash flood risks as debris forms a temporary dam. Over 470 people have died and nearly 1,000 are missing from recent floods. Researchers are investigating an ice-rock avalanche as the initial disaster cause. A similar event in Chamoli, India, saw a gradual lake breach without a major flood. Nepal has issued a new flood warning after water levels rose at the affected site.
