Which risk increases significantly when alpine glacial streams experience intense, seasonal melt?

💡 Explanation

Increased runoff can overwhelm stream channel capacity and lead to flash flooding; peak flow timing is crucial because downstream areas have little time to prepare given rapid water transport, therefore earlier surges are dangerous rather than changes in any gradual riparian ecological or subsurface effects.
