Understanding the combination of meteorological, geomorphological and hydrological factors that led to the Texas flood could help prevent future disasters.

Over 130 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

With more rain on the way, the risk of life-threatening flooding was still high in central Texas on Monday even as crews search urgently for the missing following a holiday weekend deluge that killed at least 82 people, including children at summer camps. Officials said the death toll was sure to rise.
