As we continue to grieve the loss of so many Hill Country flood victims, there is a lot of information being thrown around. <\/p>\n
KSAT wants to remind people what a \u201c100-year flood\u201d actually means.<\/p>\n
Whatever the Weather<\/p>\n
A collection of daily blog posts from the KSAT Weather Authority.<\/p>\n
STATISTICAL, NOT LITERAL<\/p>\n
A 100-year flood is a flood event that has a 1% chance of occurring in any given year, not once every 100 years. It\u2019s calculated using past rainfall, streamflow and topography to estimate flood risk. <\/p>\n
That means there could be another catastrophic flood event next year, unfortunately. <\/p>\n
Just weeks before the Guadalupe River flooded, 13 people were killed in a flood on the Northeast Side of San Antonio, which is only 20 to 40 miles away. <\/p>\n
San Antonians live in Flash Flood Alley. Therefore, it\u2019s important to be prepared. <\/p>\n
100-YEAR FLOOD LEVEL CAN CHANGE<\/p>\n
The \u201c100-year flood level\u201d is not a fixed benchmark. As the climate warms, storms grow more intense and frequent. <\/p>\n
At the same time, land development, especially in floodplains, changes how water flows across the landscape. <\/p>\n
Paved surfaces prevent water from soaking into the ground, increasing runoff and raising the flood risk. In other words, <\/b>what was considered a 100-year flood a few decades ago might now be a 25-year event, or even more frequent.<\/p>\n
WHAT CAN WE DO<\/p>\n
We cannot prevent floods, but we can do everything we can to stay prepared.<\/p>\n
