Yesterday a reporter referred to the cause of the tragic deaths in the Guadalupe River flood in Texas as an "act of God".
Is it?
"an act of God is an extraordinary interruption by a natural cause (such as a flood or earthquake) of the usual course of events that experience, prescience, or care cannot reasonably foresee or prevent."
Did God cause the flood? or were the deaths caused by the actions or inaction of human beings?
The facts are:
- Global climate change affects local weather. https://climate.nasa.gov/
- The US Army Corps of Engineers Hydraulic Engineering Center developed its River Analysis System (HEC-RAS) computer modelling program in 1964. It was released to the public in 1995. Flood limits can be determined for any location. All that is needed are topographic and soils maps and a rainfall rate. https://en.wikipedia.org/wiki/HEC-RAS
- it's widely known that the Guadalupe River floods the area where the camps are located. Warning sirens were discussed. Nothing was done.
- If the Guadalupe River is modeled using the HEC-RAS program with the actual rainfall rate that occurred during the storm, then it would show flood depths and spread that match the actual depths and spread that occurred during the storm.
- There was no warning system other than "word of mouth", which is useless in a situation like the Kerrville flood. An effective alert system would have saved lives.
So, it appears that the tragedy in Kerrville TX was created by the actions and/or inaction of human beings. It's a wake-up call for everyone.
My recommendations: - instead of using 100-year or 500-year rainfall rates, use rainfall rates that are equal to the maximum recorded rainfall event--plus 10%. It's been reported that the rainfall rate that caused the flooding in Kerrville was 12 inches per hour. Adding 10% results in a rainfall rate of 13.2 inches per hour.
- keep an eye on the effects of global climate change on local weather. Intense storms with larger rainfall rates are occurring more frequently.
- update the rainfall rate if the existing recorded maximum rainfall rate is exceeded. HEC-RAS will generate new flood depths and spreads.
- don't build or rebuild in a flood plain.
- post signs, install sirens and use early warning systems to advise people of danger in floodplains.
And, don't blame God for disasters that human actions or inaction cause.

Kerrville, Texas will forever be known for the Guadalupe River flood that killed hundreds on July 4, 2025. People from everywhere will come to Kerrville, Texas to see for themselves where the tragedy and recovery took place.
Suitable monuments and/or a museum should be built that tell the stories of those who died during the flood and the stories of their families. They should honor those volunteers who came from everywhere to help the people of Kerrville recover from the devastation.
The story of the Kerrville flood should include a chapter on the mistakes that were made by government officials during and before the July 4 flood. Part of the legacy of the Kerrville flood is that those mistakes should never again be repeated anywhere in the USA.
