Our transcription: Meandering rivers are associated with one of the world's most significant geological hazards: flooding.
Floods are absolutely a naturally part of the river's cycle, and, in fact, flooding, that is to say, over-bank discharge, is common enough that it shouldn't surprise anyone.
Geologists have looked at this pretty carefully over the last few years.
We have records which indicate that most streams overtop their banks about every two and a half years -- that's nothing unusual at all.
Anyone who is surprised by flooding are the ones who are not paying attention.
