ELI5- How does only 17″ of rain cause multiple feet of floodwater?

65 viewsOtherPlanetary Science

My little girl is 7 and just isn’t wrapping her head around this and I need to find a better way to explain this.

She is so so smart because she saw the coverage of Helene, and heard 17″ and hot confused.

I told her the water runs from the high places to the low places, but then she asked why the water doesn’t leave the low places and why is it still flooded.

I’m bad at dumbing things down.

Maybe make the comparison that 17″ of water filling a volume of a small area like a square foot isn’t much water overall, but if you took the water from an area of say 1,000 miles filled up to a volume of 17″ it is an enormous amount of water.
