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

91 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.

Try explaining “storm surge” to her. Show her in the bathtub that you can push water and make its level go higher. Then explain that the water being pushed by the wind keeps the water draining from higher elevations from escaping to the sea.

It’s cool that she wants to learn this, and that you are trying to help her understand.
