Flooding 24/7 is different than water when you need it

Huh. I hadn't thought about the airborne water as a sound suppression thing. That's super interesting. But I still don't quite see how that helps with the concrete.

If you can minimize the damage to the concrete then you don’t have to repair it as often.

...... right.....? And in what way does moving water do that better than always there water?

You’re spraying it around the rocket it’s not just sitting in a large puddle underneath. The goal is to be between the source of the sound/vibrations and the concrete.

Oh, I see what you're saying, you're saying the damage would be to the concrete around the periphery rather than immediately beneath the rocket. That makes sense, thanks!

I believe the issue is “Which is better: 1. A water deluge system which pours a huge amount of water between the rocket exhaust and the concrete pad. 2. A pool of water underneath the rocket exhaust.” I’m guessing a pool of water wouldn’t be as good because the rocket exhaust would blow hot water and steam everywhere in an uncontrolled manner.

A flat water surface might as well be concrete. It will reflect sound waves. The goal is to dampen the sound so you spray it through the air to disrupt the sound waves instead of reflect them.

I'd think it would just push the water out of the way right? Like if you have a puddle and you turn a leaf blower on it you'll blow the water away to expose the ground underneath. I'm thinking the same thing would happen in this case.
