They are related. Higher water levels equals higher flow rates if the velocity is constant. I would think flow rates are used because they are a more accurate measure of whats going on. 40 feet of stagnant water is bad, but it won't erode anything like 35 foot of water hauling arse.
ETA: That was an educated guess BTW. I'm no expert.
Doesn't flowing water have less outward pressure than stagnant water? Thus wouldnt stagnant water have more potential for structure failure? Please Advise......

Monterey was under a mandatory evac.? Have you heard this? I haven't read it anywhere.
My sister's in Monterey right now. She said they heard there will be one by Sunday, but not yet.

you have hydrostatic pressure which it water at a static state(not moving) if that water is moving you have the static pressure from the weight of the water and you have Hydrodynamic pressure.

Wife just told me a bunch of Vidalia folks are driving around Ntz looking for rental property.
Plenty of empty houses in Natchez from what I hear. This may be a blessing in disguise if realtors can work it out with sellers.
Hope it doesn't come to that though.
I know of several Vidalia residents making plans to move in with family in Natchez until threat is over.

Well how bout if 2 days out from Katrina the weather guy said, "If those levees break in Nola, things could get interesting." See how it comes across?

Yes it would. You just have to follow it up with a compassionate statement like "Wow. I sure do feel for those people in the path of the storm."

Same here. or holing up with friends further west.

in most general cases yes. but in some special cases where the water is moving so rapidly over an object and could create the beginnings of cavitation and take some pressure away.

Yayyyy finally stickied! I guess my Help Board thread did the job

I ain't no enjamaneer or nothin but I saw this flood wall going up in person and I just don't see how it will stop the Mighty Mississip.

I'm just curious...I grew up in the little town of Waterproof, not far from Ferriday, a long long time ago...Is this little town protected? I sorta remember the levee's in Waterproof but I was like 6 when we moved away from there.
Anybody Know?

Every town close to the river and NOT on a bluff is in danger. 65 ft is on par with a 500 yr flood for perspective.

Waterproof does have a levee. There is a spot just South of Great River Grain that has been suspect for years. This flood has a good chance of exposing that weak spot.

People do not realize what is happening. We are about to witness something that your grandkids will be asking about after hearing of it in school.

That's kinda my beef with the earlier posters making fun. This is kind of a big deal. Hopefully turns out to be something cool to watch if the Corps can designate flood plains via TNT and the levees hold. The nightmare scenario starts if levees don't hold. I listen to 95.1 in mornings on way to work and DJ said the projection of 65' is almost 1 foot higher than 1927. If 67' is a possibility then shite just got really fricked up.
