Video on Fox shows water pouring over top of repaired levy (9th Ward). Corps of Engineers calls it "seepage". I call it overflowing. If the water on the back side keeps going up, the flow will clearly intensify, based on that video.
Here's the thing. If the water in the Industrial Canal is high enough to flow over the top of the sandbag repairs, which are close to the original height of the seawall there....then the water on the Gulf and in the MRGO is high enough to pour through hundreds of full breaches on the east side of St. Bernard Parish.
If it follows the form it did during Katrina, you'll see the Canal breach put water on the ground first, but soon the flow from the east side will overwhelm the smaller canal breaches. It has further to go, so it takes longer to get there, but the holes are orders of magnitude larger.
That's why the barge was inside the breach, but the water was pouring out.
