Galveston is the same way
and it's no coincidence that it's also the home of two of the nations worst disasters.
But that's what the part about the wetlands and marshes was about. Those areas act as buffers to the storm surge.
I gather you're none too familiar with Hurricanes. New Orleans was very, very lucky that Katrina lost steam before making landfall (CAT-3) and didn't hit directly. Don't get me wrong; Katrina was a killer among killers with a storm surge of over 25 feet; but she could have been worse. Much worse. The topography of the ocean there lends itself to huge storm surges, which are by far the most deadly of Hurricane effects. At peak CAT-5 strength; Katrina could have hit New Orleans like a 50 foot tall bulldozer, and destroyed EVERYTHING in it's path. Believe it. The record deadliest Tropical cyclone killed 500,000 people in India... and if memory serves; that was a CAT-3 at landfall as well. We've been seeing more CAT-5s lately and it's only a matter of time until one of these killers strikes.
Events like Hurricane Katrina are essentially the finger of God
and can hardly be helped. While I'm sure those clever Dutch could feasibly build a defense system; the cost would so far beyond reason that it would never happen. And even the Dutch have contingency plans for failure. New Orleans will never be equipped to handle a CAT-5 storm. Nor will anywhere else, really
but the combination of the ocean's topography, the Mississippi River and Lake Pontchartrain all on top of the fact that the city lies on average 6 feet below sea level will forever make it an absolute Death Trap during large storm events. Wanna survive a Hurricane in New Orleans? Get the hell out of New Orleans.
(And you'd best not evacuate to Galveston, either.)(A CAT-5 will chuckle at 19 ft, Cyclo, as it washes the city away.)(Again.)
