Engineer's hubris. You know, like the Space Shuttle and WTC. No, seriously, the Superdome is not below sea level so it should be relatively safe from flooding. Honestly, they're guessing whether it'll be sufficient. There is a reason it is *not* being called a "shelter" by the officials but rather a "destination of last resort." They're very careful about that.
Supposedly the roofing has been replaced (the panels, not the coating) recently. There are outdated wind data profiles but since they don't exactly have time to dream up an alternative.
regarding that Superdome, earlier there was discussion of the variance of the winds destructiveness with windspeed. I noted that the power was cubed with speed. I may have been confused, but I rechecked a wind power seb source and found this:
"An important equation used to find the wind power density, how much power is available per square meter is the equation
P = .5 pu³
, where P is the wind power density in W/m2, p is the density of the air, and u³ is the cube of the wind velocity.
An equation for the power available is :
(kinetic energy flux) = .5 p V(3) A---(that is V cubed).
, where p is the kinetic energy density J/m³, V is the velocity of the wind, A is the cross sectional area of the wind on the turbine."
It seems to me, the energy of the wind is related to the cube of the velocity. I would naturally assume that the destructiveness will be related directly to that kinetic energy.
