As you will hear towards the end, the gulf faces storm surge frequencies that
are significantly greater than the Netherlands (by a factor of 100 if I heard
correctly, our 100 year surge is their 10,000 year surge.). Also note that the
Katrina surge far surpassed the 100 year design surge of 16 feet, Of course, it
was hard to hear that detail in all the cacophony that flooded the waves (pardon
the pun) after Katrina. I always thought the Corps got a bum-rap in that deal.
