Abstract
    More than 131 X 106 mt of inorganic sediments accumulated in coastal wetlands when Hurricanes Katrina and Rita crossed the Louisiana coast in 2005, and another 281 X 106 mt when prorated for open water area. The annualized combined amount per hurricane equals: i) 12% of the Mississippi River's suspended load, ii) 5.5 times the inorganic load delivered by overbank flooding before flood protection levees were constructed, and, iii) 227 times the amount introduced by a river diversion built for wetland restoration. The accumulation from hurricanes is sufficient to account for all the inorganic sediments in healthy salt marsh wetlands.
