Statement: Salinity intrusion in the Wax Lake delta due to hurricane Ike
Abstract: Hurricane Ike developed in early September and passed over Cuba. It did heavy damage in Cuba (it was one of the most expensive hurricanes for that country ever). Ike developed in a category 2 hurricane and made landfall near Galveston, TX on September 13th, 2008.
This animation shows results of a Delft3D simulation to study the effects of Hurricane Ike on the Wax Lake delta in Atchafalaya Bay, Louisiana (USA). The model domain is 25 by 30km. The movie shows salinity before, during and after this hurricane event. Water in the Wax lake delta is relatively fresh, during the entire period there is continuous river discharge being fed into the delta system. The river discharge is more important during low tide and brackish water progrades into the delta during high tides under normal conditions. This is the pulsing of the system you can see in the beginning of the simulation. Hurricane Ike brings much more saline water into the delta (the red color), at the peak of the event the entire delta is submerged and the salinity approaches Gulf of Mexico values (20-25 ppm). Note that saline water persists long in some of the Wax lake wetlands: even on the 18th of September, 5 days after the actual landfall there is still high salinity. This had a major effect on the wetland vegetation and killed much of the freshwater/brackish water tolerant species
