Statement: Cumulative Erosion and Sedimentation over 3 weeks of winter storms
Abstract: This animation shows results of a Delft3D simulation to study the effects of the passage of a strong cold front on the Wax Lake delta in Atchafalaya Bay, Louisiana (USA). The model domain is 25 by 30km. The movie shows cumulative erosion and deposition due to passage of a number of cold fronts in 2008. Cold fronts pass every 4-5 days during the winter. Many of the simulations for the Wax Lake in the repository are done for hurricanes, but these particular experiments explore the effects of a cold front. They may be smaller magnitude events, but they happen many times per winter season.
It is clear that erosion and sedimentation in the Wax lake delta is in the order of centimeters per event. This November-December 2008 cold fronts cause about 5 cm of deposition at the fronts of the outermost mouthbars. There is also accumulation near bifurcations, where the flow presumably slows down. At the same time, certain local areas experience erosion due to the cold fronts (the blue spots).
