Cyclone Storm Surge
Wetland loss on the hurricane-prone Louisiana coast continues at an alarmingly high rate. The coupled flow-wave Delft3D model was applied to study the effect of land-building projects in this area. Numerical experiments showed that the proposed project in Barataria Basin would reduce both surge and waves in construction areas, while to the south of the project, surge and waves would increase. The project in Breton Basin would reduce waves nearby with little effect on surge under an Isaac-like hurricane. Model results also indicated the importance of other factors, such as delta morphology, vegetation and relative sea level rise.
