Abstract:
Marsh edge erosion has been documented by Penland and co-workers as a significant contribution to overall land loss. The gradual expansion of coastal bays is critical to the development of barrier islands and also allows for positive feedbacks between increasing fetch length and wave erosion. The role that the size and location of open bays plays in storm surge dynamics has been the subject of study since Hurricane Katrina. In the conceptual model, increased surge and wave activity over the marsh disturbs the surface only if the soil is dominantly organic. Otherwise, there is a net contribution of mineral sediment, aiding vertical sustainability.
