Effects of Marsh Edge Erosion in Coupled Barrier Island‐Marsh Systems and Geometric Constraints on Marsh Evolution

Overwash Deposition Increases Backbarrier Marsh Resiliency to Sea Level Rise: Insights from a Coupled Barrier Island-marsh Model

Effects of Marsh Grass on Diffusivity

The hydrodynamic processes associated with flow through vegetation have many implications for both natural and constructed wetlands. This study examined the effect of marsh grass on mixing rates. A flow visualization study was performed, using a laser light sheet and a video camera to obtain images of a plume of fluorescent dye. The study was performed in a laboratory flume, using wooden dowels...

Does vegetation prevent wave erosion of salt marsh edges?

This study challenges the paradigm that salt marsh plants prevent lateral wave-induced erosion along wetland edges by binding soil with live roots and clarifies the role of vegetation in protecting the coast. In both laboratory flume studies and controlled field experiments, we show that common salt marsh plants do not significantly mitigate the total amount of erosion along a wetland edge. We ...

Comparison of aerated marsh-pond-marsh and continuous marsh constructed wetlands for treating swine wastewater.

Increased swine production in North Carolina has resulted in greater waste generation and is demanding some emerging new innovative technologies to effectively treat swine wastewater. One of the cost-effective and passive methods to treat swine wastewater is using constructed wetlands. The objective of this study was to evaluate the N removal under two N loads in 3 different wetland systems: ae...

Evolution and Conservation of Tidal-marsh Vertebrates: Molecular Approaches

The tidal marshes of North America are home to a diverse collection of morphologically differentiated reptiles, birds, and mammals. We reviewed the existing molecular studies on endemic tidal-marsh vertebrates, including turtles, snakes, sparrows, rails, shrews, and rodents. We found both deep and shallow divergences from their nearest upland relatives in all geographic regions. In the Northeas...
