Evaluating Marsh Restoration Success Using Structural and Trophic Metrics on Deer Island, MS
<p>Coastal marshes in the northern Gulf of Mexico provide essential habitat for various consumer species, however, land loss has severely degraded marsh habitat in this region. Few studies have examined restored black needlerush (<em>Juncus roemerianus</em>) marshes, such as those found in …

Naturalization of Salt Marsh Restoration Sites in the Elizabeth River, Virginia, Assessed by Feeding Activity and Trophic Level of Mummichogs (<i>Fundulus Heteroclitus</i>)
… the Chesapeake Bay Program, include several salt marsh restorations. By examining gut contents and stable isotopes values (δ13C and δ15N) from mummichogs (Fundulus heteroclitus), the functional equivalency of restored salt marshes compared to natural marshes was measured. In July 2013 I collected …

Nature based solutions for coastal defense: Wave attenuation and economic analysis of marsh-fronted seawalls
A seawall fronted by salt marshes is a hybrid, nature-based solution for rural and urban coastal protection. A one-dimensional wave attenuation model was developed using first principles to capture four mechanisms that impact wave evolution: Wave breaking, vegetation drag, shoaling, and bed …

Ecological effects of ditching and ditch-plugging in New England salt marshes
<p>Anthropogenic activities in New England salt marshes have altered hydrologic flows in various ways, but unintended consequences from some of these habitat modifications have received little attention. Specifically, ditches have existed on salt marshes for decades, but the effects of these …

Multifunctional experimental assessment in a newly established Mediterranean restored marsh : marsh elevation, carbon accumulation and pollutant concentration reduction
… (Catalonia, Spain) is among the most important marsh areas in the Western Mediterranean Sea, highly valuable both economically and ecologically. Fluvial sediment reduction by dams in a relative sea-level rise (RSLR) scenario (eustatic sea-level rise + subsidence) has increased the delta plain …

Locality of Topographic Ground Truth Data for Salt Marsh Lidar DEM Elevation Bias Mitigation Using Machine Learning
… (DEMs) are crucial for modeling coastal salt marsh systems, simulating the coastal dynamics of sea level rise (SLR), and predicting storm surge inundation depth and duration. Improvements in lidar acquisition technology and data processing over the last decade have led to increased accuracy. …

Assessment of Growth Response and Patterns of Biomass Allocation by Panicum hemitomon Schultes: Implications for Thick-mat Floating Marsh Creation and Restoration
… associated with restoring thick-mat floating marsh. Initially, Panicum hemitomon growth response was assessed in conjunction with manipulated nutrient availability and hydrology. Next, I assessed Panicum hemitomon growth response in conjunction with a suite of substrate and mat or containment …

Rising Water: Harnessing the Process of Sedimentation for a Flood Resilient Coastal Landscape
… connections to the adjacent landscapes of Dyke Marsh and the George Washington Memorial Parkway. Through careful placement of breakwater infrastructure, sediment will build over time as the water rises, mitigating the effects of coastal flooding in this region. Alterations to the landscapes of …
