Nature based solutions for coastal defense: Wave attenuation and economic analysis of marsh-fronted seawalls
… 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 friction. In particular, the vegetation drag …

Projections of Mangrove, Saltmarsh, and Oyster Reef Viability in the US East Coast and their Role in Coastal Defense
… I demonstrate that each of the analyzed eco-defenses can be used as part of a coastal defense plan.I began with a broad top down survey of the entire region. I created a series of viability maps for each eco-defense under all analyzed scenarios for the entire region. From here, I found the …

Evaluation of Optimized Architected Reef Design in Random Oscillatory Motion for Maximized Wave Energy Dissipation and Coastal Preservation
The mitigation of exacerbated coastal erosion and reef degradation warrants thorough examination and enhancement of existing coastal defense strategies. Severe threats to ecosystems, communities, and infrastructure from climate change, including rising sea levels and intensified weather events, …

Relationship between coastal vegetation biomass with elevation and salinity gradients
… damage to property and loss of life in coastal areas. Vegetation in wetlands and coastal fringes can reduce storm surges and waves while complementing traditional coastal defense approaches such as permanent levees, seawalls and gates. The effectiveness of marsh vegetation in attenuating …
