Analyzing remote sensing-derived normal difference vegetation index to predict coastal protection by Spartina alterniflora
Coastal vegetation can provide protection to the coastline through its root structures, which reduce soil erosion, and its stem structures, which dissipate wave energy. The drag a plant induces could be used to quantify the amount of coastal protection that is provided. This study combined field …

Impact of Patchy Vegetation on Wave and Runup Dynamics
Coastal regions are vulnerable to various natural processes, ranging from normal waves to extreme events. Given the flourishing development and large population along coastlines, various measures have been taken to mitigate the water-induced damage. Nature-based coastal protection, especially …

A Regional Assessment of Coral Restoration within the Western Atlantic with a Case Study of Barbados
… US$ per year through ecosystem services such as coastal protection, fishery and tourism. Unfortunately, the hard coral global coverage is rapidly declining. Especially the coral reefs of the Caribbean Sea have experienced a severe deteriorating in the last four decades. Many projects have sought …

Numerical Study of Metamaterial-Inspired Water Wave Control Technologies
Ocean waves serve as both a coastal hazard and a renewable energy resource. On one hand, they drive erosion and flooding, posing significant risks to coastal communities. On the other, they offer a vast but largely untapped source of sustainable energy. Addressing these challenges requires …

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 …

Wave Mechanics in Constructed Oyster Reefs and the Design of Nature-Based Coastal Adaptation
… oyster reefs (CORs) to function as nature-based coastal protection infrastructure, but most projects to-date are designed primarily for wave attenuation and fail to consider both the environmental conditions necessary for long-term oyster reef sustainability as well as the importance of education …

A Comparison of Natural, Living, and Hardened Shorelines Ability to Prevent Coastal Erosion and Maintain a Healthy Ecosystem
… methods, hardened, and living shorelines, of coastal protection for when the natural marsh suffers excess erosion rates. Living shorelines are a suite of shoreline conservation and restoration techniques that usually involve some sort of hardened structure that dampens wave energy so that the …
