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 …

Numerical Perspective on Tsunami Hazards and Their Mitigation by Coastal Vegetation
… most threatening natural hazards that can affect coastal communities and infrastructures. In order to provide useful information for coastal protection, one of my aims in this dissertation is to identify the physical metrics that better represent the damage cause by tsunamis. I approach this …

Machine Learning and remote sensing applications to shoreline dynamics
Coastal communities and land covers are vulnerable receptors of erosion, flooding, or both in combination. The accurate, automated, and wide-scale determination of shoreline position, and its migration at the engineering scale (10-1 – 102 km), is imperative for future coastal risk adaptation and …

High-Fidelity Numerical Simulation of Shallow Water Waves
… impose significant threat to human life and coastal infrastructure. The goal of my dissertation is to develop a robust, accurate, and computationally efficient numerical model for quantitative hazard assessment of tsunamis. The length scale of the physical domain of interest ranges from …

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 …

Statistical and process-based models for understanding species distributions in changing environments
… and legacy effects, I assess the resilience of coastal vegetation to abrupt hydrological changes. According to the results of the resilience analysis, I then modify temporal SDM predictions, thereby transferring relevant process detail from PBM to SDM. The direction of knowledge transfer from …

The effects of population size on agathosma collina (rutaceae) and its conservation implications
… outcrossing shrub species, endemic to the coastal vegetation between the Agulhas Plain and Heidelberg in the Southern Cape. Although not a rare species, its endemism makes it a suitable candidate for a study of population size effects and the conservation implications for similar …

Assessing the ecological vulnerability of natural flood defences and risks to agricultural land following seawater flooding
… severity of storm surge flooding in low-lying coastal regions is projected to increase under future climate scenarios. There is a growing need to understand how these events will impact coastal ecosystems, and the measures that can be taken to mitigate against these effects and protect natural …

Potential Wave Impacts On Shorelines In Intertidal Waterways
Coastal erosion is caused by a deficit in the sediment balance along coastal shorelines. Within the intertidal waterway of Jacksonville, Florida, the primary processes acting on the shoreline are tidal currents and waves generated by winds and passing vessels. This study focuses on the analysis of …
