Modeling Hourly Storm Surges using Deep Learning Techniques
<p>Storm surges cause coastal flooding, one of the most devastating coastal hazards. Accurate modeling of storm surges is essential for predicting and mitigating these impacts. Traditional approaches model surges at individual tide gauges and often focus on daily time scales, leading to data …

Rapid Prediction of Tsunamis and Storm Surges Using Machine Learning
Tsunami and storm surge are two of the main destructive and costly natural hazards faced by coastal communities around the world. To enhance coastal resilience and to develop effective risk management strategies, accurate and efficient tsunami and storm surge prediction models are needed. However, …

Oceanic storm surges in the outer Mackenzie Delta, NWT Canada: Remote Sensing of tundra disturbance and restoration from saline intrusion
… et al. 2011). In September 1999, an oceanic storm surge occurred over the alluvial islands of the outer Mackenzie Delta, NWT Canada. The salt water incursion killed more than 250 km2 of freshwater tundra. Over a decade later, dead vegetation remains the dominant land cover for more than one …

Late Holocene hurricane activity and climate variability in the northeastern Gulf of Mexico
… A 4500-year record of hurricane-induced storm surges is developed from sediment cores collected from a coastal sinkhole near Apalachee Bay, Florida. Reconstructed hurricane frequency is shown to exhibit statistically significant variability with the greatest activity occurring between …

Deriving a policy document towards an early warning system for estuaries in South Africa: case study Great Brak estuary, Eden District, Southern Cape
… are becoming increasingly vulnerable to storm surges and accompanied estuary flooding. These events are largely due to increasing severity of storm surges combined with growing housing and commercial developments. A particularly severe weather event in 2007/2008 highlighted the pressing …

Relationship between coastal vegetation biomass with elevation and salinity gradients
Surges and waves generated by hurricanes and other severe storms can cause devastating 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 …

Evaluation of Tsunami Design Codes and Recommendations for Bridges Susceptible to Tsunami Inundation
… speeds of tsunamis are not typically seen for storm surges or flooding, and result in large fluid forces on structures. As a result, design codes that consider storm surges and flooding do not reflect the extreme nature of tsunami loads. In this thesis the bridge types most susceptible to a …

Incorporating local participation and GIS in assessing flood vulnerability in informal settlements : Masiphumelele case study
… to both wetland flooding and coastal storm surges. This informal settlement, south of Cape Town has rapidly expanded since its inception 20 years ago, and large numbers of economic migrants largely from the Eastern Cape have swelled the population and over-whelmed the local …

Parametric Soil-Structure Modeling for Rapid Climatic Disaster Response
… hazards, such as hurricanes and their induced storm surges, flooding, and heavy precipitation. Recent disasters of these types, such as HurricaneSandy, have afflicted millions in coastal communities and resulted in billion dollars of losses. Given disasters at such scales, field-based …

Stochastic Analysis Of Storm-Surge Induced Infrastructure Losses In New York City
… a model for predicting future hurricane related storm surge patterns and for estimating possible levels of damage from future events in order to develop planning strategies to mitigate against possible damage. The first step is to describe the frequency of past storm surge events in New York City …

Validation Of Integrated Coast-Ocean Model Cche2D-Coast And Development Of Wind Model
… Higher winds potentially generate higher storm surges and consequently larger floods occur along the coastlines. Therefore, it is critical to accurately predict winds, storm surge, and waves associated with a hurricane. In the present study, an integrated coastal and ocean process model, …

Chemical, Toxicological, and Microbial Characterization of New Orleans Sediments Following Hurricane Katrina
… 2005 Hurricane Katrina struck the Gulf Coast and storm surges breached levees flooding much of New Orleans, Louisiana. One month after the storm, sediment was collected and toxicity was tested using Japanese medaka (Oryzias latipes) embryos. Sediments with the highest contaminant levels showed the …

Earth Observation Data-Driven Assessment of Local to Regional, Contemporary, and Emerging Coastal Environmental Security Challenges
… socio-economic processes such as sea level rise, storm surges, hurricanes, land subsidence, and population growth. The coastal U.S. is highly vulnerable to many of these climate and human-induced stressors. Over the past three decades, sea levels have risen by about 0.1 m along the U.S. coasts, …

Pavement Resilience Assessment Using Pavement Condition Data Before and After Hurricane Harvey
… the increasing risk from coastal disasters like storm surges, flooding, erosion, and rising sea levels which directly threaten civil engineering infrastructures, especially the transportation assets. This research is focused on assessing the impact of Hurricane Harvey on the pavements in the …

“We Look to the Water”: Coastal Erosion and the Transformation of shíshálh Cultural Landscapes
Rising sea levels, storm surges, and shoreline erosion are ongoing climate change effects that have produced tremendous impacts on Indigenous cultural heritage across the world. Few available studies have focused on how these impacts will affect heritage sites and cultural landscapes on the coast …

Investigation of the Spatiotemporal Evolution of Tropical Cyclone Storm Surge under Sea Level Rise
Storm surges induced by tropical cyclones have been ravaging coastal communities worldwide, where a growing number of people reside. Tremendous life and economic losses are caused by tropical cyclones, contributing to more than half of the damages induced by natural hazards. To improve the …

Mapping the Distribution of Barrier Island Slash Pine Woodland and Determining Growth Responses of Pinus elliottii to Hurricane Katrina (2005) on Cat Island, Mississippi
… as extreme episodic events. The wind, waves, and storm surges of Hurricane Katrina heavily impacted the Mississippi–Alabama barrier island chain on August 29, 2005. Cat Island experienced a 7-m storm surge, the highest wind energy in the chain, but was estimated to have the least amount of forest …
