Performance-Based Coastal Engineering Framework
The changing dynamics of coastal regions and climate pose severe challenges to coastal communities around the world. Such challenges are exacerbated by an increase in population over time coupled with the aging of existing infrastructure, rise in property value, and the expected shifts in the …

The coastal engineering effects of Tropical Cyclone Chloe, Port Headland, Western Australia February 1984
A review of the effects of tropical cyclone Chloe off Port Hedland in February 1984 is presented. Data on waves and storm surge has been collected and successful methods developed for analysis. Of interest is the investigation into the recovery of wave parameters from relatively deep sub-surface …

Oceanographic considerations for the management and protection of surfing breaks
… there is little specific research on surfing and coastal management. Such research is required because coastal engineering has had significant impacts to surfing breaks, both positive and negative. Strategic planning and environmental impact assessment methods, a central tenet of integrated …

Análise das variações morfodinâmicas por funções ortogonais empíricas - Praia do Flamengo (RJ)
… provide information for making decision in the coastal management, and to guide future works of coastal engineering. The profiles measured by survey were analyzed by EOF method (Empirical Orthogonal Functions). Also, there were performed grain size analysis, coastal circulation cells study, and …

Models for ocean waves
… represent an important design factor in many coastal engineering applications. Although extreme wave height is usually considered the single most important of these factors there are other important aspects that require consideration. These include the probability distribution of wave heights, …

Coherence Between Wind and Current Events in a Nearshore, Shallow Water, Wave Dominated Environment
… from shore at the U.S. Army Corps of Engineers Coastal Engineering Research Center field facility at Duck, North Carolina beginning five May 1978. The current was measured with a state-of-the-art electromagnetic current meter having a 0.2-second response time and an accuracy of (+/-) 2 …

Variabilidad espacio-temporal de la porosidad de la arena tras una regeneración de playa
Coastal erosion is a natural phenomenon that is a growing problem. Over the last few decades, there has been a gradual change from hard to soft coastal defence techniques. In this sense, periodic artificial nourishment is widely regarded as an acceptable method of beach and dune protection and …

Wave boundary layer hydrodynamics and cross-shore sediment transport in the surf zone
Coastal erosion and, more generally, evolution of the beach morphology are major coastal engineering problems. Changes in beach morphology mostly occur in the nearshore region, or surf zone. They are caused by the local imbalance of sediment transport, both in long-and cross-shore directions. …

Development and Uncertainty Quantification of Hurricane Surge Response Functions and Sea-Level Rise Adjustments for Coastal Bays
… Probability Method (JPM), are critical in the coastal engineering profession. The JPM has become the preferred surge hazard assessment method in the United States; however, it has a high computational cost: one location can require hundreds of simulated storms, and more than ten thousand …

Adapting to Rising Sea Levels
… also increased erosion and gradual inundation of coastal property. At the same time, coastal populations in the United States continue to increase rapidly: over half of all Americans live in coastal counties, and at least 25 million more people are expected to move to the coast by 2015. The end …

Wave effects on underwater vehicles in shallow water
… water to complete oceanographic missions, coastal engineering surveys, and in military operations that involve reconnaissance and the location of mines along hostile coastlines. Control in the vertical plane is mandatory so the vehicle does not hit the bottom or broach the free surface. …

Experimental and theoretical study of turbulent oscillatory boundary layers
Sediment transport is of crucial importance to engineering projects in coastal regions, so it is of primary interest in coastal engineering. The driving forces for sediment transport are mostly determined by the hydrodynamics of oscillatory turbulent bottom boundary layers, which is still not well …

Long Waves In Channels Of Non-Uniform Cross-Section
… applications in the field of hydraulics and coastal engineering. As an example, for long distance propagation of landslide tsunami in fjords, travel-times and maximum wave heights can be rapidly estimated from one-dimensional governing equations, making the present theory suitable for warning …

Understanding Climate Change Adaptation and Gentrification through the Framework of Uneven Coastal Development in Keansburg, New Jersey
<p>This study examines the rapid acceleration of coastal development in the United States despite projections of climate change-induced sea level rise. Like no other developed country, the U.S. has transformed its fragile coastline into sites for leisure, consumption, and retirement. These spaces …

ISPH Modelling of Solitary Wave Interaction with Permeable Beaches
Coastal areas are vulnerable to natural disasters such as storm surges and tsunamis. Dykes, wave-absorbing blocks, and forests, are typical solutions to mitigate coastal disasters. In coastal engineering, these protections and beaches are considered as porous media. Accurate prediction of wave …

SHORELINE DYNAMICS OF SOUTH AFRICA USING SATELLITE IMAGERY
… to further the understanding of South African coastal dynamics both locally and regionally, and to demonstrate the utility of the database. For example, (i) A study of the Tugela River Mouth revealed shoreline erosion of several hundred metres from 2005 to 2023, which is important information …

Green water and loading on high speed containerships
… breakwater for a ship. In other sectors such as coastal engineering, the methodology can be adopted to investigate the interaction between water surge and a seawall or offshore breakwater. In conclusion, it was found that the developed modelling framework shows potential for simple modelling of …

A study of breakwater gap wave diffraction using close range photogrammetry and finite and infinite elements.
… gap diffraction diagrams given in popular coastal engineering design manuals. Breakwater gap configurations with the following gap width to wave length ratios (B/L ratios) were analysed, both experimentally and numerically, namely: B/L = 1,64; 1,41; 1,2; 1; 0,75; 0,5. These configurations …
