Bore Generation, Propagation, and Impact on Coastal Structures
… and solitarywave breaking and the impact on coastal structures are studied in this research by employing three different theoretical approaches. The theoretical models are based on three sets of equations, namely the Reynolds-Averaged Navier-Stokes (RANS) equations, the GreenNaghdi (GN) …

Overtopping of coastal structures caused by irregular waves
… and beyond the structure were tested. The model structures tested were a 100 mm high vertical wall, a 200 mm high vertical wall and a 100 mm high wall with the seaward face inclined at 45°. It was found that the mechanism of overtopping was different for unbroken and broken waves. In order to …

The ecology and ecological enhancement of artificial coastal structures.
… sea level rise, increased storm frequency and coastal urbanisation, artificial coastal structures are proliferating worldwide. It is now vital to understand the impact that artificial structures are having on the marine environment and it is becoming increasingly necessary to incorporate …

Numerical investigation of the performance of WEC integrated with vertical wall using CFD
… from the integration of latching control and coastal structures, specifically focusing on a vertical wall, to enhance the performance of a Wavestar-like WEC. Drawing upon an extensive literature review, this study endeavours to elucidate how the coupling of WECs with coastal structures can …

Parametric Soil-Structure Modeling for Rapid Climatic Disaster Response
… changes have seemly caused acerbating impacts on coastal environments in terms of severe meteorological 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 …

Experimental investigation of small-scale breaking waves : flow visualization across the air-water interface
… contribute considerable loading to offshore and coastal structures, and furthermore, the quasi-steady bow wave on a ship increases drag and ease of detection by the bubbly wake. However, the complexity of the phenomenon has severely limited our ability to describe it and predict its occurrence. …

Controlling crystallization via interfacial engineering : patterning, fouling-inhibition, and nutrient recovery
… a leading contributor to rusting and fouling of coastal structures. However, crystallization can also be used as a purification technique for producing a variety of important chemicals. In this thesis, control of crystallization at interfaces is explored for improving sustainability across a …

SPH Modeling of Solitary Waves and Resulting Hydrodynamic Forces on Vertical and Sloping Walls
… bores that impact and significantly damage coastal structures and buildings located close to the shoreline. The damage induced by such hydraulic bores is often due to structural failure. Examples of devastating coastal disasters are the 2004 Indian Ocean Tsunami, 2005 Hurricane Katrina and …

Resident Perception of Shoreline Recession in Nags Head, North Carolina
… recession has become a major concern in many coastal communities. This concern has developed largely because of the tremendous expense associated with trying to save coastal structures from the damage, and even total destruction, that can result from shoreline erosion. While land use …

Wave impacts on rectangular structures
… much more stable, model of wave impact on the coastal structures, and forms the basis of this thesis, as follows: Chapter 1 is an overview about this topic, a brief summary of the work which will follow and a summary of the contribution of this thesis. Chapter 2 gives a literature review of …

Experimental Study of Tsunami-Induced Loads on Bridges
… guidance for estimating tsunami loads on coastal structures and bridges shows a large variation in the values estimated by the proposed equations and the lack of general agreement even on the types of forces imposed on the bridge decks. Reviewing the available literature revealed that the …

Making an Impact: Coastal Cliff Response to Individual Wave Impacts
Understanding and predicting coastal cliff retreat remains a challenging field in coastal geomorphology. Efforts to link process drivers to erosion are confounded by the complexity of processes operating, slow rates of morphological change, and the difficulty of direct field observations. Waves are …

Two fluid numerical model for coastal applications
Wave breaking is an important coastal process, influencing hydro-morphodynamic processes such as turbulence generation and wave energy dissipation, run-up on the beach and overtopping of coastal defence structures. During breaking, waves are complex mixtures of air and water (“white water”) whose …

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 …

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 …
