Seawall
Seawall consists of two self-contained selections of fiction from a larger project. Seawall follows a young man named Million Horizon from the moment he arrives in Galveston, Texas, in September of 1900 along with the historical hurricane that would come to be known as the Great Storm of Galveston. …

EPIBENTHIC INVERTEBRATES AND JUVENILE CHUM SALMON (ONCORHYNCHUS KETA) PREY AVAILABILITY ALONG AN ECO-ENGINEERED SHORELINE: A CASE STUDY AT THE SEAWALL IN SEATTLE, WASHINGTON
… and benefit shoreline dependent species. Seawalls and piers can reduce the quality and quantity of shallow water habitat available to out-migrating juvenile salmon (Oncorhynchus spp.) by deepening nearshore water and shading the shoreline environment. Previous studies along Seattle’s …

Morphological Change of a Developed Barrier Island due to Hurricane Forcing
… the wave-force reducing capabilities of a buried seawall, the effects of bay surge on morphological change and the effectiveness of adaptation strategies to rising sea levels. According to simulation results, a buried seawall located beneath the nourished dunes in Bay Head reduced wave attack by a …

AN EMPIRICAL STUDY OF FLOOD WAVE IMPACT PRESSURES TO DETERMINE THE EFFECTIVENESS OF NEW SEAWALL DESIGNS USING A DAM-BREAK APPROACH
… to reduce both their occurrence and severity. Seawalls of varying slopes with wave energy dissipaters to create various degrees of roughness on their surfaces have been proposed as a potential evolution in the design of coastal defences. This present study therefore aimed at investigating the …

Nature based solutions for coastal defense: Wave attenuation and economic analysis of marsh-fronted seawalls
A seawall fronted by salt marshes is a hybrid, 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 …

Concrete ecological enhancement in the temperate marine environment
… crabs with artificial rockpools and the adjacent seawall at high tide were monitored between April and October in a temperate harbour. Using video footage, it was possible to ascertain the length of time bass, shore crabs, and shanny spent in each habitat and what behaviours they engaged in. More …

Micro-modelling of wave fields
… elements in marinas, 2. develop a new composite seawall for overtopping based wave energy conversion and 3. test geometry variations in an existed yacht harbour. The obtained experimental findings demonstrated that the micro-modelling of non-breaking waves is possible for water depths larger than …

SPH Modeling of Solitary Waves and Resulting Hydrodynamic Forces on Vertical and Sloping Walls
… a flat vertical wall as well as a sloping seawall. The analysis includes comparisons of the numerical results with published experimental data. The model is shown to accurately reproduce the formation of solitary waves as well as their propagation and breaking. The impacting bore profiles …

Wave impacts on rectangular structures
… function to estimate the wave climate at the seawall. What is more, the higher spectral moments will generally be unknown. Wave breaking, according to linear wave theory, is known to depend on the wave spectrum, see Srokosz (1986) and Greenhow (1989). Not only is the wave climate unknown, but …

Impacts of Hard Stabilization on the Shore of Yellowstone Lake, Yellowstone National Park, Wyoming, USA
… impacts associated with shore armor (i.e. seawalls and riprap) are a common topic within the coastal community. While many agree that the installation of these structures alters the shores geomorphic response, there is disagreement in the type and degree of response. Furthermore, studies …

Green water and loading on high speed containerships
… 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 green water in which the behaviour of the water and its loading effects could be well reflected. It was …

Ecological role of mining ponds in Southern Coastal Mines, Namibia
… coastline has involved the construction of seawall berms to advance the coastline and permit mining in previously subtidal areas. Large areas are mined out to bedrock level by the removal of overburden (sand and gravel), and after mining is complete, areas behind the seawalls fill with …

Extreme weather disaster resilient port and waterway infrastructure for sustainable global supply chain
… hazards. In response to SLR and tsunami, the seawall around port infrastructures should be improved and raised to 2 m height to protect life infrastructure and communities in the port cities. This research will benefit port authorities, maritime and waterway cargo shipping enterprises, and …
