Management of erosion hazards essentially involves retreat or protection. Where hard coastal protection structures are selected, the aesthetics and amenity benefit, in addition to the protection functionality, are subjected to ever-increasing scrutiny. With legislative changes in NSW essentially limiting temporary coastal protection to sand-filled geocontainer structures and decision-makers becoming more stringent about hard structures, the demand for temporary structures is also on the rise. This presentation will cover four recent, completed case studies in NSW including two temporary medium-term structures at Stockton (Newcastle) using geocontainer and Rock Bags and two longer term hard structures at Kingscliff (Tweed Shire) and Avoca (Central Coast). Innovative solutions have been developed for the varying design scenarios.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

The port is located on the Hunter River, a major river in NSW having a catchment area of approximately 37,000km2 and a length of approximately 460km. The river is subject to freshwater flows and major flooding which introduce fluvial sediments to the port. Marine sediments are also introduced into the port entrance area by coastal processes. Continual maintenance dredging is required within the port to ensure safe navigation. It is fundamental to the continued operation and viability of the port.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

For these tasks, a reliable availability and high quality of the data is crucial. However, water level data from tide gauges contain technical errors as well as anthropogenic and natural influences. For the German North Sea coast and estuaries, resulting water level anomalies are partially detected and corrected manually by qualified personnel and further considered by individual subsequent users of that data. Figure 1 shows an example of such a correction of water level anomalies around tidal low water from tide gauge data at Husum, Germany, in 2016. In general, manual quality control leads to different handlings and thus incomparable results. Consequently, a uniform and automated pre-processing is needed for tide gauge data in Germany in order to detect, correct, and classify anomalies ideally in real time. The developed pre-processing approaches will not be limited to tide gauges in Germany but can be globally transferred or be extended to river sites.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

Increasing concerns on challenges posed by climate change to maritime boundaries in the Pacific, and the need for decision-ready products motivated the development of a methodology of climate change risk assessment tailored for the Blue Pacific. The aim of this work is to develop a methodology to address the implications of climate change on maritime zones considering technical, scientific, and legal aspects. The methodology consists of a climate change risk assessment to the maritime features used to generate maritime zones by the states under analysis. The aim of this assessment is to identify and prioritise features with the highest risk of destabilising maritime zones, to conduct in-depth analysis, and to recommend adaptation options.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

With early settlers holding large tracts of land, once connected to Sutherland by a steam train from 1911, the seaside holiday village of Cronulla was quickly subdivided and became a permanent town, with increasingly expensive infrastructure built along the foreshore. The sandy beach and dunes of North Cronulla, where the main settlement was established, has a well-documented history of being impacted by coastal erosion events over the past 100 years. Modification of the foreshore started around 1919, using dune sand to infill the low-lying swamp in the hind-dune, creating more ‘useable’ land. The recommendations and forward plan to prolong the life of the Prince Street Seabee seawall will be the subject of this presentation.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

It is a 521,000-acre delta located around the three main distributaries (Southwest Pass, South Pass, and Pass-a-Loutre) off the terminal end (Head of Passes) of the Mississippi River. Here, the delta is a highly productive ecosystem that serves as a refuge for migratory birds, harbors fisheries, and acts as defense mechanism against storm surge for the city of New Orleans. Over the past several decades, the wetlands of the eastern BFD have experienced severe degradation. The primary cause of wetland loss in this area is the combination of relative sea level rise (RSLR) and decreased hydrologic connection to the Mississippi River, which results in insufficient sediment deposition and increased salinity. The BFD restoration project proposes to restore the hydrology and improve the freshwater and sediment delivery to the Eastern Bird’s Foot Delta through dredging some combination of the three largest distributaries south of Head of Passes (HOP). To inform restoration efforts, Mott MacDonald (MM) performed extensive modeling efforts to evaluate the influence of salt wedge on hydraulic and morphological patterns across the BFD.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

In addition, to mean sea level rise, it is important to estimate future changes in extreme sea levels due to storm surges and ocean waves for coastal adaptation purposes. This study aims to estimate the climate change impacts on both global waves and storm surges under an extremely high-resolution Global Climate Model (GCM) forcing continuously over 150 years, starting from the mid-20th century and extending to the end of the 21st century as the climate warms.

In transition zone areas that are subject to compound flood effects, using models that neglect rainfall and river contributions may lead to under-designed levee and floodwall elevations that do not meet the project’s intended level of risk reduction. Without the proper characterization of total water level statistics, CSRM designers often pick more unlikely and perhaps overly conservative design scenarios (ie 100 year storm surge plus 100 year rainfall plus 100 year riverine flood). The neglect of compound flood physics influences important calculations typically involved in coastal project planning such as annual expected damages, project costs, benefit cost ratios, making it difficult to plan and select optimal infrastructure.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

Extreme surface waves associated with storm systems generate coastal flooding and erosion that can impact coastal populations and infrastructure. The large roughness of healthy coral reefs has the potential to significantly attenuate this wave energy prior to reaching the shoreline through the drag forces that coral roughness exerts on the water column. The magnitude of these drag forces is dependent on how the complex geometries of corals interact with wave-driven oscillatory flows. This interaction is most commonly described both physically and numerically with idealised models of canopies, typically using arrays of submerged cylinders that lack the natural complexity of coral reef roughness. A physical modelling approach with a canopy of complex coral shapes is needed to sufficiently investigate the properties of the canopy which best represent their interaction with wave-driven oscillatory flows resulting in the attenuation of wave energy. In this study we investigated the performance of a coral reef restoration approach developed by MARS Inc. to attenuate wave energy across a range of incident wave conditions, water depths and coral cover.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...
