Abstract:

The concept of rainflow comes from the fatigue damage field where it has demonstrated its appropriateness (see Johannesson, 1999). In port engineering, rainflow counting has shown some serious advantages over traditional methods such as the zero-downcrossing method but it is not widely used. This work aims at showing some applications of this technique to problems detected in port operation and reliability after briefly introducing the concept.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/_gwjsDd3yiE

Abstract:

Most numerical studies of sediment transport in the swash zone use depth-averaged models. However, such models still have difficulty predicting transport rates and morphodynamics. Depth-resolving models could give detailed insight in swash processes but have mostly been limited to hydrodynamic predictions. We present a depth-resolving numerical model, based on the Reynolds Averaged Navier-Stokes (RANS) equations, capable of modelling sediment transport and morphodynamics in the swash zone.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/PB8Vs0LJq88

Three open-source CFD models are applied to reproduce large-scale experiments of coastal wave impacts in shallow foreshore conditions: (1) a RANS model (OpenFOAM), (2) a weakly compressible SPH model (DualSPHysics), and (3) a non-hydrostatic NLSW equations model (SWASH). An inter-model comparison is done both qualitatively (time series, snapshots) and quantitatively (model performance and pattern statistics) to determine their practical applicability for this case.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/lOBMI8HGACs

Abstract:

An approach to reduce gridded forecast data to novel waveguide coordinates is demonstrated; informed by the literature on coastally trapped waves. This does not produce new forecasts per se, but reduces data to a useful model-independent physically ordered array. Discussion is limited to the Australian mainland and forecast systems currently maintained in national operations. Heterogenous forecast models are considered with regard to the development of "seamless" sea level services across timescales.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/jlJO_dxHwuw

Abstract:

Wave reflections from dredge channels are an important consideration for coastal infrastructure. A physical model study of a proposed development for the Port of Townsville demonstrated that channel reflection, and the relatively poorly understood channel concentration are significant processes that need to be considered in coastal developments. The study showed that channel reflection and channel concentration can significantly transform the local waves, resulting in complex multidirectional wave fields and higher design wave conditions.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/XsKsofNZzvQ

Full text

Abstract:

Coastal zones are often threatened by storms that elevate water levels and increase the wave energy impacting the shoreline. These storm conditions result in coastal flooding and erosion hazards for communities, threatening lives, properties and infrastructure. Coastal impact Early Warning Systems (EWSs) are currently used to alert authorities of potential impacts prior to advancing storms. Effective EWSs provide important windows of opportunity to undertake mitigating actions to minimize the damage caused by a storm.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/-U6uEHfLizA

Abstract:

Accurate prediction of coastal erosion is of importance for the investment planning of measures enhancing resilience to natural hazards. Field data on historical is generally lacking. Recent advances in deriving historical shoreline position from freely available satellite images combined with numerical modelling of shoreline erosion provide a reliable method for prediction of coastal erosion.

Full text

Abstract:

Vulnerability assessment is invaluable information for coastal managers to develop better coastal development plans. Two approaches to do so are presented here: one evaluates vulnerability from a deterministic view applying the analytical hierarchy process (AHP); the second uses a probabilistic approach based on the Latin Hypercube and Monte Carlo modeling, therefore it considers the probability distribution functions of the variables under analysis. The results show that a probabilistic approach is more suitable for the assessment of coastal vulnerability.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/WDbsVMYsnJs

Abstract:

The problem of modelling the dynamic behavior of structures under extreme hydraulic loading requires a comprehensive examination at a range of scale to develop analytical relationships in the development of scaling methodologies. The experimental program outlined here begins this process by examining the structural response of idealized wooden structures under solitary wave loading. This program will be the first comprehensive set of experiments merging structural and hydraulic modelling techniques to capture dynamic behaviour of idealized structural elements.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/tGA_77Lhc1E

Abstract:

Coral reefs encircle most of the islands in Vanuatu and provide natural breakwaters for coastal communities by reducing wave energy arriving at the shoreline acting to control both inundation and erosion. Climate Change is projected to both exacerbate coastal hazards and endanger corals. The aim of this paper is to better understand the parameters that govern hydrodynamics on fringing reef systems. The interaction between the depth, waves and currents are studied from measurements conducted in Erakor lagoon, Vanuatu.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/mPrG6NWL4dM

Out-of-plane failure is considered in the latter case. Results demonstrate that the protection offered by vegetation is substantial and can lead to a significant reduction in the vulnerability of the shielded structure.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/3H2XhLI8sZA

An innovative caisson breakwater geometry (patent pending) named "ARPEC" (Anti Reflective PErmeable Caisson) includes openings at all external and internal walls and at lateral (cross) ones, yet in a staggered pattern, to provide a labyrinthian hydraulic communication between the open sea and the internal waters. The complex sinuous water-flow within the consecutive permeable chambers thus favors wave energy dissipation as well as port water flushing and quality, with very low reflection and transmission coefficients. 2D lab model tests demonstrate the system effectiveness.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/PaUsinYO-Zo

Seawater desalination is an increasingly important technology in the supply of potable water to municipal communities. Brine created by this process is typically released back to the ocean via a nearshore diffuser into a wave-exposed climate. Despite this, little work has been published on the effect of waves on negatively buoyant jets. In this paper we outline the literature on this topic and the results of a series of computational fluid dynamics (CFD) simulations that address the role of regular waves on negatively buoyant jets.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/0085wAVVybc

Abstract:

We describe the uncertainties of altimetry-predicted bathymetry models and then quantify the impact of this uncertainty in tsunami hazard assessments. The study consists of three stages. First, we study the statistics of errors of altimetry-predicted bathymetry models. Second, we employ these statistics to propose a random field model for errors anywhere. Third, we use bathymetry samples to conduct a Monte Carlo simulation and describe the tsunami response uncertainty. We found that bathymetry uncertainties have a greater impact in shallow areas. We also noted that tsunami leading waves are less affected by uncertainties.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/zzL_XWWAQ7o

Abstract:

Australia is a distinctly coastal-focused nation, with more than 85 percent of Australians living within the narrow coastal strip. The coast is also the major economic focus of industry, trade and tourism. Australian identity and environmental values are deeply tided to life at the coast. Around Australia there is presently no state or nationally coordinated early warning capability to alert emergency managers and residents to impending damaging impacts of coastal storms. This presentation outlines the work that is underway to design and evaluate a new national-scale beach erosion EWS system for Australia.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/2HS6HrTfxfI

Abstract:

Safety and well-being of coastal areas requires eco-compatible, cost-efficient management strategies aimed at providing continuity-of-daily-life (before, during and after a flood) and at promoting adaptation to climate change. Sustainable management solutions include building-with-nature approaches, eco-friendly measures, multifunctional structures, multi-hazard interventions. The strategic planning of these solutions can be supported by GIS-based tools, that allow -through a scenario analysis- to assess risk across a range of spatial and temporal scales and to compare the environmental, social and economic impact of clusters of solutions.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/4Mx6iHwR0uI

Abstract:

The use of video-monitoring techniques is significantly increased due to the diffusion of high-resolution cameras at relatively low-costs and they are largely used to estimate the shoreline evolution and wave run-up, as important coastal state indicators to be monitored and predicted for the assessment of flooding and erosion risks. In this work, we present an integrated approach based on the results from the low-cost video monitoring systems and the numerical modeling chain by means of SWAN and XBeach to accurately simulate and predict the swash zone processes.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/nLGNneJzmIU

Abstract:

Flood risk is generally defined as the combination of the probability of a flood event and the potential losses. Flood losses might be divided in two categories, namely tangible and intangible. Tangible losses are evaluated in monetary values and hence commonly incorporated in flood risk analysis. Intangible losses, especially environmental losses, are mostly not incorporated in flood risk analysis due to the lack of appropriate and generally accepted evaluation methods. This research focuses on the development of a new approach to evaluate environmental losses due to coastal floods.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/xyiwlw3jkYo

Abstract:

Servicing the largest population centre in Australia, Port Botany is vital to the economic wellbeing of Sydney and New South Wales. The channel entrance is often subject to energetic Pacific Ocean swell, moderate tides and occasionally severe winds. In August 2019, the Port Authority of NSW (PANSW) adopted the NCOS ONLINE system to provide enhanced decision support for under keel clearance management of deep drafted vessels in Port Botany. The technical framework and real-life application of the physics-based operational system NCOS ONLINE is presented in this paper.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/uPvX_0DNjRo

Abstract:

According to the management of the Mo.S.E. system, the water level in the Venetian lagoon is maintained below a certain threshold, that however does not guarantee the complete defense of the main Piazza. Flooding of the Piazza is presently tolerated, although limitedly to a minor extent, and can/will be avoided only thanks to additional adaptation works. One of the possible flooding mechanisms is the wave overtopping, and this note investigates the efficiency, as possible mitigation option, of a small temporary barrier placed along the S. Marco quay.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/wiSF2B81wIM

Abstract:

Wind effects on wave overtopping over fully impermeable vertical sea defence is studied in a shallow water flume based on a physical model for the Livermeade defence system. The investigation is mainly focused on impulse type wave interaction with the sea defence, when the overshooting jet is high during overtopping. We are able to identify distinct types of overtopping flows where moderate wind speed is not found to be affecting uniformly in all cases. We try to find explanation of this behaviours by studying the standing waves at the defence and complementary CFD simulations.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/byRz_N9zoXk

Abstract:

In this study, the numerical simulation of tidal current and sediment transport in the Kanmon Waterway were performed by using a numerical simulation model FVCOM (Finite Volume Community Ocean Model (Chen et al. 2003)), in order to discuss the influence of the long-term fluctuation of mean water level on the sand waves. The numerical simulation results suggested that the spatial difference of the long-term fluctuation of mean water level in the Kanmon Straits slightly changes the tidal current around Tanoura Area, and consequently affects the development of sand waves.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/kfMfIVGiLKM

Abstract:

Coastal interventions are applied for modifying the equilibrium state of coastal processes in order to address coastal community's needs. In several cases, the issues caused by the introduction of one structure are solved by other engineering solutions, but also creates new side effects. Letitia Spit (Tweed Heads, NSW) is a typical example of long-term coastal management actions that led to new shoreline equilibrium. This paper aimed to outline the shoreline response of Letitia Spit to these interventions and identify the extent of the updrift impact through a long-term remote sensing analysis.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/4qrak8AtlQc

Abstract:

Buildings at the beach-dune interface, such as restaurants and (holiday) houses, affect wind-driven sand transport in their surroundings. Hereby they shape the development of the beach-dune system. This can have implications for the flood protection offered by dunes. Therefore, this research aims to understand the effect of buildings at the beach-dune interface on beach-dune morphology. In this contribution we present the results of a field experiment which focused on the effect of building size and geometry on the size and location of the deposition patterns directly around buildings.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/hlcMP7Ev1m0

Abstract:

The items of investigation include wave induced current, wave height, beach profile, shoreline change, etc. The investigation has been performed seasonally. After the construction of submerged breakwaters, a tombolo was generated behind the submerged breakwaters. This caused beach erosion in the nearby areas. Rip currents are mainly generated near submerged breakwaters, which plays a role in the transportation of sand in the offshore direction. In order to analyze the sand movement, numerical analysis was conducted. The analysis indicated that a strong rip current is generated near submerged breakwaters.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/5p2wiNSMKlM

Abstract:

Sandy beaches are typically in equilibrium with the wave climate, and changes occur when the system is perturbed. However, changes to nearshore morphology can occur when coastal structures are built and the system adjusts to a new equilibrium. An example of this is the construction of a shore-perpendicular groin that is designed to trap sediment . We investigate the capability of Delft3D model to simulate wave transformation, nearshore circulation and morphology change around a structure, driven by relatively small breaking waves at a very high incident angle.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/q_rnSiaP7WM

Abstract:

Wave loading from inundation events like storms and tsunamis can cause severe structural damage to buildings (Xian et al., 2015); therefore, it is important to predict wave loading as accurately as possible. One uncertainty in estimating wave loads during inundation events is the possible reduction of loads by sheltering from other buildings. Understanding and quantifying this effect could reduce overestimated loads in sheltered buildings and avoid over-conservative structural design. This work aims to quantify the reduction of wave loads in sheltered buildings through the analysis of experimental data and numerical simulations.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/89QblLjDBnI

This study considers the wave overtopping loads on a building behind a rubble mound breakwater using 2D numerical modelling. The building will be used as Coast Guard station in Greystones Marina, which is located on the Irish Sea. Similar studies, using physical modelling, were carried out recently by Watson et al. (2018) and Park et al. (2017). The applicability of the numerical model in predicting wave overtopping forces is discussed. Appropriate design wave conditions are considered and the resultant loads are assessed to determine their impact on the design of the proposed building.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/4tZfjVDRPT4
