Long-term erosion due to natural coastal processes have caused the iconic vibrant red cliffs of the Redcliffe peninsular (Scarborough, Queensland, Australia), to retreat landwards, which posed a potential risk to public safety and infrastructure. Investigations into coastal processes and geotechnical conditions at the site found that the retreat of the 320m long section of cliffs was largely driven by the slow notch erosion of the cliff base resulting in translational block failure of the overlying laterized cliff face and rotational collapse of the weaker cliff crest soils. To prevent continued notch erosion of the cliff base and subsequently improve the overall stability of the cliffs, a ‘lower cliff hardening’ solution was developed. This solution comprised of a coloured and textured, soilnailed, glass-fibre reinforced polymer reinforced shotcrete wall, which aimed to replicate the natural form and aesthetic of the existing lower cliff.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

In particular, a megathrust earthquake has a potential to cause severe damage to cities almost simultaneously in terms of both seismic ground shaking and tsunami damage. However, in the countermeasures against future disasters, seismic and tsunami damage are generally assessed separately, and different source models are assumed for different types of disasters. This study aims to calculate damage probabilities of ground motion and tsunami for buildings in a coastal city under the same earthquake scenarios and to make an intercomparison between these two kinds of hazards.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

The several other accidents occurred at this beach in recently years. Firstly, we check the weather condition and the wave condition. Secondary, we conducted the field survey in August 2018. In the field survey, we used ADCP, and we got the water depth information and the current information. When we used the ADCP, this device and GPS device attached to a watercraft. During conducting the field survey, we got the aerial photographs by the UAV. The photographs were used to make a grid topographic data. Thirdly, we simulated the wind driven current in Ishikari Bay, and the wave current around Zenibako Beach. Finally, we considered the reason why the accident occurred. Our final purpose of this research is to obtain the knowledge for preventing the occurrence of water accidents. To obtain the knowledge, we grasped the mechanism of drowning by grasping the topography of the field and dynamics of the seawater when the water accident occurred.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

In this regard, creating a wave forecasting system could facilitate vessel movement at the harbour entrance or inside the sheltered area. Wave characteristics are usually estimated using numerical models, which generally require high computational costs, making them inadequate for nowcasting and forecasting wave climate. The current study describes the implementation of a forecasting methodology for the port area of Augusta (Sicily) based on an Artificial Neural Network (ANN) that attempts to deliver a trustworthy response and the numerical model but with a significant reduction in the computational time.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

The results of that comparison and some details and challenges of the numerical model are addressed in this paper. The agreement between measured data and CFD results is excellent, demonstrating the ability to provide effective design support despite a range of numerical challenges.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

This method, however, requires a high-performance computer and a large cost of computational resources. With the development of neural networks, which can compute at a low cost, the use of neural networks in wave prediction has recently been studied. However, because a large amount of training data is required for neural network tasks using scarce datasets, it is difficult to predict wave conditions accurately. Fan et al. (2020) reported that using LSTM model for prediction of significant wave height (Hs) was higher accuracy than conventional neural network model. Additionally, they recommended using at least 2 years of training data for 6h predictions, that is, an excessively small amount of data is not presumed to predict sufficiently Hs. Therefore, we propose a wave prediction method using transition learning. Transfer Learning is the method of transferring trained knowledge from one model to another. In this study, we investigate whether transfer learning can be used to improve the performance of Hs prediction by transferring the knowledge learned at Sakata port, which has a large amount of training data, to the coast of Yamagata, which has a scarce one.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...
