The subsequent Chile tsunami in 2010 and Great Japan Earthquake and Tsunami (or Tohoku Tsunami) in 2011 re-invigorated the urgency of developing design provisions for tsunami loading on coastal structures. The culmination of this experimental and theoretical research, and field reconnaissance after damaging tsunamis, resulted in the development of a new Chapter 6 “Tsunami Loads and Effects” in the ASCE7-16 Standard “Minimum Design Loads and Asso-ciate Criteria for Buildings and Other Structures”. This paper briefly reviews the ASCE7-16 tsunami design provisions. The application of these provisions to the design of new tsunami vertical evacuation refuge struc-tures in Oregon and Washington States, and new multistory residential buildings in Waikiki, Hawaii, will be presented. This paper also introduces recent modifications to the tsunami design provisions approved for the ASCE7-22 Standard published in December 2021. These modifications were prompted by recent laboratory research, observations after the earthquake and tsunami in Palu, Indonesia, and updates to numerical model-ing procedures for tsunami inundation.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

By delivering timely information about approaching coastal storms, early warning systems (EWSs) can enhance community preparedness and inform risk-reduction measures, with the goal of reducing potential impacts to property, critical infrastructure, and loss of life. Worldwide, existing coastal hazard EWSs primarily center around the forecasting of coastal flooding risks, which predominantly occur along surge-dominated coastlines. However, many of Australia’s densely populated coastlines are wavedominated, where erosion hazards feature more prominently. This pilot project has developed a multiscale, coastal hazard EWS capability for Australia that uses state-of-the-art scientific methods for predicting both erosion and flooding impacts caused by coastal storms.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

However, direct bathymetry data collection is expensive and time-consuming, while accurate airborne lidar-based survey is limited by breaking waves and decreased light penetration affected by water turbidity. Several recent efforts have been made to apply interpolation and inverse modeling approaches to indirect remote sensed observations along with sparse direct survey data points. Example indirect observations include video-based observations such as time-series snapshots and time-averaged (Timex) images across the surf zone taken from tower-based platforms and Unmanned Aircraft Systems (UASs), while stationary LiDAR tower and UAS flights with infrared camera capability or imagery-based structure-from-motion (SfM) algorithms have been used to provide beach topographic data. In this work, we present three bathymetry estimation tools for real-time nearshore characterization using different types of information.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

This formed a protective toe and was the first use of this technique on the open coast of NSW. Furthermore, a 120 m, 4 tonne Rock Bag structure was constructed at Stockton. Consideration of the potential broader use of Rock Bags for short to medium term protection prompted more research into the engineering effectiveness of the technology.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

These projects rely on natural forces to redistribute sediment in the nearshore zone and mitigate erosion, increase beach width or both. However, there is still limited knowledge on the connection between the morphodynamic development of the nourishment body and the changes to the beach landward to it. Several aspects make it difficult to connect the changes in the sub-aqueous and sub-aerial zones of the cross-shore profile, amongst others the lack of data and the small signal in beach changes with respect to the natural variability. We hypothesize that this obscurity also originates from the deep placement of most nearshore berms, making them mobilized very infrequently. This study examines observations of a unique shallow nearshore berm at New Smyrna (FL) where about 350,000 m3 of sediment dredged from a nearby inlet was deposited in the nearshore zone by moving the end of an outflow pipe along a 400-m section of coast.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

To improve existing seawalls, not only raising height of the sea walls, but also installing wave-dissipating blocks in front of the seawalls might be restricted depending on locations due to their use. In such cases, additional installation of a parapet, namely a double parapet is effective in reducing wave overtopping. The wave overtopping rate over a rear parapet fluctuates depending on the storage of a water-ponding between the parapets, which has not been studied sufficiently. This study investigates the tendency of fluctuation of wave overtopping rate according to the drainage performance by conducting three-dimensional hydraulic experiments targeting a double-parapet type seawall at an existing airport, particularly with focusing on a corner. Further, some additional countermeasures to reduce the wave overtopping rate are tested and their effectiveness is investigated through the experiments.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...

Typically, surveys are conducted in advance of a modelling exercise so as to replicate in-situ and existing conditions. These surveys only show one snapshot in time and as such do not represent conditions that are out of equilibrium from either seasonal or long-term changes. In these locations, an assessment of a timeseries of surveys would benefit the understanding of nearshore coastal dynamics. However, timeseries of nearshore data are seldom available. Traditional coastal survey technology, e.g., bathymetry from acoustic means or airborne lidar, are expensive and time consuming, and as such they are rarely conducted on a regular basis. Satellite data offers a novel solution by allowing access to very high-resolution data generated over a 20-year time period stored in easily accessible archives, including a convenient web-based application. This paper describes the application of historical satellite data to understand coastal change to a dynamic sand spit feature in Pigeon Point in Southwest Tobago.","PeriodicalId":497926,"journal":{"name":"Proceedings of ...
