MS Plan B Defense: Modeling of hurricane waves for design of coastal infrastructure
Zoom Meeting ID______ 853 4276 3602 Passcode: U7H0uXGiannicola Tumino Di Costanzo Graduate Student Department of Ocean and Resources Engineering University of Hawaiʻi at Mānoa The subtropical Hawaiian Islands are subject to occasional hurricanes that bring the risk of infrastructure damage and financial loss. Determination of hurricane wave conditions in terms of return period is important for coastal infrastructure design and risk management. This study assembles and validates a hurricane wave model and utilizes the model to determine probabilistic design wave conditions for a study site at west Maui. The Delft3D software, which includes a parametric hurricane model and SWAN (Simulating Waves Nearshore), is used to determine significant
MS Plan A Defense: Morphodynamic changes due to calm-moderate wave forcing: A case study of Waikiki Beach
Zoom Meeting ID______ 999 8388 9554 Passcode: OREJulianne Kalksma Graduate Student Department of Ocean and Resources Engineering University of Hawaiʻi at Mānoa Sea level rise, erosion, and the wave climate influence Waikiki Beach on the South Shore of Oahu which is a popular beach in metropolitan Honolulu. In response to recent erosion events and ongoing beach nourishments, weekly surveys have been collected for the past 3 years, from April 2018 through December 2020, to better understand coastal morphology. Local studies found detailed two-dimensional morphological structures; however, no direct relationships between the offshore driving ocean conditions and Waikiki Beach have been established. Other previous works relate the wave
Seminar: Flood and Erosion Hazard Mitigation for North Shore, O’ahu
https://hawaii.zoom.us/j/93596087383Jonathan Chapman, John Melve & Andrew Storey Graduate Students Department of Ocean and Resources Engineering School of Ocean and Earth Science and Technology University of Hawaiʻi at Mānoa Zoom Meeting Link: Meeting ID: 935 9608 7383 Passcode: OREseminar https://hawaii.zoom.us/j/93596087383 The ORE 783 Capstone Design course invited detailed proposals from engineering students for FEL-1 and -2 level studies.

MS Plan A Defense: Seasonal wave climate anomalies on the North Shore indicative of erosion conditions
https://hawaii.zoom.us/j/98606638344Andrew Storey Master’s Student Department of Ocean and Resources Engineering University of Hawaiʻi at Mānoa Zoom Meeting Link Meeting ID: 986 0663 8344 Passcode: ORE https://hawaii.zoom.us/j/98606638344 Sea level rise and seasonal wave climate have beset the Sunset Beach shoreline community with several episodic erosion events that have impacted local infrastructure. In support of the local community, the US Army Corps of Engineers (USACE) Honolulu District has employed a series of remote sensing technologies at Sunset Beach to generate a regional sediment budget to better inform the community of their situation. The objective of this study is to explain the more
Seminar: Towards an Operational Dispersive Nearshore Wave Model for Assessment of Coastal Flooding
Holmes 247 2540 Dole Street, Honolulu, HI, United StatesFatima-Zahra Mihami & Dr. Volker Roeber PhD Student, E2S Chair HPC-Waves Université de Pau et des Pays de l'Adour, France Location Information: **this seminar will be held both in person (Holmes Hall 247) and over Zoom** Meeting ID: 960 4654 5799 Passcode: OREseminar https://hawaii.zoom.us/j/96046545799 This will be a joint seminar between ORE and CIMAR. Quantitative assessments of wave-driven run-up and inundation scenarios have been of high interest for coastal residents, engineers, emergency managers, and scientists. Computational approaches of coastal flooding from waves only have been widely based on empirical formulations but nowadays make increasingly use of numerical models. Due to

Dr. Roger Wang Assistant Professor Civil and Environmental Engineering Rutgers School of Engineering Location Information **This seminar will be held over Zoom** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/9616222236 In the big data era, do you often feel the opposite: I need more data for my research? As data science and data-driven algorithms emerge, there is an opportunity to develop and apply new methods of data mining from unconventional data sources. In this talk, I will show a few examples from my lab related to coastal resilience. In these examples, AI can extract valuable and unprecedented quality data
Seminar: Using Distributed Acoustic Sensing to observe surface gravity waves and nearshore processes
Watanabe 112 2505 Correa Rd, Honolulu, HI, United StatesDr. Hannah Glover, Postdoctoral Scholar Dr. Meagan Wengrove, Assistant Professor of Coastal Engineering College of Engineering, School of Civil and Construction Engineering Oregon State University| Location Information **This seminar will be held both in person (Watanabe Hall 112) and over Zoom** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 Distributed acoustic sensing (DAS) uses an interrogator to send pulses of laser light down fiber optic telecommunications cables. The coherent backscattered return of light from impurities in the manufactured glass to the interrogator can be used to sense environmental signal. Phase shifts in the backscattered light are directly related to cable

Watanabe 112 2505 Correa Rd, Honolulu, HI, United StatesShijie Huang, PhD Candidate Department of Ocean and Resources Engineering University of Hawaiʻi at Mānoa Location Information **This seminar will be held both in person (Watanabe Hall 112) and over Zoom** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 Devastating tsunami waves can mobilize a substantial amount of coastal sediments, causing significant morphological changes to the coastline. To understand the underlying hydrodynamics and sediment transport mechanisms associated with tsunami waves, a three-phase (air, water, and sediment) flow Computational Fluid Dynamics (CFD) model based on OpenFOAM was used to simulate the beach erosion induced by breaking tsunami-like waves. In this talk,
Experimental and numerical investigation on the runup of leading-depression N-waves
Zoom Meeting ID: 961 6222 2366 Passcode: OREseminarDr. Peter Lo, Assistant Professor Department of Engineering Science and Ocean Engineering National Taiwan University Location Information **This seminar will be held over Zoom only** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 Solitary waves, widely used benchmark waves in hydrodynamic studies, had historically been implied as a suitable wave form for tsunamis. However, modern tsunami records reveal solitary waves to be an inaccurate model for real tsunamis. For example, before the arrival of a tsunami at shore, a significant recession of water is often observed. Solitary waves are incapable of capturing this drawdown phenomenon, and the leading-depression N-waves (LDNs)

This means that the frequency of the incident wave must match the resonant frequency of the converter. This resonant frequency is influenced not only
