  • Seminar: Towards an Operational Dispersive Nearshore Wave Model for Assessment of Coastal Flooding

    Holmes 247 2540 Dole Street, Honolulu, HI, United States

    Fatima-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

  • Seminar: AI-enabled Earth Observation for Coastal Resilience

    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 States

    Dr. 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

  • Three-phase flow simulation of beach erosion induced by breaking tsunami-like waves

    Watanabe 112 2505 Correa Rd, Honolulu, HI, United States

    Shijie 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: OREseminar

    Dr. 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)

  • The effect of water wave conditions and geometrical parameters of a fixed Oscillating Water Column Wave Energy Converter on its hydrodynamic performance

    Watanabe 112 2505 Correa Rd, Honolulu, HI, United States

    Dr. Ayrton Alfonso Medina Rodriguez Postdoctoral Researcher Applied Research Laboratory and 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 In order to achieve maximum pneumatic power in an Oscillating Water Column (OWC) device, it is crucial for the chamber to operate as close to the resonance condition as possible. This means that the frequency of the incident wave must match the resonant frequency of the converter. This resonant frequency is influenced not only

  • Seminar: A Numerical Study of Effects of Perforation Layouts on Wave Energy Dissipation Caused by a Submerged Perforated Breakwater in Front of a Vertical Seawall

    Bilger Hall 150 2545 McCarthy Mall, Honolulu, HI, United States

    Brady Halvorson Ph.D. Student Department of Ocean and Resources Engineering University of Hawai’i at Mānoa Location Information **This seminar will be held both in person (Bilger Hall 150) and over Zoom** https://hawaii.zoom.us/j/95081858686 Meeting ID: 950 8185 8686 Passcode: OREseminar Perforated structures are a promising alternative to standard sea walls and breakwaters for dissipating wave energy and protecting coastlines. Perforated marine structures can effectively remove wave energy from ocean waves by the energy loss associated with the flow through the perforations in the structure. Understanding the factors that may affect the hydrodynamic characteristics of flow through a perforated plate is important

  • Seminar: Study of Traditional Seawalls

    POST 723 1680 East-West Road, Honolulu, HI, United States

    Ned Samson Ph.D. Candidate, Ocean and Resources Engineering *In-person ONLY (POST 723)* *request Zoom Link here for extenuating circumstances by Wednesday (2/18) @ 11:59 pm HST Hunting has been facilitated by strategies to circumvent animals’ evasive maneuvers, for example by camouflage, ambush, and the use of traps. In addition to inland fish weirs, coastal enclosures imitating shallow tropical lagoons were built by Pacific engineers throughout the centuries. Along with harbors, these ancient structures are the most successful, durable examples of coastal engineering. It is interesting to speculate that these engineers understood and harnessed the secondary undulations of tides on the
