The Pacific Island Ocean Observing System (PacIOOS) wave-measuring buoy
Watanabe 112 2505 Correa Rd, Honolulu, HI, United StatesKimball Millikan, Marine Research Engineer Pacific Islands Ocean Observing System (PacIOOS) 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 The PacIOOS wave buoy program maintains an array of 16 real-time wave-measuring buoys throughout the Pacific Islands. I will discuss the operation of the program, mooring design, fabrication, the components, including a brief history of Datwell and the design challenges of the Datawell Wave Rider stabilized platform to measure heave and direction, deployment and recovery techniques of the mooring system,
Three-phase flow simulation of beach erosion induced by breaking tsunami-like waves
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,
‘Artificial Intelligence’ for Flow Control and Data Analysis
https://hawaii.zoom.us/j/96162222366 Passcode: OREseminarDr. Siddhartha Verma, Assistant Professor Department of Ocean and Mechanical Engineering Florida Atlantic University Location Information **This seminar will be held over Zoom only** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 'Artificial Intelligence' has made tremendous gains in recent years, and it is increasingly finding promising uses in various practical and scientific applications. But despite our optimistic outlook, the underlying algorithms do not possess 'intelligence' in the true sense of the word. Instead, they are extremely adept at identifying non-linear patterns in high-dimensional datasets. I will highlight how we have leveraged such algorithms to discover optimal control laws in

For this purpose, a linear continuum model is proposed based on a two-layer formulation where the floating sea ice is described as a poro-visco-elastic medium and the underlying ocean is viewed as a
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)
