Ian Robertson Environmental Data Analyst Applied Research Laboratory University of Hawai'i at Mānoa 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 Regions with high-energy wave environments, such as the Hawaiian Islands, can experience wave-induced erosion that impacts coastal infrastructure. Structures such as pile breakwaters and other slotted/perforated structures have been proposed to dissipate the wave energy. The thickness of these structures is very small compared with the wavelength so they can be regarded as thin-walled structures. In this talk, I will present some preliminary
