Seminar: Waikīkī Beach Improvement Project – Kaimana Coastal Consultants
Holmes Hall 243 2540 Dole Street, HonoluluXinyi Zhang, Maliheh Gholizadehsarvandi, Kaja Reinhardt, Scott Hellinger ORE Capstone Class *In-person (HOLM243) & via Zoom* Zoom Meeting Link Meeting ID: 890 6867 4318 Passcode: ORE Waikīkī Beach is experiencing chronic erosion due to disrupted natural sand transport, shallow reef channels, and accelerating sea-level rise. The shoreline between the Fort DeRussy and Royal Hawaiian groins has become increasingly vulnerable, with frequent overwash posing risks to public safety and adjacent properties. This project aims to implement a beach nourishment and long-term maintenance plan for Waikīkī, supported by the design of a low-crested reef-crest breakwater system intended to reduce wave energy, stabilize
PhD Defense: Innovative Coastal Defense in an Idealized Barrier Reef System
Holmes 287 2540 Dole Street, HonoluluShijie Huang PhD Candidate Department of Ocean and Resources Engineering University of Hawai’i at Mānoa **This defense will be held both in person (Holmes Hall 287) and over Zoom** Meeting ID: 862 6019 2680 Passcode: ShijiePHD Climate change has dramatically exacerbated coastal erosion, primarily through the effects of sea level rise, the intensification of tropical storms, and the increased frequency of high-wave events. These processes pose a severe threat to the tourism-based economy and the densely populated coastlines of Hawai‘i, where coastal erosion has become an urgent issue. Compounding the problem, traditional coastal defense structures—such as seawalls, breakwaters, and revetments—have
Three-phase flow simulation of beach erosion induced by breaking tsunami-like waves
Watanabe 112 2505 Correa Rd, HonoluluShijie 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.
