MS Plan A Defense: Evaluation of Coastal Imaging Georectification For Measuring Runup With UAV’s On Hawai’i Beaches
Holmes 287 2540 Dole Street, Honolulu, HI, United StatesGabriel Nelson Masters Student Department of Ocean & Resources Engineering University of Hawai’i at Manoa **This defense will be held in-person (HOLM 287) and Zoom** Meeting ID: 884 1267 3489 Passcode: GabrielMS https://hawaii.zoom.us/j/88412673489 Coastal inundation presents a significant and escalating threat to island communities such as Hawaii, driven by rising sea levels and increasing wave activity. Under these circumstances, precise measurement of wave runup is crucial for accurate coastal hazard assessments, effective mitigation strategies, and sound engineering practices. UAV-based photogrammetry paired with the Coastal Imaging Research Network (CIRN) Toolbox offers a powerful tool for coastal image processing. However, CIRN’s standard
MS Plan A Defense: Path Optimization for Acoustical Oceanography Applications
POST 723 1680 East-West Road, Honolulu, HI, United StatesPrajna Jandial Masters Student Department of Ocean & Resources Engineering University of Hawai’i at Manoa **This defense will be held in person (POST 723) and Zoom** Meeting ID: 832 8033 9161 Passcode: 2025 https://hawaii.zoom.us/j/83280339161 This MS work aims to contribute to underwater acoustic sampling techniques through machine learning. It has two objectives: (1) Optimizing the sampling process for underwater sound fields and (2) Optimizing data assimilation for ocean acoustic tomography. To address the first objective, we developed an approach that leverages autonomous underwater vehicles (AUVs) to sample unknown sound fields. Unlike fixed sensor networks with spatial constraints, AUVs can make
MS Plan A: Numerical Modeling of Wave Dynamics at Ulupa’u Crater: Validation of SWAN and XBeach with Field Observations
Camryn Dillon Masters Student Department of Ocean & Resources Engineering University of Hawai’i at Manoa **This defense will be held in person (POST 708) and Zoom** Meeting ID: 858 0966 0255 Passcode: CamrynMS Zoom link: https://hawaii.zoom.us/j/85809660255 This study aims to validate the SWAN and nonhydrostatic XBeach models by comparing simulated wave transformations to field observations collected offshore of Ulupaʻu Crater, O'ahu. The models were calibrated using site-specific bathymetry and wave conditions to replicate observed wave behavior. The accuracy of each model was assessed using spectral analysis and time-series comparisons with ADCP and pressure sensor data. This work explores the effectiveness
MS Plan A Defense: Resident AUV design and validation for autonomous docking and charging at Kilo Nalu Observatory
Holmes 287 2540 Dole Street, Honolulu, HI, United StatesNorman Chung Masters Student Department of Ocean & Resources Engineering University of Hawai’i at Manoa **This defense will be held in person (Holmes 287) and Zoom** Meeting ID: 839 1898 9765 Passcode: NormanMS Zoom link: https://hawaii.zoom.us/j/83918989765 Near-shore environments are important to oceanographers because of their relationship to the biogeochemical and anthropogenic processes which occur on land and at sea. Some traditional approaches to researching these environments include using undersea infrastructure, such as cabled observatories, and autonomous underwater vehicles (AUVs). Each of these approaches have their own advantages and disadvantages. Undersea infrastructure uses the proximity between near-shore environments and land to
