  • Seminar: U.S. Army Corps of Engineers, Honolulu District Coastal Engineering Program Overview

    Justin Goo, P.E. Chief, Civil Works Technical Branch U.S. Army Corps of Engineers, Honolulu District The U.S. Army Corps of Engineers, Honolulu District Civil Works Program delivers water resource development solutions including navigation safety, hurricane and storm risk management, ecosystem restoration, hydropower, and recreation.  The Honolulu District area of responsibility includes State of Hawaii and the U.S. Territories of Guam, American Samoa, and the Commonwealth of the Northern Marianas Islands. This guest lecture intends to provide an informational briefing on the Honolulu District's coastal engineering mission which involves planning analysis, engineering and design, engineering support during construction, and operations and

  • Seminar: Sustainable Hard and Soft Measures for Coastal Protection

    Dr. V. Sundar Professor Emeritus Department of Ocean Engineering Indian Institute of Technology Madras, India Any stretch of a coastline warrants protection measure when it experiences an erosion rate beyond a threshold value, and when the seasonal sediment transport/littoral drift changes fail to restore equilibrium. The causes for coastal erosion can either be natural, man-made or a combination of both. The natural causes include extreme storm events, action of waves on the coasts, Sea level rise due to climate change, etc. The man-made causes are often related to developmental activities such as construction of ports, fishing harbours, structures for wave

  • Seminar: Wave runup, forecasting, and enhanced observations with a drone-mounted LiDAR

    Zoom Meeting ID______ 935 4503 7290 Passcode: ore792

    Julia Fiedler, PhD Postdoctoral Scholar Scripps Institution of Oceanography University of California San Diego Storm wave run-up causes beach erosion, wave overtopping, and street flooding. Extreme runup estimates may be improved, relative to predictions from general empirical formulae with default parameter values, by using historical storm waves and eroded profiles in numerical runup simulations. For use in a local flood warning system, the relationship between incident wave energy spectra E(f) and SWASH-modeled shoreline water levels is approximated with the numerically simple integrated power law approximation (IPA), wherein broad and multi-peaked E(f) are accommodated by characterizing wave forcing with frequency-weighted integrals

  • MS Plan B Defense: Modeling of hurricane waves for design of coastal infrastructure

    Zoom Meeting ID______ 853 4276 3602 Passcode: U7H0uX

    Giannicola Tumino Di Costanzo Graduate Student Department of Ocean and Resources Engineering University of Hawaiʻi at Mānoa The subtropical Hawaiian Islands are subject to occasional hurricanes that bring the risk of infrastructure damage and financial loss. Determination of hurricane wave conditions in terms of return period is important for coastal infrastructure design and risk management. This study assembles and validates a hurricane wave model and utilizes the model to determine probabilistic design wave conditions for a study site at west Maui. The Delft3D software, which includes a parametric hurricane model and SWAN (Simulating Waves Nearshore), is used to determine significant

  • MS Plan A Defense: Morphodynamic changes due to calm-moderate wave forcing: A case study of Waikiki Beach

    Zoom Meeting ID______ 999 8388 9554 Passcode: ORE

    Julianne Kalksma Graduate Student Department of Ocean and Resources Engineering University of Hawaiʻi at Mānoa Sea level rise, erosion, and the wave climate influence Waikiki Beach on the South Shore of Oahu which is a popular beach in metropolitan Honolulu. In response to recent erosion events and ongoing beach nourishments, weekly surveys have been collected for the past 3 years, from April 2018 through December 2020, to better understand coastal morphology. Local studies found detailed two-dimensional morphological structures; however, no direct relationships between the offshore driving ocean conditions and Waikiki Beach have been established. Other previous works relate the wave

  • Seminar: Flood and Erosion Hazard Mitigation for North Shore, O’ahu

    https://hawaii.zoom.us/j/93596087383

    Jonathan Chapman, John Melve & Andrew Storey Graduate Students Department of Ocean and Resources Engineering School of Ocean and Earth Science and Technology University of Hawaiʻi at Mānoa Zoom Meeting Link: Meeting ID: 935 9608 7383 Passcode: OREseminar https://hawaii.zoom.us/j/93596087383 The ORE 783 Capstone Design course invited detailed proposals from engineering students for FEL-1 and -2 level studies. The aim is to assess technical, economic, and regulatory feasibility of engineering measures that can reduce flood and erosion hazards on Oʻahu’s North Shore while taking into consideration climate change. We present three preliminary design solutions to mitigate three respective challenges experienced along

  • Seminar: The Resilient and Sustainable Engineering (RiSE) Team at Oceanit and Combatting Hawai’i Shoreline Erosion

  • MS Plan A Defense: Seasonal wave climate anomalies on the North Shore indicative of erosion conditions

    https://hawaii.zoom.us/j/98606638344

    Andrew Storey Master’s Student Department of Ocean and Resources Engineering University of Hawaiʻi at Mānoa Zoom Meeting Link Meeting ID: 986 0663 8344 Passcode: ORE https://hawaii.zoom.us/j/98606638344 Sea level rise and seasonal wave climate have beset the Sunset Beach shoreline community with several episodic erosion events that have impacted local infrastructure. In support of the local community, the US Army Corps of Engineers (USACE) Honolulu District has employed a series of remote sensing technologies at Sunset Beach to generate a regional sediment budget to better inform the community of their situation. The objective of this study is to explain the more
