Available in PDF, EPUB and Kindle. Book excerpt: The response of linearized long waves to the eight major Hawaiian Islands is investigated numerically using a mathematical model of the island system. A spline interpolation scheme is utilized to convert the actual soundings of the island bathymetry to a 5.5 km square grid closely approximating the topography of the islands. A time-marching, central difference, explicit scheme is used to evaluate the wave field by the linear, long wave, Eulerian equations of motion and continuity in Cartesian coordinates for a frictionless, homogeneous fluid. The condition of no normal flow is employed at the island shorelines and a localized interpolation technique is utilized at the outer boundary to simulate a free-flow boundary. Verification of the numerical procedure is accomplished by agreement with analytic solutions of steady-state problems involving wave interaction with geometric islands in both constant and variable depth cases. Island response is determined by using a generalized time sequence input with a stipulated spectrum in the tsunami frequency range. This input is time stepped through the model for a duration sufficient to establish a statistical equilibrium within the system. The shoreline hydrographs, which record the time history of water elevation around the islands, are Fourier analyzed to obtain spectra for each shoreline point. These spectra are divided by the input spectrum to obtain transfer functions which represent the relative response of the system to waves in the tsunami period range. Verification of the response analysis is judged in terms of the agreement with the analytic response of a variable depth geometric island to a set of tsunami period waves. A technique for determining the period cutoff of a particular model system is demonstrated by comparison of responses of the same model using coarse and fine grids. The response analysis methods are applied to the model of the Hawaiian Islands for the case of a tsunami originating in the Alaskan region. Transfer functions are shown in averaged and contoured form for the island system and each individual island. The model study reveals that the numerical technique is appropriate for the response study of the Hawaiian Islands, that there are at least nine characteristic periods in the tsunami range to which the islands respond, and that interinsular reflections generate areas of high energy concentrations.

Book Synopsis Tsunami Warning and Preparedness by : National Research Council
Download or read book Tsunami Warning and Preparedness written by National Research Council and published by National Academies Press. This book was released on 2011-04-01 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many coastal areas of the United States are at risk for tsunamis. After the catastrophic 2004 tsunami in the Indian Ocean, legislation was passed to expand U.S. tsunami warning capabilities. Since then, the nation has made progress in several related areas on both the federal and state levels. At the federal level, NOAA has improved the ability to detect and forecast tsunamis by expanding the sensor network. Other federal and state activities to increase tsunami safety include: improvements to tsunami hazard and evacuation maps for many coastal communities; vulnerability assessments of some coastal populations in several states; and new efforts to increase public awareness of the hazard and how to respond. Tsunami Warning and Preparedness explores the advances made in tsunami detection and preparedness, and identifies the challenges that still remain. The book describes areas of research and development that would improve tsunami education, preparation, and detection, especially with tsunamis that arrive less than an hour after the triggering event. It asserts that seamless coordination between the two Tsunami Warning Centers and clear communications to local officials and the public could create a timely and effective response to coastal communities facing a pending tsuanami. According to Tsunami Warning and Preparedness, minimizing future losses to the nation from tsunamis requires persistent progress across the broad spectrum of efforts including: risk assessment, public education, government coordination, detection and forecasting, and warning-center operations. The book also suggests designing effective interagency exercises, using professional emergency-management standards to prepare communities, and prioritizing funding based on tsunami risk.

This book was released on 1998 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the request of the U.S. Army Engineer Division, Pacific Ocean (POD), a numerical model wave response study of proposed improvements to Maalaea smali boat harbor was conducted by the U.S. Army Engineer Waterways Experiment Station's (USAEWES) Coastal and Hydraulics Laboratory (CHL). The study was conducted as a revision and extension of previous studies (Lillycrop et al. 1993, Thompson and Hadley 1 994b) to assess the wave response of various alternative modification plans for the harbor. This report - is focused on the determination of an optimal design plan which would provide the harbor with adequate protection from the incident wave climate. Information provided in earlier reports is referenced in this report, but generally not repeated.
