Book excerpt: The important wave parameters to be considered for tsunami model studies are wave height and period, and wave-front orientation. The first two of these parameters can be determined by marigraphic measurements or by visual observations; however, wave-front orientation has never been accurately observed at the problem site (Crescent City, Calif.). A digital computer program was written to plot wave rays from three recent epicentral locations to Crescent City to obtain approximate tsunami-front orientations. The refraction diagrams were checked by comparing the computed and actual arrival times of the wave fronts. The actual arrival times were obtained from recording tide stations at Crescent City and Hilo, Hawaii. Initial wave-front orientations near the earthquake epicenter were either assumed or taken from the literature, A tentative frequency relation was derived and a risk-duration relation was prepared from the frequency relation. The selected values of the test-wave dimensions (height and period) and orientation determine, to a considerable extent, the model configuration necessary to ensure results sufficiently accurate for purposes of the model study. Since experience in the design and operation of long-period wave models is scant, it was deemed necessary to conduct preliminary tests utilizing a pneumatic wave generator in a two- dimensional flume. The results of these tests were compared with theoretical predictions from an idealized mathematical model and on the basis of these tests, a preliminary model design was proposed.

This book was released on 2009-06-06 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2004 Indian Ocean tsunami was triggered by a 9. 15 magnitude earthquake (MELTZNER et al. , 2006; CHLIEH et al. , 2007) that occurred at 0:58:53 GMT, 7:58:53 LT (USGS) (t ). The epicenter was located at 3. 3 N, 95. 8 E (Fig. 1) with a focal depth of EQ approximately 30 km. The earthquake was responsible for a sudden fault slip estimated on average from 12–15 m (SYNOLAKIS et al. , 2005; LAY et al. , 2005) to 20 m (FU and SUN, 30 2006). The seismic moment estimate (Mo = 1. 3 5 9 10 dyne-cm), based on the Figure 1 Locations of video recordings, recovered clocks, and reliable eyewitness observations. 1: Coastal plains ?ooded by the tsunami; 2: non-?ooded coastal plains; 3: uplands.

The video taken at Uteuen Badeue, on the eastern edge of the Banda Aceh Bay, was recorded by the chief of the Fishery Regional Of?ce from the top of a cliff. The movie that was shot near the Baiturrahman mosque in downtown Banda Aceh has been shown worldwide on TV. The one at Peukan Bada has been recorded during a wedding party. The last two movies were analyzed in detail in order to calculate the tsunami velocity (FRITZ et al. , 2006). Vol.

Download or read book Coastal Protection written by Pile Buck and published by Lulu.com. This book was released on 2012-10 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: With today's problems surrounding shoreline protection, this book should be of great assistance. This manual contains a compilation of 2 Navy and 2 Corps manuals all relative to the subject of coastal protection and the affects tidal action has on our shorelines. The titles included are: Coastal Protection is a U.S. Navy publication which deals specifically with waves and their characteristics. In order to prepare safe designs, the normal and extreme waves which will act against the structure must be evaluated so that a design wave can be selected. Pilebuck takes the user through this phase into the application of data to actual design of breakwaters and seawalls. Storm Surge Analysis: High tides and wind-generated waves combine to provide a potential for abnormally high water levels and flooding during hurricanes or other serious storms. An understanding of this phenomena is essential in order to plan control structures or design others.
