The problem of tsunami wave shoaling and runup in U-shaped bays (such as fjords) and underwater canyons is studied in the framework of 1D shallow water theory with the use of an assumption of the uniform current on the cross-section. The wave shoaling in bays, when the depth varies smoothly along the channel axis, is studied with the use of asymptotic approach. In this case a weak reflection provides significant shoaling effects. The existence of traveling (progressive) waves, propagating in bays, when the water depth changes significantly along the channel axis, is studied within rigorous solutions of the shallow water theory. It is shown that traveling waves do exist for certain bay bathymetry configurations and may propagate over large distances without reflection. The tsunami runup in such bays is significantly larger than for a plane beach.  相似文献

Penetration of internal waves into the ocean’s thickness     

T. G. Talipova  E. N. Pelinovsky  N. S. Petrukhin 《Oceanology》2009,49(5):622-629

The data of beam propagation of internal waves into the ocean are confirmed by several analytical solutions of the linear long wave theory. The obtained solutions are applied to calculate the mode of the internal waves.  相似文献

On 1 January, 1996 at 16:05 p.m. local time, an earthquake of magnitude M = 7.8 struck the central part of Sulawesi Island (Indonesia). It was accompanied by tsunami waves 2–4 m high. Nine people were killed and 63 were injured. A tsunami survey was conducted by Indonesian and Russian specialists. The measured tsunami runup heights and eyewitness accounts are reported and discussed. Historical data on the Sulawesi Island tsunamis are analysed and tsunami risk prediction in the central part of Sulawesi Island carried out for the first time.  相似文献   

Transformation of internal tidal waves over the Guinean shelf     

Yu. N. Goryachkin  V. A. Ivanov  E. N. Pelinovsky 《Physical Oceanography》1992,3(4):309-315

Transformation of internal tidal waves over the Guinean shelf is studied on the basis of theoretical and field research. This area is characterized by the presence of a narrow high-frequency waveguide. Internal tides propagating over the shelf are similar to shock waves. Short-period oscillations with an amplitude of 15 m develop at the wave's fore front. A shock wave is generated at the phase of a syzygial tide.Translated by V. Puchkin.  相似文献   

Generation of long waves by random sources     

E. N. Pelinovsky  E. N. Troshina 《Physical Oceanography》1992,3(2):81-86

A statistical approach is applied to solving the problem of long wave generation due to the ocean bottom shift. Various models of random sources are studied. The dependence of the amplitudinal characteristics of long waves on the time scale of random processes is considered. Results of the solution of the dynamic and random source problems are compared.Translated by V. Puchkin.  相似文献   

The effect of the Airy phase during the propagation of edge waves     

E. V. Golovachev  I. E. Kochergin  E. N. Pelinovsky 《Physical Oceanography》1992,3(1):1-7

Peculiarities of the edge wave evolution a great distance away from the source are considered. It is shown that waveguide dispersion may result in discrimination of the region in a wave train corresponding to the Airy phase. The effect of the discrimination of the Airy wave in the remote zone for the model of a step-like shelf is compared with real edge waves (using the marigrams of tsunami observed in the Sea of Japan in 1983).Translated by Mikhail M.

Amplitude variations of edge waves on a shelf slowly varying in the alongshore direction     

A. A. Kurkin  E. N. Pelinovsky  O. E. Poloukhina 《Izvestiya Atmospheric and Oceanic Physics》2006,42(3):353-361

Within the framework of the linear shallow-water theory, the dynamics of edge waves over a shelf characterized by a cylindrical bottom relief is investigated under the assumption that shelf parameters vary slowly in the alongshore direction. An asymptotic theory and an energy approach are used to calculate the amplitude of the edge wave. In the analytic form, the results are obtained for shelves of three different profiles with parameters varying along the shore: an infinite linear profile, a concave exponential profile, and a stepwise profile.  相似文献   

Propagation of long waves in straits     

E. N. Pelinovsky  E. N. Troshina 《Physical Oceanography》1994,5(1):43-48

The non-linear effects induced when a long wave propagates in a strait of arbitrary cross-section are investigated. Comparative analysis of the wave parameters for straits with different geometries is carried out. The relationships between the wave amplitudinal characteristics, the non-linearity scales, and the parameters of the strait's cross-section are considered.Translated by Mikhail M. Trufanov.  相似文献
