چکیده
Within the framework of linear theory, applicable far from the shore, we investigate the two-dimensional propagation of waves generated in the ocean by a sudden seabed deformation.

Linear theory of wave generation by a moving bottom Denys
The computation of long wave propagation through the ocean obviously depends on the initial condition. When the waves are generated by a moving bottom, a traditional approach consists in translating the “frozen” sea bed deformation to the free surface and propagating it. The present study shows the differences between the classical approach (passive generation) and the active generation where t...
متن کاملGPU-SPH simulation of Tsunami-like wave interaction with a seawall associated with underwater
Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to...
متن کاملEvaluation of underwater acoustic propagation model (Ray theory) in a river using Fluvial Acoustic Tomography System
Underwater acoustics is widely used in many applications, such as oceanography, marine biology, hydrography, fishery, etc. Different models are introduced to simulate the underwater acoustic propagation in the oceans and the seas. In this study, the Ray Theory model is used to simulate the acoustic wave propagation in a shallow-freshwater river (Gono River) located in western part of Japan. The...
متن کاملThe study of effective stress and pore water pressures in the foundation of a concrete gravity platform affected by loads due to waves, currents and wind in the Persian Gulf
It is proposed to use a single base platform in the Persian Gulf considering its low depth and more appropriate environmental conditions in comparison to North Sea and Mexico Gulf where this kind of platform is very popular. The pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. Using SACS 5.3 sof...
متن کاملNumerical Modeling of water-waves induced by landslides with WC-MPS method
The rapid movement of sediments, which is often induced by a very erosive and transient flow in rivers and rivers, causes a lot of geomorphology and engineering problems. Failure of the dam with a moving bed, submerged landslide, sedimentation flushing in reservoirs are just a few examples of these problems. The study of waves is challenging due to the interference of several complex physical p...
