Tsunami, like many other natural disasters leaves people a short time for escape. When talking about Tsunami, the escape time is the period it takes for the wave to start moving from the epicenter, change into a giant wave gradually and reach to a cost. In order to minimize damages of this phenomenon, the escaped time has to be estimated without delay. For this purpose the first needed action is modeling the Tsunami waves. Analytical and numerical models and software that are designed based on them do exist. To have an efficient and rapid Tsunami alarming system all of these options are examined in this project. Then having a reliable model quite a few probable scenarios are propounded. The... 

Potential landslides located in the borders of each water body may generate massive and destructive impulsive waves called landslide-generated waves (LGWs) which can be a major threat to human life and his possessions, offshore and coastal installations, dam bodies and hydraulic structures. This research is devoted to numerical modeling of LGW hazards with focus on the impulse wave generation stage including landslide movement, landslide/water surface interactions and consequent tsunami generation. The main purpose of this work is to study the effects of landslide deformability on the impulsive wave characteristics numerically in an introduced state-of-the-art numerical structure. The... 

A tsunami is a series of tides most commonly caused by the deformation of the sea floor during a submarine earthquake. They are extremely long waves with the distance between successive peaks or troughs on the order of 10’s to 100’s of miles. They are also generated by landslides, volcanic eruptions or more rarely by asteroid impact. These causes change in location on the surface of the water which in turn creates numerous waves that spread out from the zone of turbulence. Few current design codes for coastal structures include tsunami. Even those that do, the bases for taking the hydrodynamic loads into the design are often grossly simplified and may be overly conservation and/or...
