Structural damage caused by large waves such as tsunamis is an important concern in many areas of the world. One approach to mitigate this damage is to alter the phycial environment near the shore; the simplest approach is to place levees or other structures to block oncoming waves.Alternatively, one might try to force the wave to to break away from the shore, in order to dissipate its energy before arriving to the point of interest.In this project, we will consider situations of interest such as wave Propagation in channels and use multiphase flow codes to simulate these scenarios.Our goal is to explore alternatives for the design of hydraulic structures to protect specific points of interest. ​​​​​
