Effects of Stratification on Multi-layered Tsunami Waves

Numerical Model for Multi-Layered Tsunami Waves

“…However, interactions within the layers for a two-layer fluid are significantly different than a three (or more) layer fluid. Top surface is having effect from immediate lower layer only, which is same for both the models; however, intermediate layer is having effects from both the lower layer and upper layers and lower layer is having effects from all the upper layers (Imteaz et al, 2009). Imteaz et al (2009) provided detailed derivation of multi-layered tsunami wave and flow equations based on Navier-Stokes equation.…”

“…From the derived equations, it is found that momentum equation for upper layer is not affected by the properties of adjacent layer (layer underneath Properties of all these equations were described in detailed by Imteaz et al (2009). Also, wave celerity of each layer was deduced as follows: …”
