Interaction of the strongly nonlinear internal solitary wave of second mode with bottom step: breather formation

Abstract

Second mode internal waves are widespread in offshore area, and they are frequently follow the first mode internal waves on the oceanic shelf. To study the main properties of interaction of second mode internal waves with bottom features we consider simple configuration of numerical tank with a bottom step. The most interesting is the transmitting regime with the range of block parameter 0.5<B<4. The dependence for transformation coefficients (reflection and transmission) on the parameter of blocking are similar for incident long and intermediate waves of second mode. consider simple configuration of numerical tank with a bottom step.
