time varying sea surface scattering

I am very new at COMSOL. I have a simple problem but i guess it can be hard to implement in COMSOL.
I am working in 2D domain. I want to model plane wave (can I create it for a finite duration?) scattering from a time varying geometry. Simply, there is a rectangle shape. But top boundary of rectangle is not flat. It is a curve which is formed according to spectrum of sea surface (Matlab livelink). And this boundary will change in every time step according to velocity of sea surface. Can I achieve this? Can I change the geometry without changing the physics in every time step? By the way other three boundaries of the rectangle is PML. Time varying boundary is sound soft interface (water-air).
