The referenced paper "Simulating Ocean Water" talks about this in section 5. Indeed the FFT approach makes this difficult, where a different approach[1] for waves reflecting off obstacles. That approach uses convolution, however you can perform convolution using FFTs[2], so perhaps there's some nice way to combine the two approaches. edit: I just skimmed the papers, and it seems[1] does indeed mention combining the FFT approach with the convolution approach in the section on Ambient Waves.
