   Casually, I'm just tweaking this texture. Now I simlified it a bit, 
removing the intersection. The same terrain itself translated a bit is 
enough. There is the relevant part:

  #declare terrain_coast=object{terrain translate Foam_Level*y}
  #declare m_water=
  material{
   texture{
    pigment_pattern{object{terrain_coast rgb 0, rgb 1}}
    texture_map{
      [0 t_water]
      [1 t_foam]
    }
    scale 100 warp{turbulence .3 lambda 3} scale 1/100
    scale 1000 warp{turbulence .3 lambda 3} scale 1/1000
   }
   ...


   The translation amount depends on your scene scale and how much foam 
you want, and the same can be applied to the warps scale.

   The technique is simple, but I also expent many hours thinking on 
that "foam challenge" along the years. Now I figured it casually while 
looking at a foam tutorial by Patrick Merminod for a totally different 
package: Vue d'Espirit.
