Hmmm, haven't thought about that. Probably quite some way. I still need
something
there, otherwise it looks like the river just disappears.

Thanks. The water code is adapted from code I found elsewhere, can't
remember where.
If anyone recognises this code, please let me know so I can credit properly

#declare T_Water =
 texture {
  pigment { rgbf <0.975,0.975,1,0.8> }
  finish { reflection { 0 0.85 } diffuse 0.025 specular 0.3
conserve_energy }
 }

#declare F_Water= function { pigment { granite turbulence 0.2 scale
<1,1,4>*5 } }

isosurface {
 function
{y-f_noise3d(x,y,z)*0.075-f_noise3d(x*3,y*3,z*3)*0.05+F_Water(1.5*x,1.5*y,1.
5*z).gray*0.1+0.65 }
 contained_by { box { <-2.1,-15,-30> <2.1,1,20> } }
 accuracy 0.001
 max_gradient 4.5
 texture { T_Water }
 interior { ior 1.33 media { absorption <0.35,0.35,0.25> } }
 hollow
}
