Dear Jorg

This is a real hot topic, which interests me as well, I have succeed to implement a crude model like of a flux of material proportional to the velocity
     Init { istep = 1 } {
      sU2 = Velocity  
      dqdx = dx("sU2")
    }
and an update of the soil like
   Init {start = 5 istep = 10 } { Zb = Zb - 0.1*dt*dqdx}. 

an example is on the draft figure 5

What are your plans?


cheers
