Oil spreading simulation on GRASS

Hi there,
  I'm doing oil spreading simulation (using GRASS, of course) in coastal area and would appreciate any references for oil spreading and oil polution on the sea. BTW, I'm wondering if anyone out there in the GRASS world is working on related applications. Any help will be very much appreciated.
