Searching an algorithm.

	If you manage to get a copy of the algorithm could you please send a
copy to me se4ap at dmu.ac.uk. I believe my friend is doing a project that
would be greatly helped by that algorithm. Or any other algorithm 
involving water flow. 
	His project is concerning displaying the effects of water flow over time

	Thanks in advance
