I'm not sure of the specifics of water flow, but the A*
algorithm is used in lots of places. You can find an
explanation, psuedo-code, and LISP implementation in:

@Book{ tanimoto87,
  author = 	"Steven L. Tanimoto",
  title = 	"The Elements of Artificial Intelligence: An
		 Introduction using {LISP}",
  publisher = 	"Computer Science Press",
  year = 	"1987",
  editor = 	"Algred V. Aho and Jeffery D. Ullman",
  volume = 	"11",
  series = 	"Principles of Computer Science Series"
