Hi,
Fluids are a pretty advanced and deep topic...I'm going with the assumption that you are new...I would learn the basics of modeling first (with the aim of learning to model the mountain) before trying to tackle fluids and dynamics.
I don't think this website offers tuts on fluids, but a google search should help you find some that do.
