What are some tips for improving accuracy in shallow water flow simulations?

[MartinV]

I'm trying to create a simulation of shallow water flow and I keep getting huge values of variables. Does anyone here have experience with this type of computer simulations?

What kind of stimulation?
What are you trying to find out?
what progam(s) are you using?

The problem with any surface simulation is modeling the interface. You have two different fluids doing their own thing.

what software or 3d engine would you do this in if you wanted to use c++?
