sw for 2D free surface shallow water?

Rob Snel

You will probably have seen wildwater kayaking on television. More and more this sport tends to fast flowing, straight forward, man made channels. I would like to model some sections of these channels in 2D. There is an enormous amount of software available, but most seems to be unsuitable for this task. Can someone help me which software to choose? (preferably freeware or public domain for even a national sports organisation is almost budgetless; I'm an unpaid volunteer)

charateristics are: free surface, shallow water, incompressible, discontinuities in bottom profile, steady flow, super- and sub critical flow, plenty shock waves.

thanks, Rob
