Abstract: We consider numerical approximations of a strickly-hyperbolic system with source terms occuring in hydraulics. The interaction of the bottom slope and the friction slope in the Shallow Water equations is a very dominant term which characterises the well-balanced states. We thought it would be interesting to deal with these so-called balance laws with a new numerical processing. At the end, we have been able to run numerical tests. THey simulate smooth transitions as well hydraulics jumps and dry zones.
