After briefly introducing all necessary background theory on hyperbolic systems of con. The main objective of this thesis concerns the study, design and numerical implementation of finite volume schemes based on the socalled godunovtype solvers for hyperbolic systems of nonlinear conservation laws, with special attention given to the euler equations and ideal mhd equations. Godunovtype schemes appear as good candidates for the next generation of commercial modelling software packages, the capability of which to handle discontinuous solution will be a basic requirement.
