In this chapter, the Method of Characteristics (MOC) is detailed and used to solve the mathematical models defined in the second chapter, where the reservoirpipe-valve-system is considered. The wave-speed adjustment (WSA) scheme is preferred for the MOC. The numerical method is applied to the elastic pipelines on onehand and to the viscoelastic pipelines on the other hand.

Keywords: Boundary conditions; Initial conditions; Linear interpolation; Method of characteristics; Wave-speed adjustment.
