9.1 INTRODUCTION
This chapter presents the application of computational performance of a numerical method by a dynamic model. The model has been presented by method of the Eulerian based expressed in a method of characteristics (MOC). It has been defined by finite difference form for heterogeneous model with varying state in the system. Present work offered MOC as a computational approach from theory to practice in numerical analysis modeling. Therefore, it is computationally efficient for transient flow irreversibility prediction in a practical case. In this work reclamation numerical analysis modeling showed the lining method as the best construction way for reclamation of damaged water transmission line.
