摘要：Open channel flows often come in investigation and intervention scope of the environment engineering. Very often, the water layer depth is weak compared to the horizontal extension of the observed phenomena. This is the case for flows in rivers or channels and of the ground run off. The transition from turbulent Navier-Stokes equations tackled by using the Leibnitz formula. A series of approximation allowing to neglect one or several terms of the Saint-Venant equations is presented. In this study we used Characteristics method as a simplified from Kinematic wave equation for flood routing in the length 61 KM of Karun River. Moreover the process is carried out by MIKE 11 model for estimating the accuracy and agreement of the method together. The results showed that the Characteristics method is applied for this reach of river.
