| Abstract | ||
| Sedimentation of canals is a big problem where the feeding rivers contain a large amount of sediments. Hec-Ras 5.0, 2016 program is an applied software package for simulation of river network in steady and unsteady flow regime. The aim of this paper is to verify the model simulation with field survey for Al-Hilla river, depending on the bed material and other characteristics. For transport function, Meyer Peter Muller method was used, and Ruby method is used for calculating the fall velocity, with the active layer as a sorting method. In this paper different types of outputs resulted in both tabular and graphical of Al-Hilla river were showed using different effective elements like discharge, velocity, elevation (bed level changes). The results showed that the change in river's bed differed according to the river sections and sediment material type and the concentration of sediment increased in the part of river when pass the center of Al-Hilla city, this concentration reach to 125 mg/L. | ||
