To study plant cover composition, using six factor method,The comparison was done. The results of studying on sedimentation showed a significant reduction due to vast treatments on the most important kind of erosion, channel erosion. The result showed that pland cover density had no significant changes but plant composition had changed from first class to second class ones. There fore, regarding the goals of the operations done in the project, we can consider it positive and successful.
