Abstract
The presentation of appropriate patterns and standards for vegetative cover planting for the management and efficient use of aqueducts, streams, and rivers in order to reduce the risk of flooding, undesired soil erosion and optimal utilization of water resources, so as to respond to current and future needs, is of high importance. In this research, the effects of vegetative cover on the flow regime were studied through modeling using FLOW 3D software. 18 models were generated with different plant densities and inflow velocities in the modeling software and the results of the modeling were compared after plotting the velocity profiles, average velocity, and channel height. The results showed that the impact of vegetative cover on performance will be different depending on the type of inflow velocity.
