Abstract: The development of vegetation in river may increase flood risks. It plays an important role in influencing the hydrodynamic behavior, ecological equilibrium and environmental characteristics of water bodies. Therefore, it’s important to have suitable prediction of increased resistance caused by vegetation. In the recent years, experimental and numerical models have both been developed to model the effects of submerged vegetation on open-channel flow. This paper describes a new analytic model based on physical equations used to predict hydraulic conditions in vegetated rivers. This model was programmed in two-dimensional software to predict flow characteristic in vegetated flow. Simulations were applied on river reach of Medjerda in Tunisia. The comparison between simulated and observed results shows a good performance of this model in the prediction of flood in vegetated rivers.
