The article considers empirical data on the influence of aquatic and near-water vegetation on the level regime of the canal during the period of minimum flow. Based on field studies in the HEC-RAS environment and the Chezy formula, simulation models were selected. Using a simulation model, numerical experiments were carried out to obtain new knowledge in the field of understanding the influence of aquatic vegetation on the parameters of a watercourse. The results obtained allow us to conclude that the existing water associations during the period of minimum flow are capable of creating significant hydraulic resistance along the canal bed and more than doubling the flow levels.
