ABSTRACT. Comparison of Different Methods of Modeling the Phenomena of Sediment Transport in Riverbeds. The study of the phenomena associated with sediment transport is important to determine if erosion or deposition will occur in a riverbed, the extent of this processes, as well as the time and distance over which it will occur. For a better understanding of these phenomena, it is necessary to identify and study all the factors and parameters that determine the mechanisms of solid transport processes in the riverbeds. Over time, several researchers have developed different formulas for calculating solid loads, models that were later integrated into various hydroinformatics tools. The use of these tools allows comparing the results obtained by applying various calculation models. This paper compares the results of sediment transport modeling in riverbeds using some of these calculation formulas: Engelund-Fredsøe; Van Rijn; Meyer-Peter & Müller; Sato, Kikkawa & Ashida, respectively Ashida, Takahashi and Mizuyama. The modeling is done on a river sector, using the advanced hydroinformatic tool MIKE11 by DHI. Comparing the results obtained by modeling, using various models, with the data obtained from the measurements make it possible to choose the best model for the studied water course.
