The most common hydraulic structures used for discharge measurements in open channels are linear weirs due to their accuracy, simplicity, design, and ease of construction. Linear weirs are also used to increase flow depth, control floods, and regulate flow. Before the actual on-site manufacturing of weirs, their hydraulic properties must be determined with experimental and numerical studies. In this study, experiments were carried out on a rectangular linear weir with dimensions 60 x 30, 30 cm height, 1 cm thickness and a flat crest shape. 2D numerical models of the flow passing over the weir were created using the Fluent program. The data obtained from the experimental and numerical model were evaluated in terms of flow depth, total head, discharge coefficient (Cd) and water surface profile. According to the results, although there are differences between the models in the discharge-total comparison due to the working principle of the 2-dimensional numerical model, the models gave 90%-95% consistent results in the discharge coefficient and dimensionless total head comparison. In addition, the experimental and numerical models were compared visually, and it was seen that the numerical models of the experiments were created with a high degree of accuracy.
