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 cm width, 30 cm height, 1 cm thickness and a flat crest shape. 2-Dimensional numerical models of the flow passing over the linear weir were created by ANSYS-Fluent. The data obtained from the experimental and numerical model were evaluated in terms of, total head (HT) and discharge coefficient (Cd) and water surface profile. According to the results, although there are differences between the models in the discharge (Q) – total head (HT) comparison due to the working principle of the 2-dimensional numerical model, the models gave 92.5 % consistent results in the discharge coefficient (Cd) and dimensionless total head (HT/P) 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.Basılı+Elektronikeninfo:eu-repo/semantics/openAccessMühendislik Temel Alanı>İnşaat Mühendisliği>Hidromekanik>Su Kaynakları>Su YapılarıExperimental ModellingLinear WeirsNumerical ModellingSharp-Crested WeirsArticle
