Circular crested weirs are used for flow measurement and water level control in irrigation systems and reservoirs. Using Dressler theory and applying a velocity correction factor at the weir crest section, analytical equations are obtained for discharge coefficient, and velocity and pressure profiles at the weir crest section of circular crested weirs. Existing experimental data are used for validation of the obtained equations. The results of the study indicated that obtained equations have good agreement with experimental data.
► Hydraulic characteristics of circular crested weirs derived using a new theoretical method. ► Dressler theory and variable energy correction factor on the velocity function used. ► Existing experimental data used for validation of obtained equations. ► The obtained equations have good agreement with experimental data.
