Discharge coefficient of rectangular sharp-crested side weirs Part II: Domínguez's method

Gene expression programming to predict the discharge coefficient in rectangular side weirs

“…The data sets presented by Emiroglu et al [22] and Bagheri et al [24] were used in this study. Emiroglu et al [22] conducted their experiments in the hydraulics laboratory at Firat University, Elazig, Turkey.…”

“…The water was controlled by a pipe and a sluice gate. In Emiroglu et al's [24] research, a discharge amount between 0.01 and 0.150 m 3 /s was measured with an electromagnetic flow meter (±0.01 L/s sensitivity). Additionally, the discharge results from the electromagnetic flow meter were calibrated using a V-notched weir located at the beginning of the system.…”

“…Bagheri et al [24] conducted experiments on rectangular sharpcrested weirs with different heights and widths within a horizontal rectangular channel 8 m long, 0.4 m wide, and 0.6 m deep. All experiments were carried out under subcritical flow condition.…”

“…They obtained the side weir discharge coefficient as a function of the ratio of the head above the weir to the side weir's sill height and Froude number. Bagheri et al [24] conducted an empirical study on the features of flow passing over a rectangular sharp-crested side weir on the side of a rectangular channel. They analyzed the laboratory results using the artificial neural network and found that the side weir's upstream Froude number is the most effective parameter affecting the discharge coefficient of a rectangular sharp-crested side weir.…”

“…Comparison of result from ANN procedures with these of experimental results clearly indicates that the ANN technique is efficient for the determination of discharge coefficient. [12,7]. It is essential to predict discharge coefficient and the discharge correctly by the hydraulic engineers, who are involved in the technical and economical design of weirs.…”
