Abstract

In this study, DISCHARGE COEFFICIENT in a RECTANGULAR SHARP-CRESTED SIDE WEIR in movable and fixed bed channels was investigated experimentally. The first part of the experiments was carried out in a mobile bed channel with sediment median size of. In the second part, the channel bottom was fixed and experiments were performed. The multiple nonlinear and linear regression models are used to develop empirical equations based on the dimensionless parameters for calculating DISCHARGE COEFFICIENT of the rectangular side weirs. The BED MORPHOLOGY changes in mobile bed channel axis alongside the weir influenced on the flow over the weir and DISCHARGE COEFFICIENT. The accuracy of the proposed models was evaluated using Root Mean Square Errors (RMSE) and Mean Absolute Errors (MAE). The diverted discharges from the main channel were calculated using proposed models and compared with the observed data. In the conclusion, the results obtained from the models are in good agreement with the observed values and the developed models are capable of predicting DISCHARGE COEFFICIENT of rectangular sharp-crested weirs in a reasonable way in movable and fixed bed straight channels. The mean relative errors values for DISCHARGE COEFFICIENT calculated by proposed models are obtained 4.63%, 4.72%, 1.16% and 1.33% for both movable and fixed bed channels.
