Side weirs are flow-regulating devices commonly encountered in hydraulic engineering. A side weir is an over flow weir framed at the side of a channel, over which lateral outflow takes place when the water surface in the channel rises above the weir crest. They are widely used for flow diversions in irrigation, land drainage, urban sewage systems and also in intake structures. It is essential for hydraulic engineers to correctly predict the weir discharge coefficient, regarding the technical and economical design of side weirs. Although the discharge coefficient for flow over a side weir has been investigated experimentally by many investigators, an overall acceptable formula or a complete analytical solution of the equation governing the flow does not exist. Although sharp crested rectangular side weirs have been extensively studied, there is a lack of information on the other shapes of side weirs, such as labyrinth weirs. In this study the hydraulic characteristics of flow over labyrinth sharp crested side weirs are adapted to formulate the discharge coefficient, based on experimental data and the artificial neural network method. The discharge coefficient (C
