Non-linear weirs have more passing length than linear ones for a certain value of flow width, so they have more utilization for water surface adjustment, flow control in channels, rivers, and dam reservoir purposes. Labyrinth weir is a common type of non-linear weir that has been considered by researchers in recent decades. The effect of some geometric and hydraulic characteristics appears as discharge coefficient in the head-discharge relationship. For the same conditions, the higher the discharge coefficient, the more flow will pass over the weir. The experimental study is one of the methods to determine the effect of parameters on the discharge coefficient value. Due to the occurrence of complex phenomena that can not be measured or the existence of physical limitations in the laboratory, the use of intelligent artificial methods has become a growing trend in recent decades. The GEP and the SVM are two algorithms with train and test base phases that are used to extract the hidden and complex relationships among dependent and independent variables. In this research work, in addition to the experimental assessment of different geometric and hydraulic parameters on discharge coefficient, the outputs of the two mentioned algorithms have been considered and compared with laboratory results.
