These artificial intelligence methods benefit from the simplicity, ability, and proper results of modern and advanced computers (Nguyen, Ahn, & Park, 2018;Salmasi, Yıldırım, Masoodi, & Parsamehr, 2013), knowledge based and data based nature, predictions without need of model form, and greater endurance over the data errors (Azamathulla, 2005;Bateni & Jeng, 2007) than statistical models. For instance, Liriano and Day (2001) reported higher performance of the ANN method in estimating scour dimension near a culvert in comparison to the existing empirical equations.…”
