Abstract: 

Depth of water at the upstream of pier will increase when a bridge is constructed. The difference between water depth before and after the bridge construction is usually termed as afflux.   
The purpose of this paper is to apply and evaluate the abilities of Artificial Neural Networks (ANN) to predict this phenomena. Mapping between input data (discharge, normal depth, length to width ratio of bridge pier, contraction ratio and angle of pier axis) and output data (afflux) has been provided by a Radial Basis Function (RBF) ANN based on imperical data produced by experimental measurements. The results show that a RBF artificial neural network including two hidden layers can predict intelligently the afflux and its performance is much better than other conventional approaches.
