Triangular Side Weir Discharge Coefficient Calculation and Comparison Using ANN

Abstract

In this paper, the coefficient of discharge was calculated using Artificial Neural Network (ANN) for two triangular side weir models installed with flow direction and opposite to it. These values compared with that which calculated empirically using Rehbock formula, the variables affecting on this equation where found and analysis using Buckingham (pi-theory) to reduce to minimum variables affecting in side weir flow, the results shown that agreement between empirical method and that calculated using (ANN) with (MSE = 0.00113) and (R = 0.982).
