Statistical Analysis Approaches in Scour Depth of Bridge Piers

A local scour is the removal of bed material from around pier bridge. This considered a big problem and great concern for hydraulic engineers. They should find economic solutions this problem. The exaggerated bridge piers leads to many problems whole structure, such as stability that may lead bridge's destruction. paper aims verify depth different shapes uniform flow conditions than those done by previous researchers using prediction models. Where consistency experimental investigations verified multiple nonlinear regression analysis (MNLR), Gene Expression Programming (GEP) Artificial Neural Network (ANN) In comparison values were measured predicted four models (CFD, MNLR, ANN, Gene), it seen ANN model has ability predict Ys/b higher other used in relation values. makes superior predicting value over models, followed model. comparison, R2and RMSE study, had 0.9978 0.0147, respectively, while 0.9800 0.0375, respectively.
