Abstract

This study proposes a new approach for determining the optimum parameters of a protective spur dike to control scour around existing spur dikes. Several parameters of a protective spur dike were studied to determine their optimum values, including the angle of the protective spur dike relative to the flume wall, its length, and its distance from the main spur dikes, flow intensity, and the diameters of the sediment. To build an effective prediction model, the polynomial and radial basis function are applied as the kernel function of support vector regression (SVR) for prediction of protective spur dike parameters for scour controlling around spur dikes and their performance were compared to Adaptive Neuro Fuzzy System (ANFIS), and Adaptive Neural Network (ANN). Instead of minimizing the observed training error, Polynomial-based SVR (SVR_poly) and radial basis function SVR (SVR_rbf) attempt to minimize the generalization error bound so as to achieve generalized performance. The performance of proposed optimizer was confirmed by experimental results. The results showed that an improvement in predictive accuracy and capability of generalization based SVR can serve as a promising alternative for existing prediction models.
