To this end implementation of an accurate model relying on effective parameters involved is a reliable benchmark. In this study three machine learning techniques namely extreme learning machine (ELM) multilayer perceptron neural network (MLPNN) and M5P model tree (M5PMT), and three optimization approaches of Runge Kutta (RUN) genetic algorithm (GA) and particle swarm optimization (PSO) are applied for modeling. The optimization and ensemble hybridization approaches are applied in the modeling procedure. For the case of hybrid optimized models the ELM and MLPNN models are hybridized with RUN GA and PSO algorithms to develop six hybrid models of ELM-RUN ELM-GA ELM-PSO MLPNN-RUN MLPNN-GA and MLPNN-PSO. Ensemble hybrid models are developed through coupling the ELM and MLPNN models with the M5PMT algorithm. The data pre-processing approach is applied to find the best randomness characteristic of the utilized data. Results illustrate that the RUN-based hybrid models outperform the GA- and PSO-based counterparts. Although the MLPNN-RUN and MLPNN-M5PMT hybrid models generate better results than their alternatives MLPNN-M5PMT slightly outperforms MLPNN-RUN model with a coefficient of determination of 0.84 and a root mean square error of 0.88. The current study shows the superiority of the ensemble-based approach to the optimization techniques. Further investigation is needed by considering alternative optimization techniques to enhance sediment transport modeling. © 2023 Elsevier B.V.
