英文摘要	The standard support vector machine (SVM) model was simplified and improved by particle swarm optimization. Taking the gauged yearly runoff and sediment yield data from 1954 to 1997 and monthly data from 1993 to 1997 which were gauged at Ganguyi hydrological station in the Yanhe River Basin in the Loess Plateau, the proposed algorithms, together with the widely used SVM algorithms and back propaganda artificial neuro network, were used to simulate and estimate the yearly runoff and sediment yield from 1993 to 1997 and monthly distribution in 1996. The estimated results by the different algorithms were compared with actual data in terms of relative error, mean relative error, root-mean-square error, consistency index and coefficient of efficiency. The results demonstrated that SVM algorithms can produce better simulations than artificial neuro network model and the proposed algorithms in this paper can produce the best simulation performance among all the algorithms, therefore, they can be potentially used in runoff and sediment yield forecasting in the basin. ?, 2015, Editorial Board of Journal of Basic Science and Engineering.
