On the basis of drainage network generalization and water-sediment characteristics analysis,a support vector machine model for simulating the flow-sediment transportation of Jingjiang River-Dongting Lake network was established.The simulated results show that the measured values are in good agreement with the fitted values,and fitting accuracy is significantly higher than that of artificial neural networks and linear regression methods.
