The aim of this research is to model the time series formed by the monthly flows of Caroni River in Venezuela, from 1950 to 2003 using regression based on Support Vector Machines (SVR). The mentioned time series was preprocessed by extracting the trend and seasonal components trough Independent Component Analysis (ICA) and the resulting stochastic series was modeled as a Nonlinear Autoregressive Moving Averaging process (NARMA), of order defined by Singular Value Decomposition (SVD), using SVR. The model was validated by obtaining a prediction error in the flow, lower than traditional statistical models. The results of this study demonstrate the strength of nonlinear computational models to predict river flows.
