             abstract = "The prediction of the Negro River height at Manaus, Brasil, has 
                         very important economical interests, mainly for the people living 
                         in that region. This work is an attempt to find a model which 
                         explains the heights of the Negro river. The Negro river height 
                         data is checked for nonstationarities over the record length. The 
                         produce used to find the model involves an adjustment of the 
                         series by the seasonal means and standart deviations. Some models 
                         were proposed and comparisons for predicting river heights for 
                         one, two and three steps ahead were done. The chosen model was an 
                         autoregressive model in which the coefficients vary with each 
                         month. The seasonal autoregressive model is compared with other 
                         suggested models in the literature.",
