Monthly streamflow forecast for National Interconnected System (NIS) using Periodic Auto-regressive Endogenous Models (PAR) and Exogenous (PARX) with climate information

Abstract: This study aims to find a seasonal streamflow forecast model simultaneous to all stations of SIN using periodic autoregressive models with exogenous variables (PARX) using climate indexes. Comparing the results from PAR and PARX Models, this research analyzes the impact on forecasts by using climate information. The proposed models for streamflow forecast has been carried out using natural streamflow data from Operador Nacional do Sistema (ONS) and statistical techniques (such as multiple linear regression and… Show more

“…Recently Ursu E. et.al have used PAR model identification using genetic algorithms and also have done work on application of periodic autoregression process to the modelling of the Garonne river flows [36], [37]. We also find the various application of PAR model on river flow [33] and stream flow [29], [40]. Sarnaglia A. J. Q. et.…”

“…The results of such studies are usually presented in terms of point forecasts (hereafter forecasts) rather than in a probabilistic way, as in Tyralis and Koutsoyiannis (2014). An extensive study on the use of climate index data for forecasting monthly streamflow at 88 locations in Brazil is available in Silveira et al (2017). Another relevant and large-scale study by De Gregorio et al (2018) uses data originating from 300 alpine basins.…”

“…No Brasil, segundo Alexandre (2012), os modelos estatísticos de previsão de afluências têm sido uma ferramenta importante no suporte à tomada de decisões, no planejamento e na gestão de recursos hídricos aplicados ao Sistema Interligado Nacional (SIN). Silveira et al (2017) citam que modelos estatísticos foram propostos em diversos estudos, comprovando que o uso de índices climatológicos como variáveis explicativas em modelos matemáticos proporciona capacidade de explicar regimes de vazões interanuais, destacando os trabalhos de Uvo e Graham (1998), Souza Filho e Lall (2003, Silva e Molion (2004), Rohn et al (2003) e Rocha et al (2007). Silveira et al (2017) citam que estudos como os de Souza Filho e Lall (2003) e Foley et al (2002) são realizados desde a década de 1990 e apontam que o uso de variáveis climáticas pode reduzir incertezas devido à alta correlação dessas variáveis com variáveis hidrológicas.…”
