Previsão Hidroclimática de Vazão de Curto Prazo na Bacia do Rio São Francisco
Benedito Cláudio da Silva,Carlos Eduardo Morelli Tucci,Robin T. Clarke,Walter Collischonn,Martin Corbo +4 more
TL;DR: In this article, the authors presented the result of integration between ETA atmospheric regional model and MGB-IPH distributed hydrologic model, to short-range streamflow forecast, in which a stochastic model was used to correct the forecasted streamflow by the forecasting of hydroclimatic model residues.
Journal ArticleDOI
Precipitation as a proxy for climate variables: application for hydrological modelling
Ayan Santos Fleischmann,Fernando Mainardi Fan,Bruno Collischonn,Walter Collischonn,Paulo Rógenes Monteiro Pontes,Anderson Luis Ruhoff +5 more
TL;DR: In this article, a linear regression curve is used to estimate monthly climate variables from observed precipitation using the MGB hydrological model, which is applied by applying the MGA model to the observed precipitation.
Journal ArticleDOI
Previsões de Curto Prazo de Vazão Afluente ao Reservatório de Furnas Utilizando Redes Neurais Artificiais
Juan Martín Bravo,Olavo Correa Pedrollo,Walter Collischonn,Adriano Rolim da Paz,Cintia Bertacchi Uvo +4 more
TL;DR: In this paper, the authors evaluated the performance of a streamflow forecast model based on a feed-forward multilayer artificial neural network (ANN) model with available rainfall forecasts as additional inputs to the model.
Journal ArticleDOI
