Abstract: An adaptive procedure for parameter identification and noise statistics estimation for multisite streamflow forecasting is presented in this work. The model is a multivariate ARMAX model, formulated in a state-space form, with the Kalman filter used to obtain the optimal forecasts and updates of the states. Model parameters, as well as noise statistics, are updated on-line in an adaptive manner along with the states.
