Abstract

Forecasting river flow is important to water resources management and planning. In this study, an artificial neural network (ANN) model was successfully developed to forecast river flow in Apalachicola River. The model used a feedโ€forward, backโ€propagation network structure with an optimized conjugated training algorithm. Using longโ€term observations of rainfall and river flow during 1939โ€“2000, the ANN model was satisfactorily trained and verified. Model predictions of river flow match well with the observations. The correlation coefficients between forecasting and observation for daily, monthly, quarterly and yearly flow forecasting are 0ยท98, 0ยท95, 0ยท91 and 0ยท83, respectively. Results of the forecasted flow rates from the ANN model were compared with those from a traditional autoregressive integrated moving average (ARIMA) forecasting model. Results indicate that the ANN model provides better accuracy in forecasting river flow than does the ARIMA model. Copyright ยฉ 2004 John Wiley & Sons, Ltd.
