Preliminary Study on the Water Level Forecast in the River with Tidal Effect

Forecasting the water level with tidal effect is difficulty,because it is influenced by flood and tidal.This paper treats the water level as time series and compares thewater level forecasted by some model with observed,the result shows that the neural network model is suitable for tidal river and the ARMA(2,1) is suitable for high level forecasting,but for floodriver,the forecasting ability of all models should be improved.
