Brief Review on Water Level Forecasting for Tidal River

It is difficult to forecast tidal river level because of the fact that flood of a tidal river results from the combined effect of upstream runoff and downstream tide.The basic methods and study process of the tidal river water level forecasting were analyzed,and the real-time correction methods used for water level forecasting were summarized.In addition,some keys of future study on water level forecasting for a tidal river were given.
